Bloody Claw

Warm blood seeps from your fingernails as you swipe and roar, conjuring spectral claws from each of your digits. Make a melee spell attack against the target. When casting this spell with your own blood, make a DC 10 (Constitution) saving throw or suffer damage equal to its spell level. If this spell is cast with blood from a creature or drawn from you safely, you do not make a saving throw.

Bloody Claw: On a hit, the target takes 4d4 slashing and 1d4 piercing damage. Target creatures hit must also succeed a spell save DC (Constitution) saving throw or begin to Bleed.

Bleed: On a failed Constitution saving throw, target suffers damage every turn starting at 1 and increasing by 1 every subsequent turn. Constructs, Elementals, Plants, and Undead are not affected Bleed. This affect can be removed by healing.
