  • Capturing the Eidolon Gantulyst grants a 5.29% chance to get an ArcaneUltimatum64x Arcane Ultimatum, killing it will not yield this arcane.


  • The additional armor is unaffected by mods. For example, a ChromaIcon272 Chroma with a max rank Mod TT 20pxSteel Fiber, and an active rank-3 ArcaneUltimatum64x Arcane Ultimatum will have an armor rating of:
    • Armor = Base Armor × (1 + Armor Mod) + Arcane Ultimatum
      • Armor = 350 × (1 + 1.1) + 800
        Armor = 1535
  • This arcane was originally dropped in The Jordas Verdict. Following Update 22.14, all Trial missions were retired from the game and the arcane drops in turn were moved to the Eidolons instead.
  • The effect can be activated by the user's Sunika or Sahasa kubrow performing a finisher attack via their unique precepts.
  • Duration can be refreshed.
