If you are stuck on Level 60 for Fiesta Online , here is just the leveling guide from level 60 to level 89 , it is very simple for you to learn . Hope helpful !

Level 60
Spam Spider. Do a few quests if you want, but save the majority of them. Pvp kq is wonderful exp. Maybe pop into abyss if you want some fiesta gold as well as exp, but mostly this lvl is pretty easy. There's a King / Queen Spiders repeat in CP1 you can do. Personally I would just spam Spider, sell the mats, and get up fiesta gold  to help fund yourself.

Level 61
Again, between Spider KQ, Pvp KQ, and a bit of questing, you should level pretty quickly.

Level 62
Again, still spam spider kq. It gives the most exp for 60-63 than further on and makes fiesta gold more of a difference here. You now have a repeatable quest: Amnesia 2, from the Smith, asking for first 40, then 60 King Mushroom Spores. While this quest takes a while, with a good pt (at least 1 mage preferably, and 1 cleric), you can easily get it done. It gives LOADS of exp, so if you cant go to abyss, and dont wanna do your other quests, do Spores. Either way, I recommend you do the 60 Spores part AT LEAST 3 times.

Level 63
Still do a bit of KQ, but if its taking a while, do some quests. Start with the easy ones that are grouped together. In other words: Pick a map you have quests in, and do only those until you level. Grouping the quests together like this means less walking from map to map, and more exp-making.

Level 64
Save the bats quest (Big Bright Golden Bat Tail Hair). I mean it. Save it. Do the other quests, but keep the dungeon one still. You might have to grind in abyss for part of this lvl (I did for 10%), but it should go pretty smooth again. If you level and still have other quests besides Bat and Dungeon, save them for 67.

Level 65
You now have Dreadful Elf in the Forest 2, asking for 120 Greenkies and 30 Greenky Big to be killed. Spam it. Save all other quests.

Level 66
Same as 65.

Level 67
Do all of your 65, 66, and 67 quests. You should level. If not, spam out KQ for the remaining exp.

Level 68
You now have Hair Remover, calling for you to kill 70 Lizardmen and obtain 20 Muds. Save all other quests.
