Vanishing Act

Thief. Make a Stealth check even while observed if there is any crowd, smoke, shadow, cover, doorway, furniture, moving creature, or distraction within 30 ft. On success, observers lose direct track of you until you attack, speak loudly, or enter open view.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
