Using a Ferrofluid Flask restores Nephtoglobin as well as Health.
Amber
Potent Concoction is an Amber that makes your Ferrofluid Flask do double duty. Once it is equipped in an Amber Slot at a Lantern, drinking from the flask brings back Nephtoglobin alongside the Health it already restores. That turns a single heal into a top-up of both resources, so a flask spent mid-fight does more for you. The Amber has 3 ranks, and picking up a further copy raises it by one rank.
One copy sits in a chest in the Valley of Ashes, with Quarry as the nearest Lantern. Another copy is in the Fortress, inside a trapped chest close to the Ramparts Lantern, so be ready for the trap when you open it. Each copy you pick up lifts the Amber one rank, which makes both detours worth taking.
