@ShuiMienLung Grab it while it`s still fresh
I recommend this mod to all KB fans, it`s really interesting, with lots new ideas.
As for chargers/rage drain it works after 20(25turn for hero fights) but wont give you any rage so what rage you accumulated up until that turn that`s amount you`ll have to manage with. Same goes for mana, after 20/25 turn no more mana regen, no matter what items/skills you have. You`r hero and his army gets tired after that and just stop gaining mana/rage
