Your aim is too good to deal minimum damage.
Benefit: You have deadly accuracy with your agility-based weapon attacks. When dealing damage with a weapon to which you add your Dexterity to your attack rolls (all ranged weapon attacks, and melee weapon attacks made with Weapon Finesse), you can reroll any result of 1 on your weapon’s damage dice. Only weapon attacks that require an attack roll benefit from this feat. You must keep the result of the reroll, even if it is another 1.
