Get as many quests as possible for one location and do the dungeon at normal mode(solo) or party(master/abyss). Get the guild bounty quests too. I took 1 day to reach lv 10 after my FTG ran out in CDN. From lv 30~37, its 30% per day when i do 3 abyss runs solo+quests.
Dragon nest FTW, Nexon can eat my crap ><
