does the arcane archer bonus stack with other bonuses? i know a +1 arrow and a +1 bow do not....since every bow (every bow we care about, i loot enough masterwork longbows thank you very much ) is +1 that would make the 1st level useless. and i could get the favor to get +3 deneith returning arrows long before +3 arcane archer. would that mean you'd be dumping in tons of enhancement points just to have +2 at the 5th tier? i know this means i could focus on the bows other properties and not the pluses......except once you get deneith favor. anyone know yet?
