Redirecting Shot 
Feat 10
Source Pathfinder Guns & Gears
Trigger An ally misses with a ranged attack that uses a thrown weapon or ammunition. The ally must be willing to accept your assistance, you must see the attack's target, and the attack's target must be within the first range increment of your firearm or crossbow.
Requirements You're wielding a loaded firearm or crossbow.
Seeing your ally's attack about to go astray, you fire your weapon to right its course. Discharge your firearm and roll a d20. Your ally uses this roll instead of their own, and the attack ignores bonuses the target would gain against the attack from lesser or standard cover.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
FortuneA fortune effect beneficially alters how you roll your dice. You can never have more than one fortune effect alter a single roll. If multiple fortune effects would apply, you have to pick which to use. If a fortune effect and a misfortune effect would apply to the same roll, the two cancel each other out, and you roll normally.
GunslingerThis indicates abilities from the gunslinger class.
