Acquisition

• Available for  20x Cred creds from the Nightwave Cred Offerings store on a rotational basis.

Notes

• The maximum speed reduction is capped at 75%.
  • This can be achieved by having all squad members equipping this aura with at least two squad members equipping  Coaction Drift too.
• Reductions to movement and attack speed, and the longer staggers can be further increased by  Cold procs.
• When used in conjunction with  Coaction Drift and a squad of four such set-ups, it is theoretically possible to reach the speed reduction cap. However, after testing, it appears that this does not work as expected and the Infested continue to move at a considerable pace.

Trivia

• It was obtainable during the Artifact Defense Event, and is now in Nightwave Offerings.
• Hotfix 11.5.6 (2014-01-02) lowered speed reduction from 5% to 3% per rank.
• Update 13.8 (2014-06-19) changed the Aura to a radial effect focused on the user, as opposed to a map-wide effect.

Patch History

Update 27.2 (2020-03-05)

Faction Aura Changes

We are rebalancing the faction Auras to not completely bypass our rebalancing effort. More importantly though, with the complete rescale these Auras (mostly Corrosive Projection) will not be as necessary as they were.

Corrosive Projection, Shield Disruption and Infested Impedance new Rank values are:

• Unranked: -3%
• Rank 1: -6%
• Rank 2: -9%
• Rank 3: -12%
• Rank 4: -15%
• Rank 5: -18%

Why: We think being consistent is key. Passively removing 100% of an enemy's defenses is not an interesting choice, and we were completely inconsistent in this regard with Auras (i.e the efficacy of 4x Corrosive Projections vs 4x Shield Disruptions).

Update 25.7 (2019-08-29)

• Increased the range of the Infested Impedance Mod from 8m to 16m.
• Fixed Infested Impedance not affecting some Infested enemy types. As reported here: https://forums.warframe.com/topic/1121929-infested-impedance-aura-doesnt-work/

Update 13.8 (2014-06-19)

• Infested Impedance Aura mod has been changed to be a radial affect around the player instead of the whole map indiscriminately.

Hotfix 11.5.6 (2014-01-02)

• Changed Infested Impedance Aura to reduce speed by only 3%/level to prevent squads of four from stopping all Infested completely (now a maximized team should reduce infested speed by 72%).

Update 9.0 (2013-07-13)

• Became an Aura mod.

Update 8.0 (2013-05-23)

• Introduced as part of the Artifact Defense Event.
