Generic, Text: Haemo-Puppetry

After 17th level, you have nigh on mastered the art of controlling others. It is especially effective when merged with your blood. If your blood enters another being with blood (as ruled by the DM) of one size class larger than you or smaller, they are considered to be under the effects of Blood Bending, until they succeed on a Constitution saving throw of your Haemomancy save DC + 2 or you lose concentration on your blood. You may concentrate on up to three creatures containing your blood or one with your blood and one without, though in this case the one without your blood rolls against your typical Haemomancy save DC. The creature(s) make(s) a new Constitution saving throw at the end of each turn. If you terminate the control early, you may deal 5d10 necrotic damage to the target. You lose control of a creature if it goes beyond 60 feet away from you. You may only forcibly terminate this effect and cause the associated damage a number of times equal to your Constitution Modifier, with a minimum of 1.
