There are one or more treasures on each map that aren't visible till you stop on an adjacent square, so finding them can be tricky. The treasures seemed random though. One time I found a treasure, then died, and when I got it again it was a different treasure (but on the same spot). It was usually money, though sometimes it was armor or a weapon. But I did get a couple of nice skills that way.
The skill system is pretty flexible. By the end of the game I was tweaking each character's loadout before battle if not changing them outright. You should definitely give the game a go if you can find the time.
