Magic Defiance Undone

Magic defiance undone can make another wizard spell more potent: It pierces magic resistance and other abjurations that shield a target from spells. It even helps a wizard overcome creatures with effective saving throws against spells. Casting magic defiance undone wraps the spell a wizard casts the next round in its enchantment. Targets must then make two magic resistance checks to resist the offensive spell, then roll a saving throw for each check that fails.

For example, if Therdillion the Invoker casts magic defiance undone with a disintegrate spell at a creature from the outer planes with 50% magic resistance, the DM must roll twice to see if its magic resistance proves effective. If either roll fails, the spell gets through, forcing the creature to make a saving throw. If both magic resistance rolls fail to resist the spell, the creature must make two saving throws. Should it fail either one, the creature is disintegrated.

Spells such as anti-magic shell, spell turning, spell immunity, etc. function only 50% of the time +1% per level of the caster vs. a spell cast with magic defiance undone.
