I have a masterwork Subtle Calamity. Now this may sound silly but I noticed the amount gained from the masterwork orange-ish bar did not seem as large as my other masterwork weapons. So I used digital calipers. My bow masterwork measured 4mm. Every other legendary masterwork in my collection measured at 8mm. In addition to this I went to Lightgg to check the item stats and how much the weapon perks add. According to the data they have my bow should have 100 accuracy. My bow is mysteriously missing stat points from the mastery according to Lightgg and my measurements. Or is it just some bug where it does have the 100 accuracy but its not being displayed. UPDATE: Asked in local chat of the traveler if any one else had a masterwork Subtle Calamity I could compare mine to. A helpful player named HumongousEgo equipped his, in addition I asked if he would check out my bow to see if it does seem like it is not getting the correct boost from masterwork. He agreed with me is if definitely either not displaying or giving the correct amount of points for master work. Second UPDATE: I tried switching around the weapon perks. When Straight Fletching is equipped I loose 5 accuracy from masterwork. When I use Helical Fletching I then gain the full 10 accuracy from the masterwork. Bow string type is not effecting the the accuracy gained from the masterwork. Third UPDATE: I just obtained another Subtle Calamity with accuracy as the masterwork. So I maxed the masterwork. It is displaying 7mm measured on the calipers. Something screwy is going on.
