One of the problems I've just run into (and this was my first full day of switching my campaign to PRPG) is the possibly of using unlimited detect magics in combination with the Appraise skill.
My quick solution to keep my players from casting detect magic, rolling appraise, rinse and repeat was to make them take 20 with the appraise skill with a casting of detect magic, but I'm not sure that's the best solution.
Anyone else have this problem yet?
