Or if u cant afort an SOS you can go into Kagirina River ( guans name ) with a sup pill + pet+char L kill some mini bosses and some big bosses on a x5 exp day ( usualy in weekends ) it should work pretty fast. In SOS if you dont have good gear or good build + a wasp 100% you can die pretty easy.. if i remember right ( havent played for to long to remember good )
