Ultima Forerunner

General Notes Appears in CN Temenos Basement once all T3 objectives are met. Possesses party-wide aggro mechanics. If any member of a party gets aggro, even with 0 enmity, Ultima Forerunner will not reset until all members of that player's party are defeated. Can do double auto-attack. Uses Dissipation immediately once reaching 70%, 35%, and 10%. Dissipation can be blocked with Asylum. Uses Citadel Buster every 3-5 minutes. Damage can be mitigated by Sentinel's Scherzo, Migawari: Ichi or Earthen Armor. Nuclear Waste spawns six Ultima's Zisurru (fetters) on a designated player in the area. These fetters have a 30' AoE range, attack through all terrain including walls, attack immediately on spawn, deal ~500 damage per hit, and their damage cannot be resisted. Ultima uses this roughly every 3-6% HP. After 89%, Nuclear Waste is used 65 seconds after Citadel Buster. The Fetters despawn about 30-60 seconds before Ultima uses Nuclear Waste again. Gains Energy Screen or Mana Screen under 50%. Only has one at a time. In the event of a wipe, aggroing the Zisurru may cause Ultima to link and aggro as well. Upon defeat, upgrades treasure chests in Apollyon for the following 4-week cycle to gold. Has no effect on treasure chests in the ongoing cycle. As of December 2025, Defense, Damage Taken, and Shield damage reduction do not work correctly against this NM. As a result, Utsusemi and builds that prioritize high HP are recommended. Judicious application of debuffs and Geomancy along with large quantities of direct healing are essential to survival. See the Discussion page for published testimonials. Ultima Forerunner Adversary Type Unclassified Family Biotechnological Weapon Job Class Limbus NM Resistances A: Absorbs · S: Susceptible · R: Resists 100% denotates that a monster takes full damage. Tiers of 50% or less guarantee a spell resist.
