The Way of the Sniper gets Covered Reload:
You duck into a safe position or minimize your profile while reloading to make your next attack. Either Take Cover or attempt to Hide, then Interact to reload. As normal, you must meet the requirements to Take Cover or Hide; you must be prone, benefiting from cover, or near a feature that allows you to Take Cover, and you need to be benefiting from cover or concealed to a creature to Hide from that creature.
Gunslingers have the Fake Out feat:
Trigger: An ally is about to use an action that requires an attack roll, targeting a creature within your weapon's first range increment.
Requirements: You're wielding a loaded firearm or crossbow.
With a skilled flourish of your weapon, you force an enemy to acknowledge you as a threat. Make an attack roll to Aid the triggering attack. If you dealt damage to that enemy with the same weapon since the start of your last turn, you gain a +1 circumstance bonus to this roll.
Fake Out also has the Visual trait:
A visual effect can affect only creatures that can see it. This applies only to visible parts of the effect, as determined by the GM.
How would these two skills interact?
- If you Hide as a part of Covered Reload and succeed you would no longer be observed. Would this prevent you from being able to use Fake Out on the enemy you are hidden from since it has the Visual trait?
- Assuming you can use Fake Out does the flat-footed penalty the enemy has from you being hidden apply to the attack roll made to aid?
Any other details I'm missing about how these would combine?
