Reaper

Reaper relies heavily on his ability to kill Droids when their HP is low, doing this ability early game in room with a bunch of droids will help immensely.

Abilities

 * Passive - Lose 25 max HP before the game starts.
 * [0/4] Steal Soul = All Droids take damage equal to 25% their max HP. Gain 5 Max HP for every droid killed this way.
 * [0/10] Dark Omen = Heal equal to the Droids you've killed with the Soul Steal ability.
