I have discovered that culnivar’s claim puts the player back into human form when the rage value hits maximum rage, in my case this is 206 rage, I do not know if this is intended but with the wording of culnivar’s claim there is a line that reads "100% of mana converted to ward when you reach full mana, is it intended to work with rage? Should this even work while transformed?
I have also noticed that once you revert to human form it is literally impossible to go back to a transformation. You enter a transformation mode and instantly revert back to human form because you are forced at the maximum rage value due to the nature of transforming as a druid.
