well, here is a tips to train your thief job
ask a friend to go as trader and make a 5 star camel, then go near south gate, there is a spoton the east wall of south gate, in front of the trader shop where the safe zone didn't work, you can summon a camel as a theif.
Now the trader drop the stuck on the pvp zone and thief pick it up. and walk a few step to the trader shop, you wont be able to go there, the safe zone wont let you go, now use your den return scroll.
why should you go there and not outside? well it's the nearest spot, and when the 5 npc thief will spawn, some of them will spawn in safe zone and disapear, so it's easier with less thief
you could bring an hunter freind and stay in the pvp zone so he can kill the thief and lvl his job at the same time
