I have searched several different areas and have yet to find anything clearly defining the damage of arrows. What better place to discuss it then here? Now before you roll your eyes and go "Duh" you would be surprised at how many do not really understand the damage effect of arrows on a class. I can't even confirm that I do myself but I'm willing to leap in and start the discussion so we have one post that can help someone out in the future with these questions. Here goes.... Currently we see the damage of titanium (t9) at +123, we see damage of Spirit-blessed (specialty T9 arrows) at +209. My theory is the formula in its most simplistic form is this: (class/skills+procs)+arrow damage. The arrow damage itself remains constant. The boosts to the arrows can help with range and with hitting the mark but the damage is the same no matter the class or the skill set. If I'm incorrect it would be wonderful to find this out now.
