Master Gun Proficiency

Increases Focus by 3, decreases target's Evade by 3, and increases total gun damage by 1d10. All shots automatically deal 10% piercing damage to Vitality which can be increased by (added to) any piercing effects or armor piercing bullets. Misfire range drops by 1 but will not decrease to less than 1 (locks that never misfire are unaffected). Clearing a misfire costs no action, and the gun remains loaded. This does not reduce or override the misfire ranges set by the Overcharge skills. Your attacks will also daze targets for 1 round with each attack.

Master Rune Cannon Proficiency

Decreases target's evade by 3 and increases base rune cannon damage by 1d12. Soul Cost to fire rune cannon is halved, rounded down. All shots automatically deal 10% piercing damage to Vitality which can be increased by (added to) any piercing effects.  Rolling a natural 20 on skill's activation doubles the evade penalty and the 1d12 extra damage result as well as increasing the damage by your Arcana score.

Advanced Gun Proficiency

Increases Focus by 1, decreases target's Evade by 2, and increases total gun damage by 1d8. Misfire range drops by 1 but will not decrease to less than 1 (locks that never misfire are unaffected). This does not reduce or override the misfire ranges set by the Overcharge skills. Your attacks will also daze targets for 1 round with each attack.  Rolling a natural 20 on skill activation stuns the target for 1 round and dazes the target for the following 1d4 rounds once the target comes out of stun. The target can be stun-locked with each shot, with the daze taking place afterwards.

Novice Gun Proficiency

Decreases target's evade by 1 and increases total gun damage by 1d4. Your attacks will also daze targets for 1 round with each attack. Rolling a natural 20 on skill activation stuns the target for 1 round and dazes the target for the following 1d4 rounds once the target comes out of stun. The daze duration does not stack. The target cannot be stun-locked, the 1d4 rounds of daze must play out before the same target can be stunned again. This is a Support Action skill, but it can be activated as part of the Support action used to fire your gun.

Basic Gun Proficiency

Decreases target's evade by 1 and increases total gun damage by 1. This is a Support Action skill, but it can be activated as part of the Support action used to fire your gun. On the turn you activate it, no other skills can be chained to that shot.
