As an adept player I'm trying to figure out how my character is OP'd compared to the rest of the team. The tech priest, guardsman, and assassin blow my adept out of the water in combat. When it comes to social skills, yea forget it not my character's cup of tea and she doesn't care. Knowledge, maybe depends on what you want to know. My character has 1 CL, 6 SL's, and 6 FL's with an Int of 52 with one advance left to take. If you want information pertaining to cults and occult practices ok I'm the person to go to. If you want legal advice or medical knowledge umm yea the hospital is that way and the law offices are over that away somewhere have fun. So this problem about a Sage having better SL (Judgement) knowledge, yea ok I'll believe it if the character is playing a lawyer type of character. As to my character even as a Sage not likely. My character has no care to pick up that lore, she has more important things to do, hunt down books that shouldn't be out there, hunting down cults, and the occasional demon. Maybe I'm playing the class wrong I don't know.
As to Illithidelderbrain's scenerio, my adept would've helped the tech priest to shut down the servitors. We've done it before. Then help the team take down mr big and ugly. After that was done, I'd have helped the tech priest reprogram the servitors to protect us. Then used the whole team to help do the searching, with my adept telling the others where to look, while the servitors were guarding us.
Just my thoughts on the matter. I don't see where this "adepts know everything" concept comes from. I compare adepts with current day people with PhD's. There are different fields to study for a PhD. If using todays fields, an adept with a PhD is physics is definately the person to go to for information pertaining to physics, but a criminal law arbitrator will have way more knowledge in law that the physics adept. I see adepts as equal parts Librarian and either Indiana Jones (male) or Laura Croft (female). Shaken not stirred.
The example I provided could be argued as valid though (hence the point to rules lawyering. And, you did open the door to the skill check example I gave). I also have a problem with this type of scenario:
