At a random depth in one gate of the arcade there will appear an entrance much like a danger room. However it will instead lead to an elevator. The elevator takes the player to Krogmo's Showdown, a three room arena with no arsenals in between. At the start, the player must input materials and rarities. If the player succeeds in beating the arena, all of his inputted mats and rarities will be upgraded one star level. However, each arena will be as dangerous as a danger room and each room will be a different monster type. Perhaps a mini boss too.
