Strength through Authority

As a bonus action, you can call upon creatures to demonstrate their loyalty to you and your cause. You and up to eight other creatures that can see or hear you can volunteer to be temporarily bonded together; if more volunteer, you intuitively choose which eight. Then, if at least one creature volunteers, choose yourself or one of those creatures to be the focus of the bond.

Each creature in the bond gains temporary hit points equal to your level plus your Intelligence, Wisdom, or Charisma modifier. These temporary hit points last up to one minute.

For the next one minute, whenever the person who is the focus of the bond takes damage or fails a saving throw , you are aware of this and can choose one of the creatures bonded to it (including yourself) to be ‘martyred.’ You then transfer the damage or the effect of the failed saving throw to the martyr, ignoring any resistances or immunities they might have. After someone serves as a martyr this way, the bond ends, but the temporary hit points persist.

After you use this ability, you cannot use it again until you complete a long rest.
