Pay to GM he lvl you up to 94! Money is everything here.

1. If your weapon is B grade, fight YELLOW and ORANGE named mobs
2. Earn exp from Map2 (Scyna Island / Island of Pain) mobs to Level 40
3. Go to Pirate Town in Almighty Land, check out other players'stalls
4. You open stall too, sell BRONZE KEYS and FEHU at market price
If you don't have friends, create 2nd and 3rd charaters (Warrior / Attacker is good), and farm at map 1 & 2 again. Sell key and fehu to other players for gold from your stall, until you have enough (like 400,000,000) gold. Then buy an "S weapon" from other players. With this S weapon, you can truly start farming beyond level 65

Problem is , did you upgrade your class or not ?
