Thaednu's Blood Letting

You call forth the blood of one living creature within 60ft of you, and form it into a sphere hovering just above your outstretched hand. The target must have open wounds, and any creature without blood is unaffected by this spell (i.e. undead, constructs, etc.). The target must succeed at a Constitution saving throw, or they take 3d10 damage and gain one point of exhaustion every round. The target can repeat the saving throw at the end of each of your turns after the first, ending any further effects on itself on a success.

Exhaustion Effect-

1. Disadvantage on Ability Checks
2. Speed halved
3. Disadvantage on Attack rolls and Saving Throws
4. Hit point maximum halved
5. Speed reduced to 0
6. Death
