Skeletons and Ghosts
Skeleton
Monster: Skeleton
Difficulty: Medium
Location: Middle Mountain Mine and Forest Mine
The bones of miners passed, or other unfortunate travelers. No one knows where they come from, but they're all over the deeper parts of the mines.
Skeletons tend to be very aggressive, and will hunt down miners. Proceed with caution if you see one.
Skeletons drop many interesting items, so it may be worth your while to fight them when you find them.
Ghost
Monster: Ghost
Difficulty: Hard
Location: Middle Mountain Mine, Forest Mine
These ghosts are the remains of long forgotten souls. They can float through the walls of the mine, so watch out! They will hover around their gravestone, and will only bother you if you get too close. If you do get close, they may charge at you though!
They've been known to write ethereal messages from time to time.
Ghosts are especially deadly, because they will return after you've killed them! There may be a way to release the ghosts forever, but you'll have to keep searching to discover this secret.
