Bubblephone

As part of the action you use to cast this spell, you blow clear and iridescent bubbles roughly the size of a Small creature, which move over and gently engulf the head of any number of willing creatures you can see (including yourself) within the spells range. Each bubble has an AC of 10 and immediately burst if it takes any damage, or the spell ends.

Creatures must remain within 30 feet of the caster, or lose all benefits of this spell for the remainder of its duration.

While the bubble remains, any verbal sounds uttered by the chosen creatures can't be heard except by those under the effect of this spell.
