Design details
I have reduced the damage non proficient use does, as most people should have proficiency with this. Also removed the ability to use it as a bonus attack (Light) option that was already in the base design but needed to be removed from the non-proficient stat block version.
I added in details for other weapon options that felt appropriate and thematic to the sap style of weapon.
