A bushwhacker replaces some of her deeds with the following deeds. This ability otherwise works like the gunslinger's deed ability and alters that ability.
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.
