The video below shows it’s effectiveness in the Slaughter Shaft. I do show the gear and skill tree. The main items in this build are the Dastardly Seventh Sense and the Ineffable Knowledge artifact, both from Guns Love and Tentacles.
Any questions, let me know! You can also crit swap with the unforgiven, but I feel the Seventh Sense has enough killing power on it’s own to do the job. Oh, and you can only get the Dastardly Seventh Sense in one flavor. There are no anointments that come with it.
