I think you will have to buy some gear for the very early ilv check around lv8. Unless you befriend someone to make you gear to get past it. Or you could make it yourself. Also if you still have access to your old character you could do new game plus.

Kind of curious as to why you think you can't just continue on and slowly make money from selling things. Like are you so poor you can't teleport from where your old character is? Or do you think that you'd have enough for a medium house. Just curious is all why you feel that you must redo the msq just for the gil as that seems to be the driving force.
