You gain a +1 bonus to hit with ranged attacks within 15 meters, and your ranged weapons deal +1[W]. (A weapon that deals 1d6 damage per hit will deal 2d6 damage per hit instead, while a weapon that deals 2d8 damage per hit will deal 4d8 damage instead. This affects the base dice associated with a weapon any time they are rolled, including critical hits.) While wielding Longbows and Shortbows, you gain +1 Critical Threat Range.
Notes
The notation '[W]' stands for your base weapon damage. So 2[1d6] if base is 1d6 or 2[2d4] if it is base 2d4. This essentially means your ranged weaponry will deal double base damage within 45 feet. See weapon dice multiplier.
