Thanks to PSNProfiles, One Piece Odyssey trophies have been revealed. The list (which of course will be identical in the Xbox version) gives an idea of the activities that we will have to carry out in the game and makes us aware that Platinum can take a long time.
There will be no spoilers in this news, so if you want to see the list of trophies in detail, you can go to this page. You can see that the loot series is only explicitly related to completing the story missions, but there will be objectives for side missions, for crafting various recipes, and for opening each closed treasure chest. You can then explore, obtain items, and complete various quests for the One Piece Odyssey platinum.
You also have to go through 300 battles, defeat powerful enemies twice and upgrade all characters to level 70. Of course, the list does not allow us to determine the exact number of hours required to complete this activity, but if we talk about a Japanese RPG, then the hour counter can go off scale.
As a reminder, One Piece Odyssey will be available from January 13, 2023 on PC, PlayStation 4, PS5 and Xbox Series X | S.
