Glass Lurks in Water (3.5e Maneuver)

You practice the art of concealment to its utmost.

Until the beginning of the turn after your next turn, you cannot be detected in any way. Your actions are not revealed to other characters independent of what they are. Thus, you could shoot several people and duck behind a column, but the people wouldn't even realize they'd been shot or killed until two turns later.

You cannot use this maneuver again until one round after it ends.
