Dispel Magic
Dispel magic has a base chance of 50% permanently to negate magic—both the magical properties of potions and the ongoing effects of certain spells. All spell effects and relevant items within the stated area of effect are subject to dispelling. Permanent magical items are not disenchanted by the spell, with the exception of potions, which are treated as 12th level for purposes of resolution. However, even a permanently enchanted item must make a saving throw or become nonoperational for one round. Any spells in the process of being cast in the spell’s area of effect will be lost, and any ongoing spell effects (such as invisibility) will be dispelled.
With respect to each potion, casting, or ongoing spell effect, the base chance of successful dispelling is increased 5% for every level by which the caster’s level exceeds the caster level of the potion, the casting, or the spell effect. The base chance is conversely reduced by 2% per level of difference if the caster is lower level than the caster of the magic to be dispelled. The spell will automatically negate the caster’s own spells if it is used for this purpose or if the caster has previously cast a spell into the same area.
