Any possibility of those charges at higher levels (7?) resetting each encounter? There already are such abilities.
3-5 Extra Action attacks per encounter would IMO make a Warpriest juicy, yet far from OP. For Gods sake - BARDS get TWO attacks!
Unfortunately not. I know it's still weak, just less pathetically so. The class still peaks at level 6 martially. They still get their first spell that can do serious damage at level 9. It used to get extra attack at level 5 in early versions of the mod, but not anymore.
I'm planning on combining it with a few modded items (mostly gear) for some better early spells. It will be worse than a light cleric still, just playable. You'll have to do the same for a balanced war cleric unfortunately
