A town in ruins
10 Air Crystals
These alchemical shards can be chewed for air
As a standard action, a player may put a handful of air crystals in their mouth. For 1 minute, they may chew them for air as a free action. They are non-toxic but must be swallowed in order to speak or cast spells with somatic components (ending the 1 minute duration).
After assisting the dark aberration, the PCs are rewarded with a variety of substances, including these.
