Hack And Slash Adventure was an old tabletop rulebook from the Grand Library Ashurbanipal.
Ainz Ooal Gown discovered a copy of this game whilst secretly returning his business books in the library. He attempted to use it to relax and at the same time educate the Floor Guardians on humanity.
Hack And Slash Adventure was an original work, though the copy in Nazarick is an adapted version using YGGDRASIL lore and mechanics.
- The title Hack And Slash is actually a generic term for tabletop adventure games.
- It is suspected that Tabula Smaragdina added it to the library in Nazarick once its copyright expired in the real world.
