From Guild Wars 2 Wiki
- Venomous Aura — When you use a venom skill, you apply the effects to all nearby allies as well. Venom recharges are reduced.
- Leeching Venoms — Gain might when activating a venom. Siphon life from your foe when triggering a venom. This can only occur once per strike.
- The venom is still used if an attack is blocked, evaded, obstructed, negated by Blind, or if the target has Invulnerability or Defiance.
