All I can think of is keep looking for XP: presumably you've done the crocodiles; the teleportation escape; fought in the arena under the kitchen; the acid frogs in the elf cave; the oranges quest; Withermoore's soul jar? You can actually do the latter without getting caught up in any altercations. There's also the cave under the fort that's there to be explored: I'd suggest Petpal, though, but the ensuing fight if you don't have it should give some XP.
