Blood Bound

A creature of your choice within sight range may be affected by frozen blood. The creature must succeed a Dexterity saving throw or become Restrained for the duration of the round + 2d8 cold damage.

The target also takes 1d6 + 1d4 damage on the next two turns if a heat source is not immediately present, and must make a Dexterity saving throw to see if it is still affected by the restrained condition.
