Blood Manipulation

You sap your own blood to create a floating mass of blood, forming a 1 cubic foot sludge within range. You can manipulate and move the blood as an action, making it change its shape, float to different positions, or interact with objects, such as pressing buttons, pulling levers, or carrying small items (up to 10 pounds).

Cost: To form the sludge, the caster takes 2 necrotic damage. 

You can choose to harden the blood by spending an action, in which case the health you spent is not regained. If you end the spell without hardening the blood or the time runs out, you regain the health spent. If the blood is destroyed by an enemy or If the blood mass moves farther than 60 feet away from you, you lose control of it, and the spell ends immediately, losing the ability to dispel it to regain the health. Once hardened, the blood becomes a solid object, holding its form, and can no longer be manipulated.

Cantrup Upgrade: At level 11 the sludge can be manipulated and hardened using a bonus action.
