"Efforts to increase the power of Dispel resulted in a power that, unfortunately, cannot be directed. Nonetheless, it is quite effective."Mass Dispel is a third-level Order Magic spell in Heroes of Might and Magic IV that costs five spell points and removes all spells from all targets.
The atomic bomb of spell negation. All spells (including illusions), for weal or woe, are erased from combat in one fell swoop. Similar to Armageddon, it is of particular use to the weaker hero who may find themselves snowed under by the power of a stronger spellcaster. Like its more discriminating counterpart, it also removes Guardian Angel from all heroes protected by a Potion of Immortality, making it truly a double-edged sword.
