Echoing Strike

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise, the spell fails. On a hit, the target suffers the attack's normal effects, and a faint spectral echo of your weapon appears hovering over its head. If you hit the target with a weapon attack before the end of your next turn, it immediately takes 1d4 force damage, and the spell ends.

This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
