Valery's Doppelganger

As you mutter the verbal components of the spell, the blood on your hands sizzles away to smoke, which manifests into a copy of yourself created from smoke and shadow in an unoccupied space with 30 ft that you can see. Upon creation, roll d4's equal to the level you cast the spell at for the clone's hitpoints. Any creature that has sight of the creation of the Doppelganger automatically knows it is an illusion, and all other creatures that encounter it must make a perception check that beats your spellcasting DC to know it is an illusion.

In combat, Doppelganger has an armor class of 10 plus your spellcasting ability's modifier. The doppelganger's initiative in combat equals your initiative minus your initiative bonus. The Doppelganger can be used to cast any spell of 5th level or less that the original caster has prepared, and shares the spell slots of the caster. The Doppelganger is unable to attack or deal damage to any creatures in initiative, their use is strictly utility. The caster also receives the memories of their Doppelganger after they are destroyed.

When casted as a 3rd level spell or higher the caster can create an additional Doppelganger, to a maximum of two.
