OP, what slot can i start on Chaos difficulty mode ? I dont want any spoiler so i dont read the each description of your starter saves
If you want to save time for the difficulty trophies - you can earn the universal master & master of chaos trophies by simply changing the difficulty before the final boss. You can of course play on a new game, any save on this thread will work - but it’s quicker to use an end game save. Kill the final boss, save the data. Load the cleared data. Change the difficulty settings in the menu & repeat the boss. The game doesn’t lock the trophies if you change your settings. Assuming the devs haven’t patched it.
