Barriss' Unique is bugged.

7AnimalMother

Her unique is giving heal on crit even AFTER she dies. I'm assuming this is not WAI because no other characters uniques appear to give any lasting impact after their deaths...

A lot of the leader abilities last after death. I wouldn't be surprised if there are other special abilities that last, or if barriss's is like that to make her more apealinh over another jedi (since healing is the ONLY thing she is good for)

7AnimalMother

This isn't her leader ability...
