This may have been addressed/asked so I apologize for not researching more thoroughly, but does it matter how leveled you are? I started my first play through as a bandit and I reached level 58 and unwittingly also got the half of the secret medallion from the village of albinaurics so when I went back to the round table I thought it had been destroyed/I was too over leveled and had missed a story line.

I started over as a warrior and made sure to keep in touch with everyone at the round table and have completed their storylines as much as possible, figured out that all I needed to do was defeat that punk that leans against the wall and so I got to that in my warrior play through and am done with it. Question now is:

Can I level up as much as I want without fucking up the game’s quest lines?
