Basically I proved pictures above of the thrill of the hunt bug. Each barbed shot should provide you with 3% critical strike boost on your main stats after firing barbed shot, but I am not getting any critical strike boost. You can get in total of 9% critical strike but it didn't add anything to main stats after using all 3 times and keeping the update of it.
