The game needed 5 difficulty settings
Story mode (for your grandma and game critics)
Advanced (you have some experience, but not with D&D, nor finished the game. No buffs, but no real maluses, either).
Challenge (some survival restrictions apply. Without good planning, you may have to reload. Enemy rolls and AC are buffed. Exp is mildly decreased). = current improved Tactician
Tactician (for people who've finished the game and use strong builds. If you can dish out 250 damage/turn with one character, congrats. This is the bare minimum. Later bosses now have 2k hp+. Exp is decreased. Food starts to rot over time. Enemies have 2-3x the health, depending on act).
Bloodmarsh equivalent (for people who literally hate themselves. Exp is decreased considerably. Food rots much faster. Various little nightmare tweaks)
