Redirected Shot (Combat, Grit)Source Inner Sea Combat pg. 17 (Amazon)
You can redirect your allies’ poorly aimed ranged attacks with incredible accuracy.
Prerequisites: Amateur GunslingerUC or the grit class feature, Deadly Aim, Point-Blank Shot, Precise Shot.
Benefit: As long as you have at least 1 grit point, after an ally has made a ranged attack roll but before the results of the roll have been revealed, you can fire a loaded firearm at the volley as it moves toward its target, redirecting its path. Make an attack roll using your highest attack bonus, and use your result in place of your ally’s original attack roll. On a successful hit, your ally’s attack deals damage as normal. You may perform this action a number of times per round up to your Wisdom bonus (minimum 1).Source Weapon Master's Handbook pg. 25 (Amazon)
By spending 4 stamina points, you can use this feat an additional time per round.
