A percentual slow is OP, of course. Didn't thought that through. I changed it to a flat slow for now, since it's similar to a debuff aura (like Fiddle's innate). Also, the flat slow now needs Voidwings to operate.

While not stated in the stats or notes (forgot that, will edit the notes), she is intented to begin with sub-par defensive stats and movement speed when compared to other melee fighters. The passives gives her unique traits to compensate early, with the maxed passives softening the traditional curve of fighters towards mid-end game (where fighters begins to get outclassed by good carries, ally and enemy ones alike).
