  • The maximum speed reduction is capped at 75%.
  • Reductions to movement and attack speed, and the longer staggers can be further increased by Cold b 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.


  • It was obtainable during the Artifact Defense Event, and is now in the alerts drop table.
  • Hotfix 11.5.6 lowered speed reduction from 5% to 3% per rank.
  • Update 13.8 changed the Aura to a radial effect focused on the user, as opposed to a map-wide effect.
