Disrupt Spell

You attempt to interrupt a creature in the process of casting a spell or intercept a ranged spell targeting you. You and the caster both make opposed Arcana skill checks. If you win the opposed check by a margin of 5 or less, the casting of the spell fails or the effects of the spell targeting you dissipate before hitting you, but the caster retains the spell slot used to cast the spell. If you succeed by 6 or more, the spell slot is lost. If you lose the opposed check by 5 or less, the spell goes off as normal, but there is no additional effect. If you lose the check by 6 or more, the spell goes off as normal and additionally, you lose your reaction on your next turn.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you gain an additional +1 to the opposed Arcana check for each spell slot above 3rd used.
