Daring Smite

While you are concentrating on this spell, you have disadvantage on all attack rolls. The first time you hit a creature with a melee weapon attack during the spell’s duration, your weapon channels you inner confidence and strikes down with absolute might, dealing an extra 3d8 force damage to the target.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the extra damage increases by 1d8 for each slot.
