You might also have to complete the main story but I'm not sure.Showing only comment. Leave a comment. Can confirm you can unlock this before finishing the main story. I'd advise against it until finishing the story as I struggled to beat the bosses even at the recommended level.Posted by JIManji12 on 16 Dec 22 at 06:12 Leave a comment
