The Librarian returned with a Totem Ranked Magic Demon that Karl vaguely recognized from the Garden Party at the Castle.
"Oh, Overlord Karl. You can make skill books? How fortunate. I had thought your skills might be limited to Runic Items." The Demon greeted him.
Karl checked the name using his system interface before responding.
"District Overseer Rashid, it's a pleasure to see you again. Skill Books aren't really my specialty, but I do have the ability to make a few per month, on skills that I already know. A curious System Skill intended to help advance my team.
I brought you an interesting skill today, I believe." Karl replied.
"Indeed. There is not a single copy registered to the Library with that Skill name, so I came to see if it had been misreported.
But it is correct. And the restrictions are not as harsh as I had feared, given the names. Though, it's a bit insulting that it considers all horned or feathered demons to be compatible with a skill for beasts.
