Protean Glass

Protean Glass is a rare potion bag for the Alchemist Class obtained from the City of Shifting Waters Dungeon. It can be turned into a Celsian Alchemist's Bag in the City of Shifting Waters Rare Trader in the Dungeon Lobby.

Obtaining

Protean Glass can be purchased from the City of Shifting Waters Rare Trader in the Dungeon Lobby for 2 Shifting Fragments.

Or alternatively purchased with a Celsian Alchemist's Bag and 2 Shifting Fragments. Note that this is used for carrying over infusions.

"The glass itself is impossibly shaped, twisting into its own form, yet preserving the liquid within all the same."

Protean Glass along with most of the Alchemy Bags, is the only Rare in the King's Valley and the Celsian Isles to cost 2 Fragments instead of the usual 4. This however becomes normal in the Architect's Ring.
Unlike the other City of Shifting Waters Rares, Protean Glass is only obtainable through the Rare Trader.
