Mastering Map Device Portals with Secondary Calamity Fragmen

[Matthew]

Secondary Calamity Fragments unlock advanced portal mechanics at Path of Exile 2's Burning Monolith, elevating standard Arbiter encounters into pinnacle Uber fights.

Portal Activation Process

Locate the Burning Monolith on your Atlas after progressing through mid-maps and unlocking towers for visibility—head to the sealed door near the origin point. Slot all three Crisis Fragments together: Primary (Ancient from Iron Citadel's Geonor), Secondary (Faded from Copper Citadel's Jamanra), and Tertiary (Weathered from Stone Citadel's Doryani). This ignites the altar, spawning modified portals that lead to Uber Arbiter of Ash with ramped difficulty—20-30% more enemy damage, chaos pools, illusions, and level 85+ areas packed with 6+ modifiers.

Fragments are single-use per instance but allow unlimited portal retries until death downgrades to base Arbiter. Prep level 90+ builds with capped resists, mobility skills, and ignite/chaos mitigation to survive one-shots and bullet storms.

Secondary Fragment's Unique Role

Among the trio, Secondary specifically amps aggression: It spawns spreading chaos hazards and phantom adds during traversal, testing positioning while boosting rare drops like Prism Diamonds and exclusive uniques. Without it, Primary/Tertiary alone yield weaker base portals missing mythic rewards. Farm T15-16 Citadels juiced to 500%+ waystone quantity for 1-3 Secondaries per Jamanra clear, chaining via Visions of Paradise for 20+ hourly.

Mastery Strategies

Allocate 10+ Atlas points to boss-slay nodes and waste quantity for sustained sets trading at 6+ Divines. Enter overleveled for safety—Arbiter phases include ray bursts, split earth, and orb storms; dodge center during charges. Post-clear, spend Arbiter Tree passives like Ancient Relics (25% rarity) or Witness to History (20% extra uniques) to compound loot. Trade singles early league (1.5-2 Divs each) or hoard for bulk Uber pushes, turning portals into 30D+/hour printers in Abyssal metas.
