School transmutation; Level alchemist 2, sorcerer/wizard 3
Casting Time 1 full round
Components V, S (see below)
Duration 1 min./level
Upon the casting of this spell, you may place a single magical potion or alchemical extract within your mouth. The vial shrinks into a small place between your teeth and is held there until you choose to activate it as a swift action, at which point you suffer 1 point of damage from the glass shattering.
At this time, the potion or extract takes full effect. You may only have one bottlemouth in effect at any time. If the duration ends or it is dispelled, the potion or extract immediately grows to full size, causing 1d6 points of damage and interfering with speech and verbal components until removed.
