There's always the Invading the Halls of Mielech quests. Go to Miel A and kill the temple guards. Return 2 of their crests to Kisthik (an Iksar that sits just a bit north of the Miel A entrance in Stinger's Bog)for 4000 exp. Or kill the clerics and guards just beyond the tomb and return 1 ankh and 1 girdle for 6,000 exp. All these creatures are perfect hunting for a person in their 20s and the zone is great exp if you have a group.
