Shared Vitality: The animal companions you bind have hit dice no lower than your level, even if they normally have far fewer. Thus, a 2 hit die beast bound by a 7th level Beastmaster would have 7 hit dice while it remained bound. Its hit bonus can’t be less than half its hit dice, rounded up. A Beastmaster can stabilize a Mortally Wounded companion by Committing Effort for the scene as an Instant action.
