Silver Cord Binding

Choose up to three willing creatures you can see within range. For the duration, they are bound by silver cords. While at least one bound creature is conscious, each bound creature has advantage on saving throws against charm, possession, banishment, magical sleep, unwilling teleportation, and effects that displace the soul. Once per round, when a bound creature takes psychic damage, another bound creature may use its reaction to take half that damage instead.

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