Did you play through the Dawnguard DLC and think "I can't wait to get a GOD LIKE bow and then finally get it and realise that it's the same damage as a glass bow?  Did you slowly feel parts of yourself die off?  If you answered yes like me than this mod is for you.  This mod increases the damage to 21 which is 1 damage better than a dragon bone bow.  No longer do you have to carry around a crappy version.  I have not changed the quest or appearance just the damage.  Note the damage will be higher than 21 when you get it depending on your skill at archery.  If you're wondering why it is roughly 0MB in size that is because it is a very small mod, it only took about 15 seconds to make.
This requires Dawnguard, big surprise I know.
