Soo you are in Grand fantasia. Further, you have left Siwa Island and now you are wondering how do I level fast?
If your looking for the QUICKEST way to level the answer is going to be rep Quests, this means killing the same creatures over and over again.
Most likely you will be leaving Siwa at about lvl 10. Go ahead and choose whichever town you want to be near. Buy the quill publishing books from the merchants for some extra cash(since you will be killing the same things normal qsts tell you too). Do all the normal quests until you hit lvl 18..its fairly fast to lvl at this low stage. Boss or party quests need a full party, dont attempt to do them alone, and skip the pc qsts for now.
at lvl 18, go to ancient forest and start collecting honey bear meat and fat. By lvl 22, u will have tons of these, turn them in and it will lvl you up to 23 right away, possibly up to 24. this quest gives off wolf mounts too, so that is a plus.
If by chance you are sick of killing bears, u can also opt for fat bat guano rep at red ridge.
At lvl 24, go to southern island and farm crab meat. Just keep doing this rep quest till 30. this won't take too long.
at lvl 31, either stay at southern island collecting pirate bandanas or start doing merchant rep right away at Angoya Island. The merchant rep qst is a good choice, since, you can combo it with the sunbird meat rep. Lots of things to do here in Angoya, so you can stay here till lvl 37ish
At lvl 37, go to bone reef peninsula and farm sabrecat tusk claws till 38
At lvl 38, do pirate rep. collect all the green gun powde rkits that they drop. The rep quests for these will be unlocked at lvl 40. You can do pirate rep/greenpowder till lvl 42.
At lvl 42, things will start to get slow, best thing i found was doing Kaslow guild rep, Jale guild rep and head at scorching wind dessert. While doing the guild reps, the mobs that u kill also drop rep items, collect stomach bag of water, and essence of the dead. All of these rep qsts are done by just killing 4 different mobs close to each other. Do this untill 45/46
At lvl 45/46, head to land of sighs and do dragon rep till 48. u can also go for kaslow and jale rep combination with bandit badge rep....but that involves ALOT of running.
At lvl 48, head to misty wetlands and do passenger rep. grab the ilya guild rep while doing this. jelly rabbit crystals drop here too, so u got 3 rep quests.
At lvl 50, head to lost highlands and do kaslow + jale guild rep while collecting highland deer skin.
At lvl 51-55 Yak rep in Lost Highlands while collecting Spellcaster's Yak Horns (rep item quest activates at lvl 52, 12 horns per turn in)
At lvl 55 your going to do spider rep in Blakatoa Range
At lvl 60 ACV dungeon or camp rep, acv has some good blues though so you might want to run it for the money/blues/skills/xp plus you might even get a bear mount :-p
At lvl 61 you move to prism island, your going to want to get both of the camp rep qsts to kill lizards, prairie elks (deer), and wild armored beasts. One quests will be a rep quest for just the lizards, the other with be a map quest for all four mobs
At lvl 63 you have two options, either begin jelly rep in Prism or begin collecting necklaces which you can now turn in and continue to until you hit lvl 66.
SOME classes are able to farm fast exp buy killing just the goblins at the entrance of SMF. Classes which can at this lvl are Clerics, Wizards, Demonologists, Sages.
At lvl 65 congrats you get to class change again and will jump to 66 after doing a small quest.
At lvl 66 you will head on towards Knight Valley. You will want to kill soldiers for the soldier rep along with the guild rep, if you are in a good party some one else can work on the wolves map quest.
At lvl 68 you should now find yourself in Eternal Mountains. Farm the lion lizards rep quest and the bee kill rep quest.
At lvl 70…well for now your at the current lvl cap…go run Phoenix Tower and make money and get the great blue sets which come from there.
