Blood Manipulation (5e Spell)
From D&D Wiki
|V, S, M (a silver needle and a small vial of the target's blood)
|Concentration, up to 1 hour
After ritually drawing blood from a creature within range, you gain control of its body. The spell fails if the target doesn't have blood, such as a construct, ooze, or plant.
For the duration, you can force the target to make a Constitution saving throw at the start of each of its turns as you attempt to control its actions. On a failed save, you control the target and can make it move and take actions for that turn; you can't make a creature cast spells or speak this way (although you can prevent it from doing either), and the target is conscious and aware of its surroundings while being controlled. On a successful save, the target takes its turn as normal. Additionally, whenever the target attempts to move or to take an action, you can use your reaction to force it to make a Constitution saving throw; on a failed save, the target is unable to move until the start of its next turn or it loses that action, respectively.
As an action, you can purge the target's bloodstream. The target makes a Constitution saving throw, taking 10d10 necrotic damage on a failed save or half as much on a successful one. The spell then ends.
At Higher Levels. When you cast this spell using a 9th-level spell slot, it doesn't require concentration.
