You summon a burst of energy that harms all living creatures that have a soul. Thus, inanimate objects suffer no damage, but neither do undead, constructs, plants, or outsiders. Those affected take 1d6 points of damage per level (to a maximum of 10d6). This spell was developed by mages in charge of defending the citadel of their king against invaders—they did not want to damage their own defenses or the structure itself. Soul burst is also favored among necromancers who wish to damage their enemies but not their own undead guardians. Material Component: A crushed feather.
