Notes
- The additional armor is unaffected by mods. For example, a
Chroma with a max rank Steel Fiber, and an active rank-5 Arcane Ultimatum will have an armor rating of:
- Armor = Base Armor × (1 + Armor Mod) + Arcane Ultimatum
- Armor = 350 × (1 + 1.1) + 1200
- Armor = 1935
- 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.
Trivia
- This arcane was originally dropped in The Jordas Verdict. Following Update 22.14 (2018-03-01), all Trial missions were retired from the game and the arcane drops in turn were moved to the Eidolons instead.
Patch History
Update 22.12 (2018-02-09)
- Armor applied is now an absolute amount (instead of relative) with a base value of 150 with a duration of 5 seconds at base rank.
Update 17.9.1 (2015-10-29)
- Introduced with The Jordas Verdict.
