Cosmetic icon River Vial: Oil (Tool).png
Tool 17025
Rarity: Mythical

Auctioned from the estate of a brilliant but failed alchemist, these mystical vials have the power to transform liquid water into nearly any substance. However, a steady hand is required. The next item on the auction block was the greasy corpse of the sneezing thaumaturge himself. Vial art, indeed.
