Anti-Coagulation

Choose a target within range that you can see. A large cut opens up on the target; they must make a Constitution save or take 5d12 slashing damage, and have an open wound that fails to properly close as their blood cannot properly clot. On a success they take half damage and they do not receive the wound.

While the wound is bleeding, the target takes another 2d12 bleeding from the wound at the start of their turn, and all weapon attacks deal an addition 1d12 damage. They can attempt another Constitution save at the end of their turn; the wound properly stops bleeding on a success, and the spell ends.
