UPDATE: Contrary to what was assumed before, Conduit Pylon is probably not affected by elite damage - so the diamond in some support character's weapon in Season 5 was pretty much useless, at least if it was for this particular purpose. Thanks to zbyxzh on Reddit who not only found this out, but also reported the exact numbers of how to calculate the Conduit Pylon's damage!
Due to the quick topping out of followers CHD and their low CHC I usually toss in a Topaz for some thorns damage. I figure if they're gonna get hit, why not take advantage of it?
