As the title states, the bestial nature enhancement in the Nature's Warrior tree is completely broken. The will save penalties stack (despite the fact that the total penalty is supposed to be -2), and the penalty doesn't disappear upon toggling the stance off. I literally had to LR last night to completely get rid of the penalty because nothing else worked. Luckily, I still had the free lesser heart from forever ago, but the fact that an enhancement that has been around for almost two years is so broken is more than a little frustrating. Please either fix it or replace it with something more useful.
