Whirlpool Maw (elemental augmentation)
Aura moderate conjuration; CL 7th
Slot none; Price 19,000 gp; Weight
Description
The user’s mouth and throat are linked to an extradimensional whirlpool of water. As a full-round action, the user can swallow an adjacent unattended object up to 10 cubic feet in size. The swallowed object causes no damage to the user and has no weight; while it is swallowed, the object is stored within a nondimensional space similar to that of a bag of holding. The user can spend a full-round action to retrieve the object, which is unharmed except for being waterlogged. The recipient can store only one item at a time in his maw. If the whirlpool maw’s effect is suppressed or dispelled, the stored item appears instantly. The recipient constantly dribbles water when his mouth is open and halves the duration he can normally hold his breath.

This elemental augmentation cannot be applied to a creature without a mouth.
