...come to think of it though, in DOS such teleporting enemy would not even be a complete cheese (with your only option to buff the frontliners to the brim and hope they have enough healing potions). you could, for instance, lure him away from his mobs, accept the loss of your GC, then telekinesis-lock him with an unbreakable chest that you were prudent enough to carry with you, and slowly kill with arrows through a thin opening that's just enough to give you a LoS.
