Animate Blood

You cut yourself and unleash three drops of blood that you animate like familiar spirits. The blood resembles any ordinary drop of blood, except it can roll and bounce on the ground. A blood drop has an AC 15 and 1 hit point. While you maintain concentration, you can command either each of your blood drops as an action, or one as a bonus action. Each command you give can be one of the following:

• The blood drop moves 30 feet.
• You can see and hear as though you occupied the blood drop's space. During this time, you are blind and deaf in regard to your own senses. 
• Make a melee attack against 1 living creature within 5 feet of the drop. A successful attack deals 4d10 necrotic damage and destroys the drop of blood. 

Any drop of blood that leaves the spell's range becomes an inert and normal drop of blood. While your blood drops are active, any time your blood drops are affected by a spell attack, you suffer the ill effects of the spell rather than the blood drop. Your blood drops count as you for the purposes of spells with a range of touch, allowing you to use those spells to target creatures adjacent to any of your blood drops. 

At Higher Levels: When you cast this spell using a spell slot of 7th level or higher, you create one additional drop of blood for each slot level above 6th.
