The cool cost reducing mechanic shows up on Bartz and Boko to care about birds (which includes chocobos), Travel the Overworld for towns, and Valkyrie Aerial Unit for artifacts

Its ability seems insane with Smoky Lounge // Misty Salon, Unholy Annex // Ritual Chamber, or Experimental Lab // Staff Room and Intruder Alarm, letting you continually open and close doors
