The Burning Monolith: Path of Exile 2's Endgame Challenge
The Burning Monolith, a unique map location in Path of Exile 2's Atlas of Worlds, resembles the Realmgate but presents a significantly greater challenge. Accessing it requires three Crisis Fragments, each obtained by conquering a Citadel—an exceptionally rare and difficult map node.
Unlocking the Arbiter of Ash
The Burning Monolith is the lair of the Arbiter of Ash, the game's most formidable pinnacle boss. Your first attempt to activate the Monolith's door initiates "The Pinnacle of Flame" quest, comprising three sub-quests: Ezomyte Infiltration (Iron Citadel), Faridun Foray (Copper Citadel), and Vaal Incursion (Stone Citadel). Successfully completing these Citadels yields the three necessary Crisis Fragments. Combine them at the Monolith's altar to unlock the Arbiter of Ash encounter. Prepare a powerful build; this boss boasts devastating attacks and colossal health.
Locating the Elusive Citadels
Path of Exile 2 features three Citadels: Iron, Copper, and Stone, each guarded by a unique boss. The Crisis Fragment for each Citadel is obtained upon defeating its boss. The primary difficulty lies in their rarity.
Citadels are one-time attempts. The Atlas is procedurally generated, making Citadel locations unpredictable. While no guaranteed method exists, community strategies include:
Citadel hunting is a late-game activity, best undertaken with a fully optimized build.
Purchasing Crisis Fragments
As an alternative to the arduous Citadel hunt, Crisis Fragments can be purchased via the trading website or Currency Exchange. However, their rarity often commands a high price. Weigh the time investment against the cost before making your decision.
