The Gnome Flickmace has been a bane for DMs since the release of Pathfinder 2nd Edition. Even with the most recent errata, it's a powerful weapon -- but most players have probably played it wrong.

Players must have the Ancestry of a Gnome to use the weapon.

This means most characters should be taxed with Adopted Ancestry.
