In Path of Exile 2, accessing the Burning Monolith door the gateway to the Uber Arbiter of Ash and pinnacle endgame content requires combining three unique Calamity Fragments. These fragments correspond to three Citadel bosses: the Primary Calamity Fragment from the Iron Citadel (Count Geonor), the Secondary Calamity Fragment from the Copper Citadel (Jamanra), and the Tertiary Calamity Fragment from the Stone Citadel (Doryani). Each fragment is a rare drop rewarded from defeating these Uber Citadel bosses at the highest difficulty.
Once all three fragments are collected, players must travel to the Burning Monolith, a special structure revealed by progressing through the Atlas and clearing towers, which increases map visibility. The Monolith initially appears as a sealed fortress locked by a mystic door requiring the trio of Calamity Fragments for entry.
To open the door, players interact with the sealed passageway at the Monolith and insert each of the three Calamity Fragments into their respective sockets. This combination unlocks the portal to the Uber Arbiter of Ash arena, initiating the endgame boss fight. Insertion requires careful interaction players must hover over the door’s slot areas to insert fragments, and sometimes pressing the "Alt" key helps resolve interface issues with fragment placement.
The Burning Monolith itself is accessible only after unlocking and completing quests from defeating the three Uber Citadel bosses, who guard these fragments. The door remains sealed until all three fragments are slotted, symbolizing a key system requiring mastery of the Citadel bosses.
This design ensures players engage with high-level Citadel content to earn access, emphasizing both challenge and progression. Upon unlocking, players can advance to face the Uber Arbiter of Ash, one of the toughest fights, with rewards proportionate to the effort invested in acquiring and combining these powerful Calamity Fragments.
