The largest cash of experince in one fight is in the Tower Ruins. Nasty fight that I would not try to tackle less then a party of level 4-6 and have at least one large area holding spell readied. Plus a pile of luck/reloading to have the area holding spell fired off just about firstly. No spell casting until at least half the ranged attackers are taken out or is done quickly in the the begining before the ranged attackers activate.

You will gain one level reguadless fighting here.
