Not knowing a person's levels, skills, spells or whatever else makes combat with them more risky. It's much easier to appraise risk if you have all the information.

Darke is meant to be a game filled with risk and danger (at least, that is how most people seem to see it). Therefore, taking away some amount of risk is a bad thing. You should come up with better reasons for doing it than, "I wanna know." It's fine to wanna know, but it's unlikely anyone will agree with you on such personal and objectively flimsy rationale.

Octavian, incidentally, was level 81/72. I feel comfortable revealing that now.
