Heres what I figured out to make these monkeys more annoying...
AMBUSHPREDATOR - Now you won't see them coming at you...
EQUIPS - Should make them equip gear they pick up, not sure though...
FREQUENCY - Make this higher and they appear more then you would wish...
LIKES_FIGHTING - Should make them stay around longer when you attempt to drive them away...
FLEEQUICK - Just to make the above one less, well deadly, should make them flee when you start to kick a good percentage of them around...
NARROW - If they pick up any Gobbo gear this should make them able to equip it... I think...
MISCHIEVIOUS - Levers where they can reach easily might be a bad idea...
SLOW_LEARNER - Like the Tag can learn but supposedly at a slower pace. Imagine the Monkey that took down your champ one year got away then came back the next stronger/smarter then the last...
Tag not sure about...
TRIGGERABLE_GROUP - Not sure what this does, at first it I thought that it makes more spawn when you trigger them into attacking or something but not sure, anyone knows what it is, I see it on all the vermin...
For an extra thought...
UTTERANCES - If I am not mistaken, this means that they should be able to get names right.
Well thats what i have thought off, but then again, perhaps this is too much, once started a Human City, and they nearly got wiped out by a swarm of Macaques group of around 7 or so just making a beeline for my wagon, Luckily I make two of my starting Umans have axes and the Axeman skill at base level...
