Xesht, We That Are One Boss Guide

Pinnacle Boss Recommended Level 90

Phase Breakdown

  1. Phase 1: Phase 1 — Full Kit
    TriggerFight start
    MechanicXesht cycles through most of his moveset early: a channeled Sonic Wave (physical projectile), a more dangerous Triple Blast (fired three times), a fire meteor, a lightning shockwave, cold projectiles that can Freeze, and a burrow-chase-clap attack. He also periodically summons the other Breach Lords, Tul (freezing icicles) and Esh (expanding lightning), one at a time.
    CounterStay close and circle behind him, most of his attacks have long aim/turn animations that a close, mobile position punishes hard. Dodge perpendicular to projectiles rather than straight back. Run wide circles around the arena edge if he burrows and starts chasing.
  2. Phase 2: Phase 2 — Arm Slams
    TriggerAround 50-60% health
    MechanicMultiple portal-arms (Breach Hands) rise from the ground and slam down in sequence after a delay, dealing heavy damage, widely called the single most dangerous attack in the fight.
    CounterOutrange the slam if you can, or use a single well-timed dodge roll per arm, don't spam dodge rolls, since you'll need several in a row and rolling too early leaves you exposed for the next one. Ignore the boss entirely during this sequence and focus purely on the arms.
  3. Phase 3: Phase 3 — Combo Summon
    TriggerBelow roughly 60% health
    MechanicXesht chains Tul's ice cones and Esh's expanding lightning simultaneously instead of one at a time, flooding the floor with overlapping hazards.
    CounterThis is where undergeared builds die, it's primarily a speed check. You need enough sustained damage to burn through this phase before the stacking hazards overwhelm your positioning options.

Full Fight Guide

Xesht, We That Are One is the pinnacle boss of the Breach mechanic, fought in the Twisted Domain. Getting there requires collecting 300 Breach Splinters, which combine into a Breachstone, place it into the Realmgate (always located next to the Ziggurat Refuge on your Atlas) to open the portal. Inside, you fight through waves of Breach monsters to extend a countdown timer before reaching the boss arena itself.

The fight has 4 difficulty levels, unlocked and scaled through the Breach-specific Atlas Passive Tree, higher difficulty means significantly more boss health, but a much better loot table in return.
