Notes[]

  • The additional armor is unaffected by mods. For example, a ChromaIcon272.png Chroma with a max rank Mod TT 20px.png Steel Fiber, and an active rank-5 ArcaneUltimatum.png Arcane Ultimatum will have an armor rating of:
Armor = Base Armor × (1 + Armor Mod) + Arcane Ultimatum
Armor = 350 × (1 + 1.1) + 1200
Armor = 1935
  • Mercy kills will activate the effect.
  • 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 31.6 (2022-06-09)

ARCANE STAT CHANGES PER RANK

We’ve adjusted the values of older Arcanes with the goal of making lower rank Arcanes more viable, and more desirable while collecting as a result. In short, there are three stats that each Arcane tends to have (speaking generally) -- for example, a percentage chance, a stat buff, and the duration of the buff.

Certain Arcanes increase all of these stats per rank (making them scale exponentially), but we are changing it so that only one stat is affected by rank (making it scale linearly). The other stats will now be at the max-rank value regardless of the Arcane Rank, thereby buffing lower-rank Arcanes as a result.

Arcane Ultimatum

On Finisher Kill: 100% (was 25%) chance for +200/1200 Armor for 45s (was 8s)

  • Now that the chance is guaranteed, the new description is “On Finisher Kill: +200/1200 Armor for 45s”

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.
