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 Shadow Clone 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, Shadow Clone has an armor class of 10 plus your spellcasting ability's modifier. The shadow clone's initiative in combat equals your initiative minus your initiative bonus. The Shadow Clone can be used to cast any spell the original caster has prepared, and shares the spell slots of the caster. Attacks against enemies that are aware it is an illusion deal half damage. 

If the blood used to cast the spell is self drawn, reduce your current hitpoints by 1.
