Echoing Blows

You conjure a spectral warrior resembling the figurine used as a material for the spell that hovers behind a willing creature you can see within 60 feet of you. Whenever the creature hits a creature with a melee weapon or spell attack, the creature strikes the target as well, dealing an additional 1d8 + your spellcasting modifier force damage.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for every two slot levels above 5th.
