You brandish the weapon used in the spell’s casting and make a melee weapon attack with it against one creature within 10 feet of you. On a hit, the target suffers the attack’s normal effects. On a miss, you make a second melee weapon attack with the same weapon against the target. On a hit, the target takes psychic damage equal to your spellcasting ability modifier, instead of the weapon’s normal damage.

The spell’s damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d8 psychic damage whether it was the first or second attack. This extra damage increases by 1d8 at 11th level (2d8) and 17th level (3d8).
