This short ritual binds a single byakhee to carry out a task directed by the caster. Any byakhee within range that were recently conjured by the call byakhee ritual calmly listens to the ritual tune of bind byakhee until the player makes an error, at which point all byakhee present are free to attack the caster or do as they wish unless bound by another casting of this ritual. This ritual bypasses a byakhee’s usual immunity to mind-affecting effects.
