As it happened to me in pretty much every RPG I played, it turns out that my initial choices of skills weren't exactly ideal. The first character I meet has exactly the same skill at maximum level that I have. The second I meet also has this skill as his highest. This in turn means that I currently have no character that has focused entirely on mechanics, only a bunch of characters at a reasonably high, but not high enough level for the traps I'm encountering right now.
Is there a way to respec skills? I'd prefer an ingame mechanic, but I would consider using a cheat, console command or editor as I just want to switch around skills, not increase the absolute amount.
