Discover the locations of all 11 Challenge Cubes in One Piece Odyssey, including bosses like Akainu, Aokiji, and Smoker. Learn about their rewards and recommended levels.
Alright, let's dive into the Challenge Cubes in One Piece Odyssey! These are super important for getting powerful accessories and even a trophy/achievement. There are 11 in total, and you can tackle most of them in any order you like. However, you'll need to beat the Smoker boss in the Desert Near Alubarna first to unlock the rest.
Here's a breakdown of where to find each of these tough opponents:
| Boss | Location | Comments |
| Akainu | Marineford: Ox Plaza Bell | South of Marineford in the rubble area |
| Aokiji | Marineford: Ox Plaza Bell | South of Marineford in the rubble area. |
| Bon Clay | Alubarna City | North of the city near the Mausoleum. |
| Burgess | Dressrosa City: Coliseum Path | Northwest corner of the city area. |
| Crocodile | Alubarna Royal Mausoleum | Near the Glyph area on the fourth basement floor. |
| Doflamingo | New Royal Plateau -3rd Level: Sunflowers | Fast travel to the N.R.P Sunflower Field, and the cube is near the castle grounds. |
| Hakuba | New Royal Plateau - 2nd Level: | Fast travel to the N.R.P 2F Entrance and the cube is directly ahead of the fast travel sign on a building. |
| Kaku | Tower of Law | Follow the staircases all the way down until you get to the Underground Passage, where you thought him in the main story. |
| Kizaru | Marineford: Ox Plaza Bell | South of Marineford in the rubble area |
| Rob Lucci | Water Seven City Sewers | Head toward Franky’s hideout through the Sewers. |
| Smoker | !Desert Near Alubarna: Alubarna Ravine | Near the border that leads to Alubarna. |
Once you manage to beat any of these Challenge Cubes, you unlock the ability to fight them again. Be warned, though – these rematches are significantly tougher! The bosses get much stronger, with higher defense that can make your attacks do only 1 damage if you're around level 50. It's highly recommended to be around level 70 for these fights. If you're struggling with leveling up, definitely check out our experience farming guide.
Defeating each challenge cube twice is what earns you the trophy and achievement for this feature, so keep at it!
Beyond the achievement, there are some sweet rewards for taking on these challenges. Completing the initial introduction quest gives you the Odyssey Power accessory, which boosts HP by 3000. Each boss also drops a unique, powerful accessory that's great for specific situations – think poison resistance or other niche buffs. These are fantastic for fine-tuning your character builds to handle different encounters. So, make sure you're leveling up, finding these cubes, and experimenting with accessory fusions to create the best builds for your crew!
