Empty Quiver Style (Combat, Style)Source Weapon Master's Handbook pg. 14
You can fight in melee with your bow, crossbow, or firearm.
Prerequisites: Weapon Focus with the chosen weapon.
Benefit: While using this style, you can make melee attacks with the chosen weapon as if it were a heavy mace (or a light mace for melee attack made with a hand crossbow or one-handed firearm), though you don’t automatically threaten the area around you as if you were wielding a melee weapon. You can switch between melee and ranged attacks with this weapon without penalty, even during the same round. In addition, you ignore the elf prerequisite for the Stabbing Shot featAPG. If you have the Stabbing Shot feat, you can use it with a crossbow or firearm, substituting a loaded bolt or firearm ammunition for an arrow.
Special: In addition to the chosen weapon, a character with this feat and the weapon training (bows, crossbows, or firearms) class feature can use Empty Quiver Style with any bow, crossbow, or firearm, respectively.
