You breathe deeply. The water is cool in your chest.

The transmuted creatures can breathe water freely. Divide the duration evenly among all the creatures you touch. When this spell’s duration ends, its subjects do not instantly lose its benefits. Instead, the ability to breathe water lingers for 1d6 minutes (roll secretly for each subject).

The spell does not make creatures unable to breathe air.

Augmentation:
If you cast this as a tier 4 spell, its duration is doubled.
