TPOM's Grimarillion Build Compendium, Featuring Pets

I have a few leftover builds that don’t have a class feature, but I want to make sure all the summon pet skills in this game are accounted for:

Build Objective: To make Dracarris feel like a unique and build-defining item while making use of the Core Dweller.

Source of RR:
Black Star of Deceit - 15 flat RR
Earth Ring of Flame - 20 Chaos RR
Eldritch Fire - 35 Chaos RR
Symbol of Solael - 10 Chaos RR
Fiendgaze Tome - 10 Chaos RR
Total RR - 90 Chaos RR

Along with Zunimassa Witch Doctor + Storm, this was one of my first build concepts, spanning out to last September. It had served me well getting through initial testing, but multiple nerfs to several items forced me to reimagine this build somewhat. The concept was a simple one: convert 100% of both Physical and Fire damage to Chaos for full Chaos Swarmlings, with help from 22/12 Hellfire Hellhound and tanking assistance from the Core Dweller. Dracarris was first used in DaShiv’s Pyromancer, where he used Demolitionist’s Fire abilities to reliably proc the Hellspawn ability and grant further Fire damage to pets. Here we focus on the Chaos side of it, as thanks to Earth’s buff, we don’t just convert pet Fire to Chaos, but player damage as well. The main skill we use to proc this ability is Earth’s Meteor - an ability with massive flat damage which if we could bring to 16/16 (maybe by reducing Core Dweller investment), we would. Meteor is bound to Time Dilation - the skill cooldown activates when the Meteor lands, so as the Meteor descends, you can activate abilities like Blood of Dreeg and Core Healing and have their cooldowns reduced as well.

This build gets a nice buff with Fallen Gods: As you can see in the screenshots, you only have around 2650 OA with permanent buffs + Blood of Dreeg; that’s not very reliable to Crit bosses and 25 RR is bound to Crits (Black Star and Fiendgaze Tome). The Mystical Vestments of Severed Faith gives you an extra 100 flat OA, and while you do lose about 140% Pet Damage, that is partially made up by the 21 flat Chaos damage given to your pets. Pierce Resistance is hard to come by on this build, so the new Chestpiece is especially welcome since it grants that resistance. As an additional bonus, you gain about 100% Chaos damage yourself, which will definitely help getting the kills necessary to proc Hellspawn. Now that Fiendgaze Tome converts 100% Cold to Chaos damage, you can also use the Bonescavenger Gloves for even higher player OA and more pet damage to partially offset the loss of Fiendmaster. As for other equipment, the nerf to Voidwhisper rings means that you now have to equip both rings in order to have full 100% Physical to Chaos conversion; Peerless Eye is surprisingly one of the best options for the amulet even with the boon of All Skills amulets you have access to; and the head gear, while surprising to see from a pet build, has the best combination of resistances, damage bonuses, and skill points - even more valuable as the usual sources of Satyr craft are all taken.
