Dominate Shadows

You murmur a command to compel any visible shadow to attack whatever creature is casting that shadow. The shadow wraps itself around that creature, creating a dark, shimmering, vapor-like aura around it, and does 1D6 necrotic damage per turn. Additionally, the creature automatically fails any saving throws against shadow or necrotic damage, and gains disadvantage on any saving throws against radiant damage. The targeted creature can move up to a maximum of 15 feet per turn for the duration of the spell.

A targeted creature may attempt a constitution saving throw equal to the spell caster's spell attack to regain control of their shadow for the duration of this spell.

The spell caster can cast a number of creatures equal to their level. The creatures' shadows must be visible to spell caster. This spell does not work on vampires or any spectral creature that does not cast a shadow, nor does it work in full darkness.
