Unobservable Stealth

Parent page Stealth

In some cases, it can be impossible for a creature to fully observe you. Typically this happens if you're invisible, the observer is blinded, or you're in darkness and the creature can't see in darkness. In such cases, any critical failure you roll on a check to Sneak is a failure instead. You also continue to be undetected if you lose cover or greater cover against or are no longer concealed from such a creature.
