As you would imagine, Normal is the middle of the pack difficulty that most players typically choose. Normal is a solid choice for beginners that don’t want it too easy.
Signficantly challenging combat.
Hard is well.. Generally hard. In this setting it is more important to think critically and make plans of how you will about each encounter.
Exceedingly challenging combat.
Mericless isextremely difficultand provides a real challenge because your foes hit very hard and take less damage. In Tartarus, if you die, you load back up at your last save.
Merciless needs to be chosen from the start and you are stuck once you select this settings. It is important to note that trophies are not gated behind Mericless so it should be chosen by Veteran players who want a real challenge.
