Maybe it is hard to level 30-40 in All Points Bulletin for youself, follow us which can make you more easier and faster.

Level(apb gold) 30-35: Move back to Ascaron and go to Valhalla Haven, you can get there by talking to the teleporter at Abandoned mine haven and just follow the chain of teleportation untill you get to Valhalla. The order is: Abandoned mine Haven, Rockery Haven, Andes Forest then Valhalla Haven Go kill Grassland Elks and White Owlies. Use Berserk skill to boost your speed and attack about 3-4 monsters, rest until Berserk cools down and go again till it is really slow. You'd better to look for a healer or an explorer to help you which was a pain. Elks and Owlies are non-aggressive so you can stay there and rest. You must note that if anyone knows a better place please add.

Level 35-40: Find a healer and team with her in the Abandoned mine killing Miner Moles at level 35, and Ninja Moles at level 38. Then you are depended on the healer and congradulations that you have reached the second multiplier on Illusion Slash and this means one hit KOs on Ninja moles. Ditch the Healer to get the extra exp and kill untill level 40 when you can become a crusader.
