A skeleton was one of the most common familiar creatures used by wizards. However, wizards preferred to use necromancy spells to stuff certain soul inside an existing skeleton to make a Dead Man's Skeleton, in which case the soul could interact with the physical world using the skeleton as a host. Flora's "Little Red" was essentially a Dead Man's Skeleton. But that one was special, considering how it came from the Nightmare Realm.

For a Dead Man's Skeleton, the soul was its true body, while the skeleton was its outer shell. They could always change that shell as they needed.

A Dead Man's Skeleton was man-made, while a Wanderer Skeleton was created naturally.

As a start, a Wanderer Skeleton usually possessed a stronger soul. However, its final strength still depended on chances and luck.

"Is this a Wanderer Skeleton?"

Angor looked up at the serpent. He was quite certain that the serpent was also confused by what had happened.
