Energy Heal
A Monster Trait. Text from the Celestial Codex.
Description
Any effect or attack listed [in the parenthetical qualifier following the trait listing] will effect the creature as though it were a Heal spell, removing one wound or restoring a single point of Natural armor. If the qualifier listed describes an area, as in a Terrain effect or Fixed Enchantment, the creature gains the benefits of Regeneration as long as it remains there. The creature is Immune to any detrimental effects of the listed Qualifier. Monsters with this Trait that also possess an ability that could activate the Trait (Ex: a monster with Energy Heal (Flame) and the ability to cast Fireball) may not use their own abilities to Heal themselves.
Currently, the Hellhound is the only monster with this Trait.
