Karma's new passive
karma current passive isn't really a fun passive at all. if karma was a newly released champ her passive would be tied to her ult and given an interesting passive. unlike lulu or many other utility mages she has no game changing ult or really anything to make up for the lack of ult.

new passive gathering fire. whenever karma deals dmg with an ability or blocks dmg with shield she gains a stack of gathering fire. at 10 stack she gain an additional charge of mantra, up to a max of 3 charges. cannot mantra the same ability within 6 seconds or when you mantra the same ability twice karma is silenced for 2 sec (this will separate the good karmas from the great karmas)). charges decay while out of combat.
