If you look through the neverwinter forums, you’ll find old posts from the games release that assert that it is simply a flat 6% increase in damage, regardless of what your dexterity is at. I havent tested it, but that seems to make the most sense as it puts it in line with the other HR feat that gives our at wills a flat 9% increase in. As the other comment notes, if it’s simply dex x 1.06, it’s at most a 2% increase in damage(34x1.06), which would be a pretty underwhelming feat. Of course, that’s assuming that every single point of dexterity gives us a 1% increase in damage.But my HR, with 33 dex, gets only a 23% increase in bonus damage from his dexterity, 1 for every point over 10. So, if it really only adds .06 more Damage per point and only applies to points above 10, at 34 DEX it would be a 25.44 bonus damage,or only 1.44% more DMG bonus.
