Space Dementia Wizard Achievement
What is the easiest way to earn the Space Dementia achievement?
Space Dementia
Damage 30 enemies with one Black Hole cast.
Best Answer
The easiest way would be to go to either campaign, beginning of Act IV and face Iskatu, wait for enough enemies to spawn around you and use black hole then.
Another easy way is to go to Act I, The Weeping Hollow and find few of Retching Cadavar mobs that spawn zombies (do not confuse with Deathspitters, they have same model) and run around them until there's enough zombies spawned and then use black hole.
