Here is the information for level 59-67 in Atlantica. That is the Hanging Gardens of Babylon.

For the first time in a while, you will encounter some easy enemies with one or two exceptions. Almost any enemies here are good for farming with the exception of the Keysha enemies. The Slave mobs is nice. They're relatively weak but still give decent experience and drops.

In this game, most of the enemies here are fairly weak and worth training on. The first miniboss here is the Iron Doll Reaper and it only appears in the entrance area. It attacks like an axe would so that means your entire row could be dead in a few hits so keep that in mind. The second one here is like a giant Lionman. They tend to drop a Secret Material Chest.

Something that lets you pick from either Growth Vials or Mandragora. A lot of people are willing to pay high for Mandragora, but Growth Vials are much more useful to you in the long run. The Prophet quest does not begin until level(atlantica gold) 70, so in order to obtain it you will need to revisit here later. The boss here (Tiamat) is fairly tough as well. You can get Osiris gear or Judgment scrolls before coming back for a serious fight with it. It can attack an entire column and has a powerful area skill as well.

At level(Atlantica powerleveling) 63 you can do the Princess quest. Its fairly simple and very easy compared to the Exorcist one. A group of 2 will do nicely and the enemies have low HP and high damage. The Crazy Minotaurs are a nice place to train and farm. If you plan to get an Inventor, you must do the Princess quest and level her up to 50 first.
