Reading the feat from Nethys, I'm having a hard time grasping exactly what damage is dealt.
For sake of argument, say a Ranger is using a longsword/shortsword combo and uses this feat, which activates when Ranger misses their initial attack with longsword - what happens?
Lets say you are playing a level 13 ranger with 20 str. With a shortsword secondary you would deal 8 points of damage. 5 from strength, 3 from weapon specialization.
