First for the job level 1-10, firebolt level 4, fireball level 5 in Ragnarok, we recomend that you level at poporings/porings/mandragora until you get firebolt lvl 4. You can now solo poporings or mandragora or head to floras at mt.mjolnir once you have this skill. Keep your distance from the flora's as they have a ranged attack that will hurt your low hp. firebolt the floras until they die, you should be gaining very decent exp here.

Then for the job level 10-21 sight 1, firewall 10, as you gain the skill fire wall it opens a whole lot of new ares to train as it acts like a barrier protecting you from enemy harm. once obtaining fw level 5 head to argos map, ( 2 north of prontera castles) use fw to protect yourself from the agriopes and kill them using your level 4 firebolt. Beware of mantis as they deal a decent amount of damage so pack some fly wings and pots for this journey.Hodes are also a nice place to level if you are sick of argos giving decent exp just fw and fb them but keep sight up as they can hide.

Last for the Job lvl 21-27 firebolt level 10, we recomend that you increase your firebolt to its maximum level of level Ro zeny 10 at this stage, mainly because this will be your main offencive skill and can deal out alot of damage. And you can either stay at argos/Hode or you can migrate 1 map north of argos and play around with some agriopes at this stage. Agriopes give extremely good exp at this level and if you have learnt how to play your mage decently then you can gain up to 2-3 levels an hour.
