Post-Game Unlockables Guide for The DioField Chronicle
New Game Plus (NG+)
After clearing the main story campaign on any difficulty, New Game Plus (NG+) is unlocked, allowing you to start a new playthrough of the game with all of your acquired weapons, accessories, skills and abilities, Magilumic Orbs, items, and money (Guld) carried over.
Note that enemy level does not scale with your level in NG+. This means that you will be able to clear the main story much quickly than your previous playthrough which is useful for grinding out and leveling units that you did not focus on before.
NG+ also gives you a good opportunity to aim for 100% completion (Platinum) by unlocking trophies and achievements you missed on your first run.
