Fastest way to lvl up for a new wizard

Wizards find it easier to gain EXP when compared to most other classes.

If you're a person who hates doing normal quests, try grinding turtles outside Etherblade city. Water monsters give 1.5 times the EXP given by land monsters.

If you have gold do not hesitate to buy Hyper EXP Stones, they are worth the cost. Buy 5 of them to get 12 times the EXP. With Hypers and the extra EXP from the water monsters, you will effectively have 18 times the normal EXP.

If you're still feeling greedy, wait for a x2 EXP event. NOTE: they usually come on the weekends. Doing so will get you 14 times the normal EXP, or effectively 21 times the EXP with the water monsters.

OH! And by the way, don't forget to level up Pyrogram, it will help you kill from a far distance.

With this setup you can get around 1k EXP per kill.
