— In-game description

Rigorous Certainty is an effect is obtained from the Mistlock Singularity in Fractals of the Mists.


  • When triggered by lethal damage, the affected player also receives a brief moment of invulnerability.
  • This effect ignores any effect that reduces healing like Poisoned.png Poisoned, Agony.png Agony and Challenge Motes. [verification requested]
  • Rigorous Certainty has a lower priority than all other effects that prevent downed state from Traits, Skills and Runes. So Rigorous Certainty will only be consumed if no other option is available.
  • Assuming the player has activated Infinite Mist Omnipotion or the equivalent and trained the Mistlock Singularities mastery, the 5 AR granted by Rigorous Certainty also grants 7 additional toughness, vitality, and concentration (equivalent to 0.46% boon duration).
