I'm not too familiar with the ZMI thing as I haven't been a member in quite some time. But, some of the fastest exp you can get is get a bunch of rune ess(not pure), a fire tiara, and a bunch of dueling rings. Tele to duel arena, make the short run to the fire alter, craft, tele to castle wars, bank, repeat. I think you even cut a small profit if you are at the level for triple fires(can't remember what levlel it was.)
