Well, I am playing to get to level fifteen as I answer! I would say, its a lot of enemys. But, the method I use, pass until you have four pips, heal, pass, heal, pass, heal, pass, attack with your strongest spell.
first you have to become a level 12 mage, then become a level 5 or higher wizard.
To become a true wizard, you have to reach a certain amount of studs in each level.
you need to go to obsidias layer, after you become a level 10 wizard
To become a legendary, you have to be level 60-69.
Wizards become non-aggressive (won't attack you automatically) when you achieve more than double their level. For instance, a Level 7 Dark Wizard will not attack you when you reach Level 15. A Level 20 Dark Wizard will not attack you once you reach Level 41. Note: normal Wizards (such as at the Wizard's Tower) are not aggressive. They will never attack without provocation.
First you must become a level 10 mage (Warlic's shop--Class Quests--Mage Quests), then you go toWarlic's shop--Class Quests--Wizard Quests. You can go up to level 5 wizard and unlock 4 skills if you are not a guardian.
The current highest level of wizard 101 to get on a single wizard is 60 and the last world of the Spiral is Celestia.
You don't have to be a certain level you just have to beat wizard city
The fastest and easiest way to level up is to have someone leech you. This is the only good way to level up fast at high levels. You have to be in a party with someone level 120 or up in the final job and just stand near them while they kill enemies and you get party experience. The enemies have to be close to your level. Wizard jobs are best to leech because they have attacks that can hit all enemies on screen. You can also buy a 2x exp card or use rep to temporarily give you 2x exp.
at level 38
You have to be level 15.
48 after you get scarecrow.
