So you want a simple version of dungeoncrawling. Here is a freeform interpretation.
Choose a type: Brutish or Erudite.

Roll d6 for each column:

| accountant | magical knowledge | paranoia | a translation guide |
| lord | knowledge of nature | recurrent illness | a stack of cash |

| navigator | steady hand | exile | an expert map of the area |
| scholar | detailed memory | greed | a bestiary |
You may have a spell. You can cast it once a day without consequence. Beyond that, see if your control of the power is strong enough to prevent a mishap.
Roll d6 or choose, as you please.

Give hard choices and dilemmas, provide maximal information. Play dungeon denizens as smart as players do.
