They must make a Constitution saving throw. On a failure, they take 4d6 necrotic damage and If the creature is casting a spell of 3th level or lower, its spell fails and has no effect. If it is casting a spell of 4th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell fails and has no effect.
At higher levels: When you cast this spell using a spell slot of 6th level or higher, the interrupted spell has no effect if its level is less than or equal to the 2 levels down of the spell slot you used. The damage increases by 2d6 for every level spell slot Available for: Sorcerer, Wizard, Warlock
