Slime for the Slime God!
Henzell says...
  1. Fills 8-10 squares (by flood fill from the target point -- this can be manipulated, as it won't fill a square that already has a cloud) with clouds doing cold damage. (Conjurations/Ice/Air 6). In 0.27, level 5 instead.
  2. kills things dead, but lasts for a long time after everything dies, so prepare to have a picnic waiting for it to clear.
  3. Sorbius: I imagine the dungeon is just hot as hell and the monsters are like, hell yeah AC! and then realise way to late what's really going on
