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 a Realmgate but presents a significantly greater challenge. Accessing it requires three Crisis Fragments, each obtained by conquering a Citadel – exceptionally rare and difficult map nodes.
Unlocking the Arbiter of Ash
The Burning Monolith serves as the arena for the endgame pinnacle boss, the Arbiter of Ash. Attempting 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 these fragments at the Monolith's altar to unlock the Arbiter of Ash encounter. Prepare a powerful build; the Arbiter of Ash is the game's toughest pinnacle boss, boasting immense health and devastating attacks.
The Citadel Hunt
Path of Exile 2 features three Citadels – Iron, Copper, and Stone – each guarded by a unique boss. Defeating these bosses grants the corresponding Crisis Fragment. The primary difficulty lies in locating the Citadels themselves.
Citadel attempts are one-time only. Their placement on the randomly generated Atlas is unpredictable. Community observations suggest these strategies, though success isn't guaranteed:
- Directional Progression: Choose a direction on the Atlas and explore systematically. Unlock Towers for a broader view.
- Corruption Tracking: Focus on corrupted nodes at the Atlas's edges. Clear these nodes, unlock nearby Towers, and repeat.
- Clustered Appearance: Finding one Citadel often indicates others are nearby.
Citadel hunting is a late-game activity. Ensure your character is optimally built before undertaking this time-consuming endeavor.
Alternative Acquisition
Crisis Fragments, the reward for Citadel completion, can be purchased via trading websites or the in-game Currency Exchange. However, their rarity often results in a high price tag. Weigh the cost against the time investment required for hunting them yourself.
