Crystal of Air Bubble Uncommon As an action a creature can press this crystal to their sternum, or the sternum of a willing creature withing 5ft and speak a power word.
Upon doing so the crystal sticks for 1 minute. For this duration it creates a spectral globe around the head of the creature. The globe is filled with fresh air that lasts until the spell ends. If the creature has more than one head, the globe of air appears around only one of its heads (which is all the creature needs to avoid suffocation, assuming that all its heads share the same respiratory system).
