History
For 1500 gold at Gilmore's Glorious Goods, Vox Machina acquired this book which, during their travel on Deera, Percy read. In Westruun, after Scanlan offered Keyleth the similarly expended Tome of Leadership and Influence, Percy jokingly offered her the Manual of Quickness of Action, but then said that he actually hoped to sell it to someone who could reasonably be expected to live at least a century more. Percy and Keyleth ultimately donated the used copy to the Cobalt Soul in order to gain access to their library at the Cobalt Vault in Vasselheim.
