Duration Instantaneous

You attempt to interrupt a creature casting a spell. If the creature is casting a spell of 3rd level or lower, its spell fails and has no effect. If it's a spell of 4th level or higher, make a check using your spellcasting ability. The DC is 10 + the spell's level. On a success, the spell is interrupted.

At Higher Levels: The interrupted spell has no effect if its level is less than or equal to the level of the spell slot you used.
