Prerequisite: Requires proficiency with simple or martial ranged weapons.
You have mastered the art of keeping cool under fire. You gain the following benefits:
• Increase your Dexterity score by 1, to a maximum of 20.
• While you are behind half or three-quarters cover, you gain a bonus to saving throws against being frightened. This bonus equals the bonus AC granted by the cover.
• While you are behind half or three-quarters cover and a hostile creature misses you with a ranged weapon or spell attack, you can use your reaction to make one ranged weapon attack against the attacker. If this attack hits, add your proficiency bonus to its damage. You can use this ability a number of times equal to half your proficiency bonus (rounded down) per long rest.
