Strength Through Passion (Health Recovery) Galactic Challenge Feat

It would be nice to know what actually counts, I wasted way too much time trying to do this before eventually landing on DR Malak and BSF. Had to get about 10 drain life’s off with malak which was a nightmare because I also couldn’t kill anyone while doing it. A progress bar and some clarification as to what abilities do or don’t count would go a long way
