Heal from <damage type or effect>: Some creatures are healed by certain types of spells or effects (for example, Flame or Stone). Creatures with this ability cannot be healed by carrier attacks, but can be healed by elemental packet attacks, by spells, by “Spell <effect>” or by “Arcane <effect>”. A creature that is “healed” by an effect is also immune to that effect in carrier attack form. For example, a zombie that is “Healed by Chaos” would be immune to the carrier attack “2 Chaos.” As noted in the “Defenses” section, anyone healed by something other than Healing or Chaos must state “Healed” when they regain Body Points from one of these unusual effects. Immune to <damage type or effect>: Many creatures have immunities to certain effects. Creatures must call “No Effect” when using this ability.
