Carry the black torch! Rouse the idle dead!
Henzell says...
  1. It has a [1/5 in 0.33] or [(15 to 45)%, scaling with Evocations skill in 0.34] chance of refunding MP, but gives ongoing -Wiz (equivalent to 2.5 levels of wild magic). Does nothing for Djinni.
  2. (Before 0.30) Whenever you successfully cast a spell, gives an evo/54 chance of doing something. There's a 1/(evo - cost) chance of backfiring (confuse or int drain), but your spent MP are fully refunded otherwise. Does stack with wucad mu. Does nothing for djinn, of course.
  3. For about a month in 0.30-a, gave -Cast instead of confusing when it backfired.
