Enhancing Magic skills up at the rate of offensive magic if you use it on, say, NPCs in besieged. Haste 'em, for instance.
Enter Beseiged, get temp items, max out MP with drinks if available, Chainspell, use Revitalizer, then spam your spell of choice on an NPC. Die/warp, reenter Besieged and do it again.
Same thing works with Healing, though for that you can go cure undead as well.
