Breathing Reed

The Breathing Reed is an item that can be found in water chests. When equipped, a reed will appear above your character, making him/her able to breathe when the reed is above the water instead of themselves. It also causes breath to decrease more slowly. The downside to using it is the fact that you need to keep it equipped, so you can't fight, dig or do anything else when using it. Check the Ocean on both sides of the map.
