Your hand fades into intangible shadow, slipping into the realm of shadowstuff. Make a melee spell attack against a creature's shadow, which extends from the creature 5 feet in any given direction, and has an AC equal to 10 + the creature's Dexterity modifier.
On a hit, the creature's shadow becomes just barely tangible; for 1d4 rounds, ending on your initiative at the end of your turn, the creature's shadow is able to be targeted by weapon and spell attacks. The shadow is immune to area of effect spells, but spells and attacks that directly target it can find purchase, dealing the same damage to the creature. The shadow is immune to all conditions, and thus cannot transfer them to the owner of the shadow.
The shadow is immune to necrotic and poison damage, resistant to acid, cold, fire, lightning, thunder, and nonmagical weapon attacks, and vulnerability to radiant damage. Additionally, ranged attacks against the shadow have disadvantage.
