Burning Blood

Select a creature with blood. For the duration, it must make a Constitution saving throw at the start of each of its turns. If it fails, it takes 1d8 Acid, Fire and Poison damage, and can only move, losing its reaction, action and bonus action until its next turn. If it succeeds, it only takes the caster's choice of the Acid, Fire or Poison damage. Succeeding on the saving throw does not end this effect.
