Spring Water from the Forest of Echoes

Stored in a bottle, the liquid appears as a clear, blue water. Its origin lies in the Forest of Echoes, a location set within the Glacier Dungeon, and it is catalogued among the consumable items of the series. Though unremarkable to the eye, the water holds rare purifying properties that give it far greater value than its plain appearance suggests.

The water's defining trait is a powerful capacity to cleanse poisons from anything it touches, whether swallowed or applied directly to the body. Its detoxifying strength is extreme: it can purge corrupted blood from a Demon Monarch and even drive out the influence an Apostle holds over those it has enslaved or inhabited. Beyond this neutralizing role, the liquid is one of the components required to brew the Holy Water of Life, a remedy of considerable importance.

During the Retesting Rank Arc, Sung Jinwoo claimed the water after overcoming Metus on the Demon Castle's seventy-fifth floor. At first he gave it little thought, but the moment he received the recipe for the Holy Water of Life he recognized its purpose: a means to treat his mother, Park Kyung-Hye, of her Eternal Slumber. Much later, in the Glacier Dungeon Arc of Solo Leveling: Ragnarok, Sung Suho located the spring itself and used the water to liberate Thomas Andre from the Apostle that had taken hold of him. With the Ice Elves' consent, the Scavenger Guild then began extracting the spring water as a sellable Detox Potion, though entry was limited to Cha Hae-In and Suho, prompting tense bargaining between the Scavenger Guild and Ahjin Soft over the Sung family's share of the resulting profits.
