Second Wind

Second Wind is a magic item (ring) of common rarity.

Summon this item

Describe it your way — Second Wind is already filled in.

This plain, copper band holds a clear, spherical crystal. When you run out of breath or are choking, you can use a reaction to activate the ring. The crystal shatters and air fills your lungs, allowing you to continue to hold your breath for a number of minutes equal to 1 + your Constitution modifier (minimum 30 seconds). A shattered crystal magically reforms at the next dawn.
