Infernal Mantle and Consuming Dark

Years ago there was a Consuming Dark build but it got nerfed into the ground. I recently got a 6L Mantle and stated thinking maybe I could do something with it. Not finding a lot here so I'm wondering if the two together could pull something with some chaos scaling that I don't know about. Maybe an Ignite thing using Elementalist and Golem tanking (Meat Shield) but I'm crap at building. I don't need 25M Sirus damage but I would like to at least hit hard enough to A8 him before the 25 minute mark in the fight. If there's not a build, no big deal though. Thank's for any advice, I tried the Discord and poe.ninja first but there wasn't any responce.
