'ABSOLUTE ZERO' Syntax: cast 'absolute zero' This spell plunges the temperature of the room where it is cast to the freezing point, increasing the effect of all melee freezing attacks and reducing the lethality of all fire damage on the necromancer's party. While developed to help shield the zombie army from trivial destruction by large fireballs, a useful side-effect of this spell is that it also freezes the black torrent spell, so that it instead deals weakening ice damage.
