Trial of the Sand Colosseum Location
Located in the desert, access this Colosseum from the Desert: Center access point. Zoom out and look right for an orange diamond-shaped structure. A machine guards the entrance but poses no significant threat. Completing this quest offers various rewards, with the Rank S reward being the Destroyer Outfit (A2).
Gambler's Colosseum Location
Start at the Flooded City: Coast access point. Follow the path to the coast (the same route used to protect the resource ship). At the end, look right for a waterfall. Circle around the building to the left, finding a Resistance member guarding the entrance. Bribe them with 1,000 G to enter and begin the Gambler's Colosseum quest. The Rank S reward is the Revealing Outfit (2B).
Underground Colosseum Location
9S only. Begin at the Forest Zone: Center access point. Follow the forest's left edge until you find machines training near a large waterfall. Pass through the waterfall to access the Colosseum. The Rank S reward is the Young Man's Outfit (9S).
