Diverse weaponry of gigantic proportions decorate the walls of the Arena. The overall design of this area resembles the Colosseum in Rome. The room where the Gladiator is encountered looks very similar to the room where Richter is first met at the Colosseum in Symphony of the Night.
The area has two elevators: the first one is completely destroyed but the other is in working condition and leads to three corridors that hold powerful items.
The boss of the Arena appears at the bottom-left corner of the map. While at first it may appear to be the Giant Bat, it is quickly killed in a cutscene by the true boss, Balore. Soma will still obtain the Giant Bat's soul after the battle, though, which endows him the ability to transform into a bat.
On the right-hand side of the elevator leading to Balore there are a few long corridors, each one containing a challenge to complete. At the end of each corridor is a relatively powerful weapon or item, these include the Balmung and the Rare Ring.
- The Arena has a particular room that deviates from the rest of the level's design. A bathtub (complete with a rubber duck) can be found inside. It is inhabited by a Lilith and a Succubus.
- The room with the two Red Minotaurs will allow the player to level up quickly, as each will grant 1,000 EXP points per kill. They can be killed with a single swipe of the Killer Mantle's soul, Astral Veil, and each one is positioned considerably near the edge of the room, so one can keep entering to kill as many as necessary. If a player has also acquired the Black Panther's soul, the Sherman Ring and the Erinys's soul, they will be able to level up much faster (around level 60-70).
