what kind, like buffers, or dmg?
and if it is dmg, don't you think we should be allowed more health, or AoE is only like 100dmg?
Haven't started developing any of it yet, so I don't really have any answers atm.
I can say that some of the first AoE stuff i plan to develop is Mage AoE (proximity to mage) buffs, that could add damage or accuracy or whatever.
The earliest damaging AoE projectiles i can envision will probably be Ranging related ('explosive arrows' equivalent).
