Manual of Quickness of Action

The Manual of Quickness of Action is a magical book that, read over the course of 48 hours in six days, increases one reader's dexterity. After use, the manual loses its magic but regains it in a century. For 1500 gold at Gilmore's Glorious Goods, Vox Machina acquired this book which, during their travel on Deera, Percy read. Percy and Keyleth donated the used copy to the Cobalt Soul to gain access to their library at the Cobalt Vault in Vasselheim.
