Wind Pipe

This 2-foot-long brass tube is 3 inches in diameter and is threaded so that additional lengths of ordinary tubing can be attached.

A wind pipe is a device built for pumping air into submerged or otherwise enclosed spaces. When activated, a flow of air equivalent to a moderate wind blows through the pipe. The intake end must be surrounded by air for the magic to work. Even if the space the air moves into has no outlet, the wind pipe provides circulation of the air magically.

Prerequisites: Craft Wondrous Item, favorable wind.

Cost to Create: 3,500 gp, 280 XP, 7 days.
