Unstable air rune

The unstable air rune is a potential reward from the Motherlode Maw and potential item sold in the Travelling Merchant's Shop during the Travelling Merchant random event at the Deep Sea Fishing hub. When investigated, it grants the user 5,000 Runespan points, and it gets destroyed in the process.
