It's the same way as for chinese characters. You get your 4th degree gear from the NPCs of the second town (Samarkand in this case) and monsters of an appropriate level. The only problem with this is, that the monsters around Samarkand are tougher and more annoying (see my sig

) than earth ghosts and that the ways to your twenty'ish hunting grounds are longer, so you might not want to relocate to the second town when you should item wise.
I haven't been to Samarkand in iSRO so far to check the marketplace, but a way around the teleporter fee could be to put a character in that town, let him buy the gear for your main character and transfer it through your stash.
