Blood Bending [HEHO Content]

You attempt to control the blood in a creature you can see within range in order to bend it to your will and force the creature to move accordingly.
This ability has no effect on creatures without blood such as Undead or Constructs.
It must succeed on a Constitution Saving Throw or be Dominated by you for the duration.

While the creature is Dominated by you, ethereal puppet strings attaching to their veins will appear visible to the caster and no one else. This connection lasts the duration of the spell based on the level cast as long as you are both on the same plane of existence and you are both conscious. You can use this tether to use your Action to move your hands and take total and precise control of the target. Until the end of your next turn, the creature takes only the actions you choose, and doesn't do anything that you don't allow it to do. It has Disadvantage on all DEX and STR Saving Throws during the spell's duration. During this time you can also cause the creature to use a reaction, but this requires you to use your own reaction as well. If the creature isn't given a direction, it simply defends and preserves itself to the best of its ability.

Each time the target takes damage and loses blood, it makes a new Constitution Saving Throw against the spell. If the saving throw succeeds, the spell ends.
If the target is below 50% hitpoints, it makes its Constitution Saving Throws with Disadvantage.

At Higher Levels.
