I went to the discord and put some of the mods from there into the folder but I don't think that it's working since I don't see any of the things in the game
It might be a version issue. Try again with the public version that comes out next week.
Also, in the current public version (2.7) mods don't work on Linux. That will also be fixed then.
Also some of my items when I equip them they turn into something else and I have no idea why
That's called cursed equipment.
