Dispelling Smite

The next time you hit with a melee weapon attack during this spell’s duration, your attack deals an extra 1d8 lightning damage. If the creature has any spells cast on them,  any spells of 2nd level or lower on the target ends. For each spell of 3rd level or higher on the target, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a successful check, the spell ends.
