Thank you for playing craspedia!
>Played with thief, fighter, knight
That's impressive, I don't think ive ever beaten the game without a cleric
>Adjusting skills and passives in a dungeon
Yeah that'll be the main bulk of the experience, different from darkest dungeon. You will be switching through equipment very often to handle specific encounters in high level gameplay. A hotkey to save and quickly swap between party configurations is planned.
>Level up mechanic
It is there to encourage exploration and the hard fights with tight MP economy are supposed to push you into using dice and shifting to skip through floors and slip by difficult situations! Likewise no battle rewards also were meant to discourage you from fighting blindly, instead looking for other more rewarding paths to take. But battle rewards are planned to be implemented, they just aren't going to be as greater as exploration rewards
