Some Warframes feel like they only start performing properly when abilities are being used constantly instead of sitting on cooldowns or passive uptime.
Arcane Impetus fits into that kind of gameplay, where repeatedly applying different ability based status effects slowly turns into stronger casting power and better energy control over time.
It rewards active ability rotations rather than occasional casting, so the more you stay engaged and trigger effects, the more value you get out of it during combat.
How To Get Arcane Impetus?
Arcane Impetus can be obtained from a mix of Höllvania related content, including mission caches, special encounter drops, and faction based rewards tied to the 1999 update systems.
It can also be purchased directly from Eleanor of the Hex once you reach the required standing rank, which gives a more reliable way to obtain it without relying purely on RNG.
Because it exists across several reward pools, most players will naturally accumulate it while playing different activities rather than farming a single fixed source repeatedly.
Arcane Impetus Effects
Arcane Impetus grants stacking Ability Strength and Ability Efficiency whenever you apply unique status effects through abilities, with each new distinct status helping build and refresh the buff during combat.
At max rank, the bonuses become noticeably strong when maintained, improving Ability Strength for higher damage, stronger scaling effects, and more effective ability outcomes in general.
The Ability Efficiency portion reduces energy costs, making sustained casting smoother and helping frames that rely heavily on frequent ability usage stay active for longer periods without running dry.
It performs best on Warframes that naturally spread multiple elemental or ability driven status effects, since consistent application is what keeps the stacks stable and meaningful.
Over time, it turns active casting into both a power increase and a resource management tool, rewarding players who stay engaged and keep cycling abilities instead of playing passively.

Verdict
Arcane Impetus is most valuable on builds that rely heavily on ability usage and can consistently apply different status effects as part of their normal rotation.
It does very little in passive or low interaction setups, but becomes increasingly effective when your gameplay revolves around constant casting and effect layering.
When used properly, it provides a steady balance of Ability Strength and Efficiency, turning active ability play into stronger output and smoother energy sustain in longer fights.
