 * Location: Gate of the Dead (C-7) - Place a weight on the 4th pedestal from the left. Then, either stand in place (don't get knocked back!) or move all the way left or right before the lasers come to kill you. Flip the map after the jingle plays and then open the chest in front of you.
 * Might be permanently missable, too? Haven't tested thoroughly.
 * Description: Lumisa can perform combo attacks by rapidly pressing the Attack button, greatly increasing the effectiveness of certain weapons.
