Flanged Mace

The Flanged Mace was a blunt weapon obtainable by Ezio Auditore da Firenze during the 15th and 16th centuries. It could be purchased from any blacksmith in Florence, Venice, Forlì, San Gimignano, or Monteriggioni. During his attempt to erode the Borgia's power, Ezio could acquire the weapon from guards.
