Source: TSAR Day 1 DLC: And a Gun!
Some samurai understand that in order to master the blade, one must first master strictly better weaponry.
Samurai with a Gun (Ex)
At 1st level, the samurai with a gun gains the gunslinger gunsmith ability, granting them a battered firearm of their choice (blunderbuss, musket or pistol) as well as the Gunsmithing feat as a bonus feat. The samurai with a gun is also proficient with one type of firearm of their choice (most often the same type of firearm chosen with this class feature).
Gritted Teeth, Iron Resolve (Ex)
At 1st level, the samurai with a gun gains the grit class feature, as the gunslinger class feature. The samurai with a gun uses their Charisma modifier in place of their Wisdom modifier for these purposes.
A samurai with a gun must spend 2 grit points whenever they would expend a use of resolve.
In addition to the normal ways the samurai with a gun could recover grit, the samurai with a gun may recover grit the following ways:
- Critical Hit against a Challenged Target: Each time the samurai with a gun confirms a critical hit with an attack against a target under the effects of their challenge ability, they regain 1 grit point.
- Killing Blow against a Challenged Target: When the samurai with a gun reduces a creature to 0 or fewer hit points, and that creature was under the effects of their challenge ability, they regain 1 grit point.
The samurai with a gun does not regain grit points if the creature is helpless or unaware, or has fewer Hit Dice than half of the samurai with a gun’s character level.
This alters resolve.
