But a weakness that made troops require mana to be built would be nice :P.

Sounds like a good plan.
Its also a good thing that your undead exploding spell only grants the ability to explode otherwise it would be suicide to use it as an undead faction :P.
Ya my custom undead faction has the ability added so that they can be necromancers/gravelords :P too bad that the there is a 5 percent chance of doing a random action if i follow the lichpath of the gravelord is it possible you could replace that annoying debuff with another less game breaking one since there are some useful abilities in that tree even for an undead faction since the buff spells effect the whole faction :P.
Could you make it so that to get the trait to become a lich you can't be an undead already so that the ai so to get the trait as an undead faction or could you tweak it so that if the ai is already undead they become a more powerful undead?
