just jump into some catas and get to MQ. Sell your guild points to a guild that buys them. Do a few climbs and get enough FG to start upgrading your gear. Cant really guarantee you that you will find really good items. Ive done 130+ climbs and my best item ive found only was worth about 1k. On the other hand you could make 1 climb and find a 270+ EE item and become rich. Its a game about luck rather if you find something or not.
