The bushwhacker specializes in the art of the ambush. For her, gunplay works best when it comes from a concealed position and is directed against a target that falls with the very first volley and is dead before the smoke clears.
A bushwacker has the following class features:
At 1st level, at the start of each day, a bushwhacker gains grit points equal to her Wisdom modifier – 1 (minimum of 1). In addition to all the ways any gunslinger can regain grit, a bushwhacker who reduces a helpless or unaware opponent to 0 hit points or fewer also regains 1 grit point. This expands the way in which the bushwhacker gains grit points, so a bushwhacker who gains grit points in this way only gains 1 grit point for reducing a helpless or unaware opponent, not 2 grit points.
This otherwise works like the gunslinger's grit ability and alters that ability.
A bushwhacker replaces some of her deeds with the following deeds.
Shifty Shot (Ex): At 3rd level, a bushwhacker with at least 1 grit point deals 1d6 points of extra damage when using her firearm to attack opponents denied their Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not). Except for the requirement that she must use a firearm and must have at least 1 grit point to use it, this deed otherwise works identically to a rogue's sneak attack class feature (including the requirement that she must be within 30 feet of her target to deal this extra damage), and stacks with the sneak shot ability (see below) and sneak attack. This deed replaces the utility shot deed.
Long Range Shifty Shot (Ex): At 7th level, a bushwhacker can double the range at which she deals extra damage from a sneak attack or shifty shot (from 30 feet to 60 feet) with a firearm by spending 1 grit point. When she spends this grit point, she must still have at least 1 grit point left to deal extra damage from shifty shot if she is using this deed. This deed replaces the targeting deed.
This ability otherwise works like the gunslinger's deed ability and alters that ability.
At 4th level and every four levels thereafter, a bushwhacker deals 1d6 points of extra damage when using a firearm to attack opponents who are unable to properly defend themselves. Unlike with the shifty shot ability, she deals this extra damage regardless of whether or not she has any grit points when making the attack. Except for the requirement that she makes a firearm attack, this works identically to a rogue's sneak attack class feature. This extra damage stacks with sneak attack and the damage from shifty shot.
This ability replaces the bonus feats the gunslinger gains at 4th, 8th, 12th, 16th, and 20th level.
