I'm probably quitting this game if I don't see a solution because I'm locked inside that feral border dungeon and apparently no way out.

Actually it's the part right after you defeat the feral king. Then I took the warp back to the Ethereal Est and then descended the Feral border dungeon (or something like that). On the 10th last floor, there's nothing there.

I have to go Navia and the only way out of the Est is through a 10 level dungeon but there's no way out there.

Hi,

 

How do you kill a metal beast inside Bart Prison? Everything I tried missed.
