Ratfolk warfare often occurs in cramped, claustrophobic spaces such as the ratfolk's own underground warrens and heavily trapped gulch fortresses, or the subterranean tunnels of goblins and similar foes. Since these battlegrounds often have tight corners and few areas with long lines of sight, those ratfolk who seek to master the use of firearms almost inevitably become experts in close-quarters combat. These gulch gunners often specialize in proficiency with a single pistol (easily handled in tight spaces) and wander from warren to warren selling their tunnel-shooting skills to the highest bidder.
A gulch gunner has the following class features:
At 1st level, a gulch gunner gains grit as a standard gunslinger. However, the close-combat focus of the gulch gunner results in a slightly different set of circumstances for regaining grit.
Daring Adjacent Shot: The first time each round the gulch gunner makes a ranged firearm attack against an adjacent foe and provokes an attack of opportunity, she regains 1 grit point. Making an adjacent firearm attack against a helpless or unaware creature or on a creature that has fewer Hit Dice than half the gulch gunner's character level does not restore grit, nor do ranged attacks using some ability that prevents the gulch gunner from provoking an attack of opportunity.
A gulch gunner has some unique deeds, which replace some of the standard gunslinger deeds as listed in each entry. These deeds follow all the general rules and restrictions of gunslinger deeds.
Flash and Shock (Ex): At 1st level, the gulch gunner can take advantage of the flash and sound of a firearm to throw off an attacker's aim at close range. When she makes an attack against a foe within her firearm's first range increment, she may spend 1 grit point to gain a +4 circumstance bonus to AC against that opponent until the beginning of her next turn. She can only perform this deed while wearing medium, light, or no armor, and while carrying no more than a light load. This deed replaces the deadeye deed.
Powder Burns (Ex): At 3rd level, the gulch gunner learns to maximize the damage dealt by a firearm at extremely close range. When the gulch gunner successfully hits an adjacent foe with a ranged firearm attack, she may spend 1 grit point to deal an additional 1d6 points of fire damage from the muzzle flash of her weapon. The target must also make a Reflex save (DC 10 + 1/2 the gulch gunner's level + the gulch gunner's Wisdom modifier) or catch on fire. This deed replaces the pistol whip deed.
Staggering Shot (Ex): At 15th level, when the gulch gunner hits an adjacent target with a ranged firearm attack, the target must also make a Fortitude save (DC 10 + 1/2 the gulch gunner's level + the gulch gunner's Wisdom modifier) or be staggered for 1d4 rounds. This deed replaces the menacing shot deed.
At 9th level, a gulch gunner can press her firearm directly against a vulnerable location of an adjacent target, dealing additional damage. When the gulch gunner successfully hits an adjacent target with a ranged firearm attack, she deals +1d6 points of damage. This damage increases to +2d6 at 13th level and to +3d6 at 17th level. Creatures immune to precision damage, critical hits, or sneak attacks do not take this additional damage.
This ability replaces the gun training ability gained at 9th, 13th, and 17th level.
