The Statistical Farmer

June 30, 2012 4 comments

I haven’t been doing very much resource gathering lately, but I used to do a fair bit of it in the past; to alleviate the boredom somewhat, I ended up collecting various statistics about it. They might be useful for other people as well, so I figured I’d post them here.

(A small disclaimer first: most of the statistics in this post are based on gathering done in Poitain in 2010 and early 2011. So I don’t claim that they still apply now and/or for other zones, though on the other hand I haven’t seen any good reason to believe that things such as drop rates might be any different nowadays or that they might be different in other zones.)

I was particularly interested in estimating the probability of getting rare resources. According to an old developer post in the testlive forum, this probability is 3% for T1 resources, 2% for T2 resources and 1% for T3 resources. I’m not completely convinced if that’s really the case; some of the results I got during gathering seem pretty incompatible with this simplified scheme, and I got the impression that each resource has a different probability of getting a rare.

Another very interesting development for gatherers like me came when they introduced the Fortuitous Vittles in the 1.06 patch. This is a consumable item that becomes available from the Brewmistress in your guild city tradepost when your guild renown level is at least 12. It costs 1 gold and gives you a 1 hour buff that increases your chance of getting rare resources. This of course leads to questions like, does it actually work? How much does it increase your chance of getting rares? And is it worth paying 1 gold for?

Well, I think the best way to start answering these questions is to gather lots of resources, count how many rares you got, and thus get a rough idea of what’s the probability of getting a rare resource from this node. So, without further ado, here’s a table with my results:

Resource Without vittles With vittles
Common Rare # common # rare % rare # common # rare % rare
Gold Platinum 5469 83 1.5% 11433 260 2.2%
Copper Tin 6058 189 3.0% 10486 475 4.3%
Electrum Illustrium 4100 87 2.1% 10045 321 3.1%
Iron Aurichalcum 1700 30 1.7% 1418 59 4.0%
Basalt Adamant 5676 63 1.1%
Duskmetal Blue Iron 3504 38 1.1% 914 21 2.2%
Oak Soulwood 1900 13 0.7%

Estimating the probability of rare drops

Now, before we continue, it might be worthwhile to remark that these probabilities can be tricky to estimate, especially because they are low. Suppose that you are interested in a particular resource and that each time you click on its node, the probability of getting a rare is p (as we saw in the table above, p will usually be somewhere in the 1% to 4% range). Now suppose you click nodes of this type n times. Then the probability of getting exactly k rares is binom(n, k) pk (1 − p)nk. (This is called the binomial distribution; see e.g. the Wikipedia or Mathworld for more.)

This is shown in the following chart for n = 100 and for p = 1%, 2% and 3%.

So, let’s say we clicked nodes of this type 100 times and got 2 rares in the process. But we don’t know the real value of p yet, of course — that’s why we started digging in the first place, to estimate p! So what can we say about p now?

Certainly it’s tempting to say that p = 2/100 = 2%. In fact, that’s what the table we saw earlier in this post is based on. And indeed no other value of p will give us a greater probability of k = 2 rares from n = 100 tries than p = 2% will. But as you see from the chart above, it’s also perfectly possible (just a bit less likely) to get 2 rares from 100 tries if p is 1% or 3% (or indeed any other value). So we can’t be very sure about p just yet; maybe the real p is 1% and we got lucky, or the real p is 3% and we were a bit unlucky.

Let’s keep digging until we’ve clicked the nodes n = 1000 times. What’s the probability of getting exactly k rares now?

You can see that the distributions overlap quite a bit less now, but they still do overlap to a certain extent. We’ll never be able to be completely sure about the correct value of p, but we can be a bit more sure now than we were at n = 100. Suppose that we got k = 23 rares from these n = 1000 clicks on nodes. Now we might feel comfortable in saying that p = 1% is most likely out of the question. If p were 1%, there would be a 95% chance that we’d get somewhere from 5 to 17 rares; so we would be very unlikely to get 23 rares if p were just 1%. But what about p = 3%? Of course it’s more likely that we get 23 rares at p = 2% than at p = 3% (and at p = 2.3% getting 23 rares would be more likely than at any other p, but we might speculate that the developers have chosen relatively ‘round’ numbers for values of p); but even at p = 3%, getting 23 rares isn’t that unlikely.

One way to approach this is by thinking in terms of confidence intervals. Given an n and a p, we can look for the narrowest range of k that accounts for some given amount of probability, e.g. 95%. As we saw in the previous paragraph, at n = 1000 and p = 1%, there’s a 95% chance that k will be in the range 5…17. At p = 2%, there’s a 95% chance that k will be in the range 12…29; and at p = 3%, there’s a 95% chance that k will be in the range 20…41. We see that these ranges overlap a little, so if our k falls into an area where the ranges overlap, we might be uncomfortable with committing to any particular p. As we keep digging and n increases, these ranges gradually stop overlapping; so we could decide to keep digging until these ranges stop overlapping.

Of course we could take a percentage lower than 95%, and then these ranges would be narrower in the first place and it wouldn’t take such a large n for them to stop overlapping (but then we’d also be less sure that we have the correct value of p). And on the other hand, we could allow other values of p besides 1%, 2% and 3%; we could consider p = 1.5% and so on; each of these would again have a range of its own, so it would take an even bigger n to prevent the ranges from overlapping.

(A concrete example: in the ‘without vittles’ section of the table at the start of this post, we saw that I got 5439 gold and 83 platinum; so if we take n = 5439 + 83 = 5528 and p = 1%, it turns out that there’s a 95% chance that we’ll get somewhere from 40 to 69 rares. So if the drop rate of platinum was really just 1% (like the developer post linked to at the start says), it would be very unusual to get 83 platinum from 5528 clicks on gold nodes.)

Or we could look at it from the opposite direction. Suppose that we are given an n and a k (a result of our back-breaking digging :P); now we find that for some values of p, this k would fall into the 95% range, whereas for p‘s that are too low or too high, our current k would be either above or below that range. In other words, we might say that at some values of p, our current k is ‘likely’ (in the sense of belonging to the 95% range for that p) whereas for other p‘s it’s ‘unlikely’. The values of p for which this k is likely again form a range, and we might simply report this range instead of (or in addition to) the value of p for which our current k is the most likely (that is of course p = k / n).

In our above example with n = 1000 and k = 23, we would find that this k lies within the 95% range for any p from approx. 1.56% to approx. 3.48%. This gives us a better idea of just how wide a range of possible values of p we must admit, if we want to be really quite sure that we’re discarding only such p as would make our current k really unlikely.

Another example: at n = 10000, k = 200, the range of p‘s that we get by this method is from 1.75% to 2.30%. Thus, after digging 10000 units of a resource, we can be pretty confident that we can estimate the probability of rares to approximately half a percent.

Do Fortuitous Vittles work?

Before we answer this question, let me rant a bit. Surprisingly many people seem to approach this whole business of gathering rare resources with an annoyingly poor grasp of probability and statistics. They buy the vittles and think of it as a guarantee that they’ll be shovered with rare resources during that hour. Then you get complaints along the lines of ‘I gathered for 1 hour without vittles and got 4 rare resources, then I gathered for 1 hour with vittles and got 2 rare resources, so clearly the vittles don’t work’.

What these people don’t understand is that because the probability of getting a rare is fairly small (even with vittles), there is considerable variance in the number of rares you’ll get from one hour to another. Thus it’s perfectly possible to be lucky for one hour while gathering without vittles, and to be unlucky for one hour while gathering with vittles, and to get more rares from the first hour than from the second.

We can illustrate this with the same sort of chart that we’ve seen above. Suppose that the vittles increase the probability of a rare resource from 1% to 2%. What’s the probability of getting k rares if you have clicked the nodes of this type n = 100 times?

I cut off the chart after k = 6 because all the remaining probabilities are so low (amounting to less than 1% all together).

As you can see from this chart, going from p = 1% to p = 2% has certainly increased our chances of getting rares, but outcomes with a small number of rares are still perfectly possible even at a higher p. Suppose you try clicking nodes 100 times at p = 1%, then you take vittles and click nodes another 100 times at p = 2%. What’s the probability that you will get no more rares after taking vittles than you did before taking vittles? It turns out that this probability is depressingly high — around 31%. So you might say that there’s a 31% chance that a statistically illiterate gatherer would complain that vittles don’t work for him.

But 100 clicks isn’t very much. If you’re gathering resources of just one type, you can easily click those nodes 200 times in 1 hour. If we repeat our calculation with n = 200, it turns out that the probability of getting no more rares with vittles than without is just 16%.

At n = 1000, this probability drops to approx. 2.5%. That’s not very much, but on the other hand 1000 units of resources is quite a bit. If you gather for 1 hour here and 1 hour there, and if you gather multiple resources at the same time, it might take you a week or more to gather 1000 units of a particular resource. And 2.5% isn’t that small either — it’s 1 in 40. In other words, if you’d have lots of gatherers gathering one week without vittles and then one week with vittles, 1 in 40 of these people would find that he got no more rare resources in the second week than he did in the first! Of course he’ll go and write a forum post to complain about it. But you presumably won’t hear from the other 39 for whom the vittles evidently worked fine.

In other words, yes, you can have bad luck. You can even have long streaks of bad luck. Every now and then someone will have a long streak of bad luck, and sometimes that someone will be you. This is not a sign that something’s wrong with the drop rates or with Funcom’s pseudorandom number generators. In fact, if such streaks of bad luck didn’t happen — that would be a sign that something’s wrong. (More concretely, it would be a sign that the probability of getting a rare on any particular click is not independent of what has been happening on other clicks. It would suggest that the resource nodes have evolved some self-awareness and memory, perhaps they have even been connected into a hive-mind, and it’s only a matter of time before they will take revenge on the players that are so inconsiderately whacking at them with their pick-axes. In Soviet Hyboria, basalt gathers you!)

Finally, let’s repeat the calculation for n = 10000. That’s a lot of gathering — several months’ worth, in fact, for most people. So if you gather 10000 units without vittles and then 10000 with vittles, what’s the probability that you’ll get no more rares from the second batch than you did from the first? This turns out to be approx. 1.5 · 10−7 %, or 1 in 669 million. So, if you were gathering diligently with vittles not for a week, but for several months, and got no better results than without vittles — then you’re welcome to complain. But no sooner.

* * *

So I guess the main point of all my statistical ranting in this post is that you need a large sample — a large value of n — before you can say anything decent about drop rates and such.

(Coming Soon™: a similarly grumpy statistical argument can be made about the issue of loot drops. I’m sure that your guild, like every other, has a sob story about how some particular piece of raid gear Just. Won’t. Drop. for them. Like, you’ve been raiding since 1960, barefoot and in the snow, it was uphill and against the wind both ways, and that particular piece of gear dropped just once (and the guy that won it has long since stopped playing, of course). And you and your guildies occasionally bitch about how Funcom’s loot tables are bugged and their random generators are unfair. Right? Right. Every guild has such an item. For me it was T2 guardian wrists. But you know what? This is perfectly normal. In fact it would be strange if you didn’t have any such mysteriously rare item.)

But really, do Fortuitous Vittles work?

Anyway, based on the results in the table at the start of this post, we can pretty confidently say that the Fortuitous Vittles do indeed increase the probability of getting a rare item. So in that sense they do work.

That leaves us with the question of whether they are worth the cost. This of course depends on such things as which resources you’re gathering, how efficiently, and what’s their price on the tradepost. (And of course you might not want to base your decisions purely on economic considerations. I know some people who, if they need material X, by golly they will dig material X, even if they could save time by digging the more valuable material Y, selling it, and spending the money to buy X on the tradepost. I never quite understood this point of view but I guess it means a lot to them to be using materials that they have gathered by themselves.)

I don’t think I can do much more than present a sample calculation, but in the end you’ll have to check the prices on your own server to decide which materials are worth gathering and whether you should be taking vittles or not.

Let’s assume that you start in an instance of Poitain with full nodes, that no other gatherers are interfering with you, and that you focus on gold, electrum and copper nodes. In my experience, this means you can click approx. 90 times on each type of node in 1 hour.

Thus, based on the drop rates from the table at the start of this post, we will gather, on average, the following:

  • without vittles: 87.3 copper, 2.7 tin, 88.1 electrum, 1.9 illustrium, 88.7 gold, 1.3 platinum;
  • with vittles: 86.1 copper, 3.9 tin, 87.2 electrum, 2.8 illustrium, 88.0 gold, 2.0 platinum.

How much is this stuff worth? Let’s take the current prices on the Crom server as an example: 100 copper = 16s; 100 electrum = 15s; 100 gold = 70s; 1 tin = 60s; 1 illustrium = 70s; 1 platinum = 82s.

Thus, what you gather without vittles in 1 hour is worth approx. 494s; what you gather with vittles is worth approx. 678s. If we subtract the 5% trader fee (which you’ll have to pay if you sell your resources on the tradepost), and if we furthermore subtract 1g in the case of vittles, we see that your hourly income was 469s without vittles, and 544s with vittles.

So from that point of view, the vittles are still worth using, but just barely; they were a lot more attractive in days when resources were selling at higher prices than now.

(Of course, another thing to consider when deciding whether to use the vittles is that, once you have taken them, you really should try to gather as efficiently as possible for the next 1 hour until the vittles run out, otherwise you’ll have wasted some of your money. Whether this is a good or a bad thing is, I guess, a matter of perspective. You might see it as a helpful encouragement to concentrate on gathering, or as an unwelcome constraint that prevents you from jumping into dungeon groups that might be forming around you in the next hour.)

Jealous prospectors

How likely is it that your gathering will be interrupted by mobs? I haven’t kept as much statistics on this as I did on the rare drop rates, partly because it was more of a hassle and partly because I wasn’t as interested in this. In particular, this means that the sample in the ‘with vittles’ part of the table below is too small to get a decent idea of the underlying probabilities. Nevertheless, here are the results:

Without vittles With vittles
Number of nodes clicked 26736 1329
Times interrupted 2040 9.8 % 94 8.5 %
Of which by minibosses 881 30.2 % 30 24.2 %

Thus, it doesn’t seem that the vittles affect being interrupted by the mobs in any way. When you click a node, the chance that you’ll get interrupted is about 10%; and if you do get interrupted, there’s a 30% chance that it will be by a mini boss.

Killing Keaira

June 28, 2012 Leave a comment

Keaira, a.k.a. the Raven, is a character that has a prominent role in a big quest arc in the mid-level range (40s and early 50s); finally you meet her as an actual NPC standing in the Amphitheatre of Karutonia, right near the entrance. (You might also remember her from the 2007 trailer, which was also included with the game itself until the expansion was launched.) Later you meet her again as part of the Shadows of Jade quest chains in Khitai, and you can even get to fight her as a T4 raid boss in the Memory Cloud encounter.

In the Amphitheatre, she is unattackable by default, but there is a loophole. You might remember the long quest chain in Ymir’s Pass: Niord in the Aesir camp sends you to find Aevar, their shaman; the shaman then asks you to bring hearts and kill the Son of Ymir, then break the seals of Karutonia and go talk to Bellona; she then sends you into the Amphitheatre, where you will then have to talk to Keaira and then go kill the Devourer. This is the quest chain that has two very nice purple cloaks (Cloak of Hugin and Cloak of Munin) as the final quest rewards.

Anyway, if you’re at the point in this chain where you have to talk to Keaira, one of the first things she will ask you is to guess who she is. As with most quests in the game, option 1 is the one you’re supposed to use; but if you instead choose the option 2 and insult her (“you’re a filthy trollop” :P), she will attack you, and your entire group can then fight her and kill her.

She is marked as a raid boss, with skulls next to her name and everything. Given the amount of HP she has (3 million — that’s 50% more than e.g. Vistrix!), this is not unreasonable, but apart from that she’s very much like any plain old open-world boss (except that she hits a little harder); she doesn’t have any special abilities or require any special tactics, she’s vulnerable to CCs and she doesn’t run very fast, so you can easily kite her if needed.

In principle you could even solo kill her; the main problem with that is that it would take you a very long time due to her high amount of HP. I tried it with my guardian and took 5% of her health in 13 minutes; extrapolating from that suggests it would take me more than 4 hours to kill her. Later we brought a group of 4 people and killed her in 16 minutes; with better DPS it could of course go considerably faster as well. (These were all level 80 characters, of course. I’m not sure if a group at a level appropriate for the rest of the Amphitheatre, i.e. around 63, would be able to kill her.)

She didn’t drop any loot, but surprisingly we got 264400 AA XP each.

P.S. See also this interesting forum thread with pictures of Keaira cosplay 😛

Assorted Concoctions

June 23, 2012 1 comment

In the hub cities (Khemi, Conarch Village, Old Tarantia) there are NPCs called Provisioners, who sell crates of level 80 food and potions. They also sell something called Crate of Assorted Concoctions, which costs 19.50 silver; when you open it, you get 3 (or, rarely, 4) items from among the following: blue level 80 potions, stacks of green level 80 food/potions, and social armor.

I bought and opened 1000 crates on the testlive server to estimate how frequently you get which item. For the stacks of green level 80 food and potions, I also computed the average stack size (based on just 100 crates, as it’s a bit more time-consuming). The following table shows the results:

Group Frequency
(in 1000 crates)
Item Average stack size
Green level 80 potions 660 stack of Daggamalt 49.3
411 stack of Moonspill 42.0
387 stack of Sweetpressed Haste 41.2
Blue level 80 potions 29 Absolute Moonspill
29 Dire Sweetpressed Haste
31 Potent Daggamalt
Green level 80 food 652 stack of Leg of Fena 20.1
379 stack of Red Devilled Dates 17.3
422 stack of Cynosural Ale 20.9
Social armor 24 Eyepatch
29 Loincloth
21 Seafaring Vest
15 Stitched Rags
27 Torn Rags

Among the social items from this list, the Eyepatch is probably the most interesting; as far as I know, you can’t get it anywhere else in the game. The other items drop (under different names) from low-level mobs in Tortage Island. (And those mobs also drop several other pirate-themed items that don’t drop from the crates.)

As we can see from the above table, you need to open on average approx. 41.7 crates to get an eyepatch (1000 crates / 24 eyepatches); if we multiply this by the cost of a crate, we see that getting an eyepatch will cost you on average 8.13 gold. I’ve seen one for sale at 6.5 gold on Crom today — a pretty good deal for the buyer.

The HP of solo mobs in Khitai

June 10, 2012 2 comments

Measuring mob HP

Lately I’ve been somewhat obsessed by the idea of measuring the amount of hit points (HP) that various mobs have. In principle this is very easy: you kill the mob and analyze the combat log, summing up the amount of damage done to it and subtracting any healing that the mob may have received. In practice it turns out that these results are annoyingly imprecise; if you repeat this several times with the same mob, you’ll get a slightly different amount of HP each time.

Partly this is because your last attack, the one that kills the mob, may have exceeded the amount of HP the mob had left at the time; e.g. if the mob was down to its last 100 HP and you hit it for 300 HP, 300 is what will get written in the combat log and you’ll end up overestimating its HP by 200. To minimize this problem, I was playing my necro and finishing off each mob with a few whacks of my talismans; such melee attacks are extremely feeble since a necro doesn’t have much strength and combat rating.

Despite this precaution, there is still more variance in the results than I’d like; I’m not sure what other source of error there is. Perhaps the game deliberately selects a mob’s HP at random, from a certain (rather narrow) range, when spawning that mob.

A model for the HP of Khitai solo mobs

I was going around the Khitai level 80+ playfields, killing various kinds of mobs and writing down their HP. Gradually a very interesting pattern emerged.

You find that, on each level, the amounts of HP that mobs have tend to cluster around a relatively small number of possible values. Furthermore, the relationships between these values are the same on any level. For example, at any given level (from 80 to 85) you will find that most humanoid mobs have the same amount of HP; then there are some weaker mobs that have only 85% as much HP; bosses have 275% as much HP; and so on.

And finally, if you compare the results across levels, you will find that the amount of HP increases in a systematic manner, by 7.5% per level (relative to the HP of a level 80 mob).

So you can divide the mobs into several ‘types’ and you will find that the HP of a mob is then fully determined by its type and level; to compute it, you just have to take a certain base HP (a constant), multiply it by a fixed coefficient that depends only on the type, and then multiply it by another fixed coefficient that depends only on the level.

mob_HP = baseline_HP × type_coefficient × level_coefficient

As I mentioned above, the level coefficients are very simple: you simply increase the mob’s HP by 7.5% of its level-80 HP for each level above 80. Thus, for a level 80 mob the coefficient is 1, for 81 it’s 1.075, for 82 it’s 1.15, for 83 it’s 1.225, for 84 it’s 1.3 and for 85 it’s 1.375.

Mob types

The type coefficients will of course depend on which type you take as the baseline. The following lists shows the types along with their coefficients; I used the ‘normal’ type from the list below as the baseline as it seems to be the most common, and choosing it as the baseline also leads to the most elegant results (a 7.5% increment emerges again, as we’ll see).

  • Feeble (0.775): this type mostly contains animals, e.g. wolves and firebirds.
  • Weak (0.85): this type also mostly contains animals, e.g. snakes.
  • Normal (1.00): this is the most common type; in particular, nearly all the humanoid mobs fall into it.
  • Tough (1.70): twice as much HP as the ‘weak’ type; this type mostly includes big animals such as kappas and water buffalo.
  • Boss (2.75): as the name says, this type consists of boss mobs.

Note that the 7.5% increment appears here as well, just as it did for the level coefficients: feeble = normal − 3 × 7.5%, weak = normal − 2 × 7.5%, tough = 2 × weak.

There are a few other types that appear more rarely:

  • Double normal (2.00): horse archers in the Northern Grasslands.
  • Double tough (3.40): wild stallions in the Northern Grasslands.
  • Tough boss (3.57): 30% more HP than a regular boss; Scarred Ursa in the Northern Grasslands.
  • Double boss (5.50): Reanimated Mammoth in the Northern Grasslands.
  • Triple boss (8.25): Senior Warmonk in the Northern Grasslands.

The Senior Warmonk, in the southwestern part of Northern Grasslands, appears as either a level 80 or a level 81 version (it’s random). The level 81 version, with approximately 58400 HP, has the highest amount of HP I’ve seen on a solo mob in a solo playfield so far.

A few other anomalies I’ve noticed:

  • Baio the Guardian in Chosain is marked as a boss but has 30% less HP than a regular boss would. This almost puts him into the ‘double normal’ type.
  • Level 80 Wild Horses in NG have a type coefficient of 0.70 (i.e. another 7.5% step below the ‘feeble’ type); on the other hand, level 81 Wild Horses fit nicely into the ‘feeble’ type.
  • Level 82 Peasant Workers in Chosain have an anomalous type coefficient of 0.75.

Estimating the baseline HP

So far we’ve seen the coefficients that will appear in our formula for mob HP from the beginning of this post; but what about the baseline HP?

We’ve seen that this is nothing else than the HP of a level 80 normal-type mob. After killing numerous such mobs, the lowest estimate of their HP that I could find was 6587 HP.

Another approach is to take the HP of some other kind of mob and divide it by the coefficients (now that we’ve established them). For example, we can estimate the HP of the level 81 Senior Warmonk (I got 58440), divide it by 1.075 (its level coefficient) and by 8.25 (its type coefficient), and we get 6589 HP. These things seem to fit together pretty nicely, so I’ll stick to 6587 as my estimate of the baseline HP.

Finally, a table

Now we can plug this baseline HP into the above formula and obtain estimated amounts of HP for each combination of type and level. It turns out that the results match my empirical measurements (obtained by analyzing logs after killing various kinds of mobs) very nicely. If you move your mouse over a number, you should see examples of mobs with that amount of HP in the tooltip.

* The asterisk marks combinations of type and level for which I didn’t find any mobs. This occurs at level 82 because there are relatively few mobs at that level in Khitai: Northern Grasslands is mostly 80–81, Chosain and Kara Korum are mostly 83–84.

Comparison with old-world mobs

I haven’t yet explored the HP of old-world (i.e. pre-expansion) mobs thoroughly enough, but from what I’ve seen so far, there aren’t as many different types there; only the normal and boss types are present. The bosses have 2.75 times as much HP as normal mobs, same as in Khitai. The HP increases by 20% (of the level 80 value) for each level above 80 (as opposed to 7.5% in the case of Khitai mobs). The baseline HP is much lower than in Khitai.

The Breach and Forgotten City follow the old-world pattern as well, although some of the bosses there have an extra 50% HP (which pushes them to 19000 HP at level 80).

The Battle Commanders of Chosain

June 10, 2012 Leave a comment

Two raid mobs stand on the big battlefield west of Shaulun, one on each side: the Cheng-Ho Battle Commander and the Tamarin Battle Commander. They are surrounded by a few normal (solo) trash mobs and are pretty easy to kill; the only challenging part is getting a group of people interested in doing it 😛 They don’t have any special abilities; they hit pretty hard, but they are vulnerable to CCs, so they can even be solo tanked if enough people are CCing them. Each of them has approx. 2.2 million HP.

Incidentally, they are considered faction mobs, so if you are friendly to one of these two factions, you can’t attack its Battle Commander; but if someone else in your team starts the fight, the mob will become attackable by you in a few seconds as well, so you’ll still be able to participate in the fight normally. You needn’t worry about losing faction reputation as they don’t seem to be considered worth any more than a normal boss and it will be divided among all the people in your team anyway.

Their loot doesn’t seem to be terribly impressive; we killed them with a group of 8 people and got around 2k AA XP for each kill, each Battle Commander also dropped one weapon, one social helmet, and a few imperial insignia, patroller’s kits and esteem tokens to roll on.

According to both yg.com and the BeBot item database, it seems that the Cheng-Ho Battle Commander drops 8 weapons and the Tamarin Battle Commander drops 7 others. Their loot tables are complementary, and taken together they drop useful weapons (and shields; but no ammunition) for all classes. The weapons look nice and the stats seem pretty decent for blue items; but the Cheng-Ho weapons show the same silly preoccupation with immunity that is so characteristic of their armor sets as well.

Additionally, each of them also dropped one of these social hats. I don’t know if there are any other social items dropping from them; I didn’t find anything obvious along those lines in yg.com.
