How is it not possible for you to OHKO Ice Bears? That's really the best place to go, but if you can't do that.. I'm afraid there's really not that many choices for your level.
There are Abyss quests, also. 12m experience per quest. But if you plan to hunt the items, be prepared to waste many, many hours.
