Class Mechanic – Soul Shards

Soul Shards is the Warlocks unique class mechanic allowing you to bind yourself to a Soul Shard Greater Demon that will fight beside you. They come with a variety of different effects as well as on-use-abilities to help you on the battlefield.

Below you’ll find the recommended Soul Shard Demon to bind for this build.

  • Legion Shard – Grants the skill Summon Ae’grom who will consistently spawn Lesser Demons on the field for you and blow them all up with his on-use-ability for massive damage output.
  • Spawn Fragment – This makes Ae’grom spawn Vile Child Lesser Demon every 1 second. When you summon a Greater Demon this increases the spawn rate by 50% for 4 seconds up to 150%!

Gear, Gems and Stats

The following sections cover the important systems that are essential to improving the power of your character in the endgame of Diablo 4.

Legendary Aspects

Each aspect is listed with its matching gear slot. Do your best to keep each aspect in the assigned slot. Aspects placement is planned with potential Unique and Mythic Unique gear upgrades in mind for easiest and cheapest transition. Obol gambling is a great way to try to obtain specific slot Legendary Aspects and even Uniques early. For exact Runewords suggestions, see here.

Season Mechanics

Splinters of Evil

In Season of Hell’s Legacy, one of seasonal powers will consist of the three Splinter of TerrorSplinters of Prime Evil, acquired by completing seasonal questline and defeating echoes of Diablo beneath Tristram Cathedral, Baal at Arreat Summit, and Mephisto within the Durance of Hate. Splinter of Evil trigger iconic Prime Evil area of effect damage abilities and alter actitivies associated with the Prime Evil.

Main consideration for first Splinter of Evil choice is expected to be in activity modifiers. Only one Splinter of TerrorSplinter of Prime Evil can be used at a time, but there is a mechanism to change. Due to Helltide being the most common early progression activity, it is recommended to use Splinter of TerrorSplinter of Terror first.

Duplicitous Soul Splinters

The second layer of seasonal powers consists of Duplicitous Soul Splinters gems, like Abyssal Splinter of HellfireAbyssal Splinter of Hellfire, to be slotted into jewelry and the newly introduced Leoric's CrownLeoric’s Crown helm. You can equip up to three Abyssal Splinter of AnguishSoul Splinters among available Jewelry slots.

Duplicitous Soul Splinters gems provide sizeable buffs to some stats at the price of heavy penalties to others. One should be careful at making choices to either ignore the penalty – Damage over Time builds do not care about losing Critical Strike Chance, for example, or compensate it.

Recommended Duplicitous Soul Splinters setup to can be looked up in Gems and Runewords.

Diablo II Runewords Gear

In Season 15 some Diablo II runes, like RalRal or IthIth were reintroduced for the season, as the cherry on top. While being not impressive on their own – they can be used to craft new Unique gear piece by combining certain runewords and Normal “white” item base inside Horadric Cube. There are few the most impressive outcomes, like EnigmaEnigma (Jah Ith Ber), SpiritSpirit (Tal Thul Ort Amn), GriefGrief (Eth Tir Lo Mal Ral) or InfinityInfinity (Ber Mal Ber Ist). Ancestral version of item base will produce the Ancestral version of Unique.

Talismans

The Lord of Hatred expansion introduces Talismans as a new character progression system. You get to equip a Seal and place Charms into its slots for a massive power boost. The recommended setup for the Abaddon Summoner Warlock build is listed below:

  • Seal – 6 Charm slot with Critical Strike Multiplier is the best or with any other damage multiplier. Best set for this build is “Chains of Horazon”.
  • Charms – Demonology Ranks, any defensive stats or All Stats should be the prio here. Make sure you get the 5 set pieces of the “Chains of Horazon” set and the last one is optimal as Scepter of the ThreeScepter of the Three.

Mercenaries

During the Vessel of Hatred campaign, you will unlock Mercenaries to assist you. While you can choose freely early on, we recommend Raheir as your main merc:

For the reinforcement, stick with Varyana, utilizing her BloodlustBloodlust to trigger when any Skill is cast in combat.

Rotation and Build Mechanics

The build focuses on summoning a large army of demons to fight for you before overwhelming the enemies with our most powerful greater demon skills. This keeps enemies at bay allowing you to cast Bombardment freely from a safe position during a fight. Sigil of Demons will pop up a hellworm that will copy your casts further pushing the growing army playstyle.

Rotation and Playstyle

  1. Nether StepNether Step – Used for increasing general clear speed and to get out of harms way.
  2. Sigil of SubversionSigil of Subversion– Applies Hex on enemies for better damage as well as suvivability.
  3. Sigil of SummonsSigil of Summons– Gives your Lesser Demons a damage boost and helps us keep demons actively rolling for paragon legendary node “Fathomless”.
  4. Fiend of AbaddonFiend of Abaddon– All your Dominance should now be spent on this skill for his incredible damage output.
  5. Command Ae’grom – This guy needs to be on the field at all times to spawn your Lesser Demons and using his command skill to blow them up.
  6. BombardmentBombardment– At this point we’ll be spamming Bombardment as long as we are behind our army of demons. The Sigil of Demons will be mimicking the casts once it activates which is VERY quick and every 200 demon we get a free demon summon which goes straight back into the Fiend of Abaddon.
  7. Important note – Abaddon is an expensive cast, and generally with a free cast you can get two out at once; once free, once at 30 Dominance. This doesn’t always line up but more often than not you’ll see this happen. Your Demon summon icons glow when you have the free cast available!
