Herb of Air

"A mysterious herb that grants the power to breath underwater when placed in the mouth. It is especially prized by those who live on the sea, and it has been fought over and zealously sought by sailors, pirates, and fishermen for many generations. It grows naturally in many different locations, but since beasts enjoy its flavor, ferocious and feral beasts are often found in significant numbers nearby. As a result, not just anyone can collect it and its value remains high on the open market."
