Immaculate accuracy

Through thorough training with your way of fighting, you become more capable of capitalizing upon multiple opportunities in combat at once.

• Increase one ability score by 1, to a maximum of 20.
• Whenever you make an attack roll using the ability score increased by this feat, with advantage from more than one source (cannot be from flanking) and no disadvantage, you may reroll one of the dice once.

This feat does not stack with elven accuracy. Stick to your uppity better one elves!
