I believe that leveling would only start to get tricky when you are trying to reach level 175. My usual go to maps would be:
Low Level Maps
- Moscovia Dungeon 1 (to reach Base Level 99 Job Level 70 Trans Job)
- Use Yggdrasil Leaf on Anubis (Resurrection) in Sphinx (Instant Level Up) (Just up to 100+) (Tanker might be needed)
- Ice Dungeon Level 3
High Level Maps (up to Level 175)
- Thanatos Dungeon 8 (not recommended when you don’t have a lot of equipments)
- Thor Volcano Level 3
My friend, whom I shall call Mr.Carrots here suggested the following maps:
Novice to Second Job
- Geffen Field 7 and Einbroch Field 7
Reborn
- Geffen Field 7 and Einbroch Field 7
- Ice Dungeon Level 3 (Trans and 3rd Job Low Level)
3rd Job Level Level (120 or 130) until you reach level 175
- Thor Volcano Level 3 (wear Armor with Pasana Card)
Advice and Notes from the Author:
- Buy Cure Free from Pots and Stuffs NPC as your "temporary" Healing Pots.
- In my case, Genetic is the only character that I try to level straight to level 175. I level up the other two, Ranger and Warlock, while I farm.
- Try to wear some equipments for easier leveling. Read the MOA NPC Equipment Section.
