Story from Within
5'10", 120lbs, Silver eyes, grey-blue skin, Silvery-blue haired, Elf.
Magic Bow: You gain a +1 bonus to attack and damage rolls made with this magic weapon. The range of the weapon is doubled both in normal and long.
A masterwork weapon, no matter what that weapon is, gets a +1 enhancement bonus to attack, NOT to damage. Arrows were no exception.
Masterwork arrows and magical bows STACK with the bonuses from masterwork and magical bows for attack – meaning you could have a +5 bow and a masterwork arrow, and get a +6 to attack and +5 to damage.
