As the dispel magic spell, except that the bonus on the dispel check is +15, not the caster level. Additionally, greater dispel magic has a chance to dispel any effect that remove curse can remove, even if dispel magic can’t dispel that effect.
Material Component: Various rare incenses, herbs, and reagents (purchase DC 20).
Backlash: Caster takes 4d6 points of damage.
Failure: Augment. One characteristic of the magical effect targeted (area, range, duration, etc.) doubles. The target spell might deal twice as much damage or a curse might bestow twice the penalty, for example. The GM determines which aspect of the target spell is so augmented.
