Notes[edit | edit source]

  • The additional armor is unaffected by mods. For example, a ChromaIcon272.pngChroma with a max rank Mod TT 20px.pngSteel Fiber, and an active rank-5 ArcaneUltimatum64x.pngArcane 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[edit | edit source]

  • 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.

  • 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.
