— In-game description [?]


  • Poison is applied each second for the duration of the area of effect.
  • Daze Interval is unique per Choking Gas AoE.
  • Triggers Signet of Malice once for the initial damage and once per condition pulse for each target affected.This means if the maximum number of targets are hit with both the initial hit and subsequent 4 tricks of poison, a maximum of 25 triggers for a single field is possible.
  • Great synergy with Pressure Striking, Impacting Disruption and Superior Sigil of Draining.
