Level 21-30: At level(Maplestory powerlevling) 21, Kerning Party Quest is available, and as a Magician, one will be invited readily for the quest. If you get bored of Kenning Accompaniment, you can try the Ariant Coliseum, available in versions with Ariant. You could stay on the green and horny mushies. Or you could go and destroy Jr sentinels in orbis tower by using the off-land sniping spots.
Great money and good exp(Maple Story Mesos) if you start at an early level. In GMS, go hunt the nearby normal cactus's and kill them for 47 EXP. At level 27 go kill green trixters and not take damage because they always move vertically. Level 28-30 go crazy on teddies or flower fishes. You should have a good time inMaplestory if you follow these instructions.
