Eldritch Blade

A weapon you Wield becomes wreathed in crackling energy. Make a melee spell attack against a creature Within your weapon's reach. You have advantage on the attack roll if the target is under the effect of a curse.

On a hit, the target suffers force damage equal to your weapon's damage dice roll. At 5th level the target takes an additional 1d10 force damage. This spell's damage increases by 1d10 when you reach 11th level (2d10) and 17th level (3d10).
