Dispel Magic

This spell can be used to end ongoing spells or similar magical effects cast on a creature or object, or to end such effects within a cubic area 20' on a side. The caster must choose whether to dispel magic on a creature or object, or to affect an area. If dispel magic is targeted at a creature, all spell effects (including ongoing potion effects) may be canceled. If cast upon an area, all such effects within the area may be canceled. Any spell or effect having a caster level equal to or less than the dispel magic caster's level is ended automatically. Those created by higher level casters might not be canceled; there is a 5% chance the dispel magic will fail for each level the spell effect exceeds the caster level. For example, a 10th level caster dispelling magic created by a 14th level caster has a 20% chance of failure. Some spells cannot be ended by dispel magic; this specifically includes any curse, including those created by bestow curse (the reverse of remove curse) as well as by cursed items.
