When starting a new game, you may select from Wanderer, Marauder, and Bard modes.
Marauder Mode: This is hard mode. It is unchanged from the classic difficulty.
Wanderer Mode: This is medium mode. Bosses have less health and enemies are generally slower and attack less often. You start with 2 extra hearts. Added damage in the Necro Pits is halved.
Bard Mode: This is easy mode. You get a bunch of free items like before, bosses have even less health, and enemies are even slower and attack much less often. Enemy attack power is halved. There is no added damage on deeper floors of the Necro Pits.
You can't change the difficulty once you start the game.
For those who have save files already, your difficulty will be set automatically when you load the game. Bard Mode will be easy and Marauder Mode will be hard. To try out Wanderer Mode, you'll have to start a new game.
