History[]
- Arcane Ultimatum was first introduced in the Trial mission The Jordas Verdict, which was retired in Update 22.14 (2018-03-01).
- The Operation: Scarlet Spear event sold Arcane Ultimatum from Little Duck for 2,000
Scarlet Credits. - The Operation: Orphix Venom event sold Arcane Ultimatum from Father for 400 Phasic Cells.
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
- Parazon Mercy kills will activate the effect.
- Duration can be refreshed.

Patch History[]
Update 35.5 (2024-03-27)
- Fixed context action Finishers not triggering “On Finisher Kill” Arcanes (Arcane Ultimatum).
Update 34.0 (2023-10-18)
- Fixed several cases where the game was not recognizing a Ground Finisher for the activation of Mods and Arcanes. The intent is that Ground Finishers, Stealth Finishers and Parazon Finishers should be equivalent unless explicitly stated otherwise:
- Arcane Ultimatum will now activate from Ground Finishers
Hotfix 31.7.2 (2022-08-17)
- Fixed Arcane Ultimatum not proccing off Ash's Bladestorm.
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.
