Musketeer

Source Ultimate Combat pg. 38
Some cavaliers are entrusted by their masters with the care and use of expensive and powerful oddities—firearms. Capable of inflicting shocking amounts of destruction without the aid of magic, these musketeers lead the advance of their troops, firing devastating fusillades long before the enemy can prepare for the armed charge that follows.

Weapon and Armor Proficiency: A musketeer does not gain proficiency in heavy armor. Musketeers are proficient with all simple and martial weapons, and with firearms. A cavalier’s levels stack with any fighter levels he possesses for the purpose of meeting the level prerequisite for feats that specifically select a firearm, such as Weapon Specialization.

Gifted Firearm (Ex): At 1st level, a musketeer is gifted by his order with a firearm (either a pistol or a musket). This weapon is both a symbol of the cavalier’s duty and a focus for much of his talent. He cannot sell this weapon. He also gains the Gunsmithing feat.

Beginning at 8th level, the musketeer can focus himself when wielding his gifted weapon. As a standard action, he can focus himself to gain a number of benefits for 1 minute per cavalier level. The musketeer can use this ability twice per day, plus one additional time per day for every four levels beyond 8th, to a total of five times per day at 20th level.

At 8th level, the cavalier gains the benefit of the Improved Critical feat. At 11th level, he can reduce the misfire chance of his weapon by 1 (to a minimum of 1), and at 17th level, the musketeer can double the range increment of his weapon. The reduction of the weapon’s misfire chance and the doubled range increment abilities don’t stack with the similar benefits of the reliable and distance magic weapon special abilities.

Finally, at 20th level, during a period of such focus, the musketeer can engage in a flurry of gunfire. The cavalier can expend one of his daily challenges to make a full attack with his firearm. The musketeer ignores the normal load times for his weapon, but must still expend enough doses of powder and enough bullets to complete each attack.

If the musketeer’s gifted firearm is destroyed, the cavalier loses this ability for 30 days while a replacement weapon is crafted for him. During this 30-day period, the musketeer takes a –1 penalty on weapon and damage rolls. This ability replaces the standard cavalier’s mount ability.

Swift Powder (Ex): At 4th level, the musketeer gains Rapid Reload (musket) or Rapid Reload (pistol) as a bonus feat. At 14th level, each time the musketeer issues a challenge, he may reload a wielded firearm as a free action. This ability replaces expert trainer.
