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

The additional armor is unaffected by mods. For example, a Chroma with a max rank Steel Fiber, and an active rank-3 Arcane Ultimatum will have an armor rating of:
- Armor = Base Armor × (1 + Armor Mod) + Arcane Ultimatum
  - $Armor = 350 \times (1 + 1.1) + 800$
    $Armor = 1535$
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.
