Okay, I know this sounds retarded, but I tried to even this over and over. It's impossible.
Blizz-abs should have kamikaze enemies. (Suicide bombers) or something like that. You know, enemies that run after you and after they touch they, they explode.
Like under the "enemy-type" options, you can check kamikaze. That would not only be awesome and hilarious, but interesting to see. T_T Like I said, I though I could even this at first, but I didn't succeed.
