 * description	= Allows casting a more powerful version of the Dismissal spell on multiple targets. A successful Will save negates this effect. (DC = spell's save DC - creature's Hit Die + caster level.) In addition banishment deals 1d3+3 untyped damage per caster level to all targets on a successful will save.
 * notes         = This spell is only of use against Extraplanar creatures. It has no effect on other creatures - they are immune to both the instakill effect and the untyped damage. The instakill effect also does not work on Orange (on Epic Hard or above), Red, or Purple named monsters, although it is unaffected by Deathblock.
