Onnet Forest.
Items Obtained: Rat Morph
From Graal City, go northeast to Onnet Town. The Onnet Forest is the farthest north. It is even a landmark marked on the map. Talk to Ryan and he explains that the forest is cursed and it is easy to get lost.
Once inside the forest, you will see three paths: left, middle, and right. And the maze begins. The second NPC inside the forest also warns you not to get lost. There are four levels, or rooms, in the forest before you find the witch. The 1st level has the NPC at the entrance. So if you see the NPC, you know you are in the first level. However, the 2nd, 3rd, and 4th levels are all identical without the NPC. This is why it is easy to get lost.

The trick is only one of the three paths leads to the next level, or room. The other two incorrect paths will push you back to the previous level. Just use a little logic and you can get halfway through easily. In the 1st level, continue testing paths until the zombie NPC disappears. You know you took the correct path to room 2 when the zombie NPC disappears, so remember this path! While testing the paths in the 2nd level, if you see the zombie NPC again, that means you were pushed back to room 1. So take the correct path to room 2 and keep trying until the zombie NPC does not reappear. That means you made it to the 3rd level, so you should have two paths memorized now. The back half of the maze is a little more difficult since you don't have the NPC to reference. I suggest using any AFK players as a reference so you know what room you are in.
