Atlas Tree in this run is now outdated.
Build is also outdated. If I were to do this run again I would probably go Trickster and Necromancer with Flesh Offering. Both Raider and Gladiator have been nerfed and are not ideal anymore.

We can also use Reap now since it's easy to get 3 stacks of the Exsanguinate debuff onto bosses.
Reap + Controlled Destruction + Brutality + Cruelty
Once you have the sockets and colors for a 4-link Corrupting Fever
Corrupting Fever + Efficacy + Brutality + Swift Affliction
Gear Progression
Look for +1 Physical Skill Gem Wands and/or Physical DoT Multi. If you get one with an open Prefix you will be using that for the entire Exarch&Eater run. You want to pick up unidentified Rares early on for Resistance crafts. You also need to sell some identified rares so you can craft the Spell damage recipe onto your wand in case you do not get a wand with good prefixes.
In Merciless Lab you want to farm Exsanguinate of Transmission or just buy it. Transfigured Exsanguinate has built-in Chain as well as a lower base cast time and higher base duration. This comes at the cost of lower hit damage and damage effectiveness but these stats are not important for us. You can also farm quality for your Exsanguinate but I do not think it's absolutely necesssary.
Once you enter maps or early maps you are looking to have a 4-Link for all your damaging skills. Also, if you did not get physical dot multiplier unveil and you do not have it on your wand yet in the campaign I recommend doing Jun Missions and/or picking the Keystone "All Hands".
