Twilight Reflection

You tap into the earthly essence of a humanoid of a CR of your level or lower, that you can see within range, and attempt to split its being in two, the target must make a Constitution saving throw. On a success, the target take 4d12 necrotic damage and the spell ends. On a failure, the target takes 4d12 necrotic damage, and pieces of its shadow melt away.

These wisps of shadow then coalesce as all cruel and wicked thoughts of the target gain physical form, as a dark clone of ash grey skin tone and a near-transparent visage appears at any point within 20 feet of them. This clone has all of the physical and mental stats of the target, has the same number of maximum hit points, and carries copies of all their non-magical items, which disappear if removed from their body. The clone follows your verbal commands, if given no command it attacks the target of the spell relentlessly.

The clone can't cast spells or use magic items, and can only attack once per turn, though it can use any unique racial or class ability the target has, such as a Rogue's Sneak Attack or a Halfling's Luck, as well as any feat the target has. The clone is immune to being frightened, and has resistance to necrotic and psychic damage. If the clone takes psychic damage, the original target of this spell takes half that amount. If the clone or the target of the spell are reduced to 0 hit points, the spell ends and the shadows of its form melt away, flowing back into the target.
