im not sure this was discussed earlier but ,,,, sigh, Heavensfire and i210 guns (eso and gordian), they all have the same physical damage value at 68 :/

Heavensfire vs Ferdinand:

Ferdinand = WD68, 71crit, 102 ss :x
Heavensfire = WD68, 68cit, 93det

if you are unlucky with A4 drops i would stick with the Thordan gun and give the Gobdip to someone else who might benefit from it more. ; ;
