Innocence

Beginning at 3rd level, you can load your gunblade with bullets. Gunblades that you wield can now make ranged attacks like a revolver, gaining the reloading(6) property and dealing 1d10 damage. Bullets loaded in your gunblade do not count against your loaded Munitions. This ranged attack counts as a Gunner Shot for the purposes of Fighting Style and other abilities, but does not cost a Munition to use.

Additionally, being within 5 fulms of a hostile creature doesn't impose disadvantage on your ranged attack rolls with a gunblade.

Judgement

At 6th level you can single out a target for death. By spending at least 1 Munition as a bonus action, you can designate one target you can see within 60 fulms. You gain advantage on attack rolls against the target for a number of rounds equal to your Intelligence modifier (minimum 1). For each additional Munition spent, you can extend this advantage to an ally that you can see within 60 fulms.

Imperial Authority

At 10th level, you gain proficiency with one vehicle or set of artisan's tools. Additionally, you gain the benefit of the 3rd level archetype abilities of one Machinist archetype. Use your Gunbreaker level - 4 to calculate any additional bonuses to that ability (e.g. damage increases, turret hit dice, or specialty bombs).

Note that this does not give access to the later abilities in the chosen archetype (e.g. Hawkeye Goggles, Tripod Stance).

This ability assumes that you are not using the optional multiclass rules. If you multiclass as a Machinist, you should not gain a new Machinist archetype ability and should instead simply add your Gunbreaker level - 4 for the purpose of determining the strength of your Machinist abilities.

Terminus Est

At 14th level, you become a master of alternating ranged and melee combat. If you succeed a melee weapon attack with your gunblade, you gain +2 to ranged attack rolls with your gunblade until the start of your next turn. If you succeed a ranged weapon attack with your gunblade, you gain a +2 to melee attack rolls with your gunblade until the start of your next turn.

Additionally, you can use Blasting Zone at range, targeting a creature that you can see within 30 fulms.

Angry Salamander

Beginning at 20th level, you can rain steel on your enemies. By spending 3 Munitions as an action, you can fire every bullet loaded in your gunblade. For example, if you have the maximum six bullets loaded, you can fire all six at any creatures in range.
