Version 1.0.81.0
I have 3 ability points in the Bow skill (+30% damage). However, the damage calculated only accounts for +10% bow damage. As far as I can tell, this seems to bug just on the Heartseeker bow. I have compared it with another bow and the damage is calculated with a bonus +30% bow damage.

http://imgur.com/0bhJekYOn a sidenote, I think there should be more transparency on how damage is calculated (for example, the elemental/tenebrium damage is not shown on the tooltip--only physical damage is. Tenebrium bonus damage from ability points on the tenebrium skill is not shown either). Unless my math is terrible (not implausible), I can't seem to calculate the damage as shown for the second bow and even the damage for my other characters.
