Path of Exile Allflame Lanterns
Allflame Lanterns are what allow you to survive underwater during Lost Charts. Each Path of Exile Lost Chart expedition provides a limited number of Lanterns, which create safe oxygen bubbles. They allow you to explore, fight enemies, and collect loot. The first Lantern is placed automatically, and you must continue placing new Lanterns at the edge of each bubble to expand your path across the sea floor.
Whenever you place an Allflame Lantern, any glowing coral within its range is automatically collected as Dead Man’s Sulphur, one of the league’s main crafting resources. After placing your final Lantern, all Lanterns begin to flicker, and their safe zones start collapsing. At that point, you must quickly return to the Bathysphere and escape.

You can obtain Lost Charts in PoE by finding Cursed Treasure throughout Wraeclast and in maps. Each treasure is guarded by groups of enemies, such as undead, corsairs, or sea creatures.
