Vermillion Tower is a location in CrossWorlds. It is the current final dungeon of CrossCode. This is technically the same location as the Vermillion Dungeon, but it has been completely reconfigured by Gautham. Since this is the final dungeon, it is fairly linear, with little in the way of exploration content.
Vermillion Tower consists of six small floors connected by an elevator. The ground floor consists of an entrance chamber and an elevator room, while the first and second floors each have two loops of puzzle rooms. The third and fourth floors consist of a single room each, consisting of a boss battle and a final bounce puzzle respectively. The elevator banner initially implies that there will be many more floors, but after the fourth floor the elevator goes all the way to the top.
