This spell creates a bolt of divinely-gifted positive energy, healing those within its path and damaging undead. (The caster may designate which targets are healed.)
All creatures within the area are subject to the effects of the spell heal on a failed Fortitude save. In addition, effected undead in the area whose HD are one-half or less of the caster level are destroyed, instead of being reduced to 1d4 hp. Evil outsiders are ignored by the spell's healing effects, unless they are of the Undead type.
In addition, all evil outsiders in the area must succeed at a Will save or be banished (see banish seed.) This capacity of the spell has no effect on evil outsiders of greater than 22 HD.
In order to power this spell, the caster must sacrifice 8 turning attempts, and endure 24d6 backlash damage.
