Dispel Good

(Player's Handbook v.3.5, p. 222)

Abjuration [Evil]
Level: Cleric 5, Disciple of Thrym 5, Nar Demonbinder 5, Death Master 5, Evil 5, Hades 5,

This spell functions like dispel evil, except that you are surrounded by dark, wavering, unholy energy, and the spell affects good creatures and spells rather than evil ones.
