Wand of Bubbles

As an action you can cause harmless bubbles to
stream from the tip of this wand.
1/day - Air Bubble: As a reaction, you can create
a magical bubble of air around a willing target's
head or an object of similar size. The bubble lasts
for one hour and allows the target to breathe
freely underwater or in similar airless
environments. The spell ends if the target takes
any piercing damage, popping the bubble.
