More like consuming troll, how many times we have been killed by these mobs. Good clearing spectres, they'r projectiles off screen hard. Two big problems with these spectres: 1. they have reverse point blank same as Wretched defilers, meaning they deal less damage the closer they are to enemy so positioning is key, second problem they are too squishy, in this map run 1 ice nova took half of hp of 3 spectres, they can do regular harbingers, but stay away from boss harbingers. So overall a mixed bag.
