Blood Bind

Seize one creature’s blood and lock its movement. The target must make a CON save or become restrained for the duration. While restrained, it takes 5d8 necrotic damage at the start of each of its turns. It repeats the save at the end of each turn, ending the effect on a success.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
