When starting a new game, you will be able to choose between normal and hard difficulties. The former is recommended for players new to tactical role-playing games, while the latter suits veterans.
Even more challenging than hard difficulty is lunatic. This game mode is expected to feature even more challenging enemy AI, higher enemy level progressions, and more damaging enemy skills and abilities.
Lunatic mode will be available as a free game update, though no official date has been disclosed by Nintendo. We will update this page when new information comes out.
