Binding

You grasp the wrist of an unconscious huge to a tiny creature with less than 5 hit points remaining and create a magical bind that holds its hands together, with similar binds appearing around its ankles and mouth. while bound, the creature cant speak, its speed is reduced to 10 feet, it cant fly if it could, and it can't move more than 60 feet away from the caster unless the caster allows it. when you cast this spell, set a code word in your mind. When you speak it, regardless of where you are, the creature is released and the spell ends. otherwise, the spell ends in 3 days.
