[ACT III] Areas for levelling *spoiler*
Besides what was previously mentioned (the alp that regenerates after meditating during the Yaevinn quest), another fine area to level up is in the warehouse during the bank robbery. The 5 fleders (?) regenerate if you exit from the bottom door and come back again, but won't once you finish the quest. That's about 1000 - 1500 exp per entrance! Enjoy! Sorry if this has been mentioned before.
