Ae'grom Summoner

A demon that breeds smaller demons, which you blow up. The safest Warlock and the cheapest to gear, and the weakest of the three.

01 — The idea

How the engine works

The Legion Shard's Ae'grom spawns a Vile Child every half second with the Spawn Fragment. When the counter on the skill reaches 10 Lesser Demons, you press Command Ae'grom and they all explode. Bombardment, Command Fallen and Sigil of Summons make and kill more demons, and every 200 Lesser Demon deaths make your next Greater Demon cast free. You spend those free casts on Tortured Wretch: Punching Bag, which takes your damage for you while you stand in its area. Metamorphosis: Destruction Demon runs underneath for Demonform and Volatility.

Who it's for

New players, hardcore characters and anyone who wants a summoner that works with no uniques at all. It is the lowest rated of the three Warlock builds: safe general farming, not a Pit pusher and not a fast clearer.

The bar

This is the finished bar. A fresh 70 runs Nether Step in Bombardment's slot, and the speed-farm version does the same.

Command Ae'grom

Free from the Legion Shard. Ae'grom cleaves and breeds on his own. Press the command when the icon shows 10 Lesser Demons to explode them all.

Press — at 10 demons
Tortured Wretch

Rank 15 with Punching Bag, Duration and Cost Reduction. Lasts 12 seconds, absorbs up to 30% of your Maximum Life in damage while you stand in its area, then explodes and Fortifies you.

Keep it up
Sigil of Summons

Rank 15 with Summon Hellwyrm, Cooldown and Damage. After 16 kills it calls a Hellwyrm that copies your Lesser Demon casts. Lesser Demons deal 25% more inside it.

Each new pack
Command Fallen

Rank 15 with Mega Lunatic, Wrath and Dominance. A Basic skill that builds 10 Wrath, and every 15 hits returns a point of Dominance.

Spam — between skills
Bombardment

Rank 15 with Endless Barrage, Damage and Focused Target. Recast every few seconds to keep the barrage at full stacks.

Every few seconds
Metamorphosis

One point, with Destruction Demon, Damage Scaling and Dominance. Cast once for Demonform and Volatility. A second press cancels it.

Keep it up

Passives

No Key Passive and no passive nodes. All 83 points go into active skills, 14 of them from the Season Rank system. Nether Step takes 4 points with Extra Charge, Movement Speed and Shadow Recall for when it is on the bar.

Soul Shards

You bind one Soul Shard and one Fragment: the Legion Shard with the Spawn Fragment. The shard rewards you for cycling demons. Casting a Greater Demon skill speeds up your Lesser Demon skills for 20 seconds, and every 200 Lesser Demon deaths makes the next Greater Demon cast cost no Dominance. Spawn turns Ae'grom into a factory and changes his command from spewing Vile Children to detonating every Lesser Demon you own. The more demons you make and kill, the more free Wretches you get.

PickWhat it gives you
Legion ShardGrants Summon Ae'grom. Casting a Greater Demon skill gives Lesser Demon skills 25% Cast Speed and 20% Cooldown Rate for 20 seconds. After 200 Lesser Demon deaths, your next Greater Demon skill has no Dominance cost.
Spawn FragmentAe'grom spawns a Vile Child every 0.5 seconds and his cleave deals 90% more damage. Command Ae'grom explodes all your Lesser Demons instead of spewing Vile Children.
03 — Gear

What to wear

Nothing here is required. The finished version does wear uniques, and the chest is the one that changes how it plays.

Uniques

ItemWhat it doesPriority
Ae'grom's SchismChest. Ae'grom and his summons deal 120–150% more damage, you summon his other half, and Command Ae'grom gains a second charge. This is the big jump in power, the reason Cooldown Reduction matters, and the first choice for a crafted Mythic.Core
Eye of BaalFocus. Soul Shard skills and their demons deal 60–80% more damage, and each Soul Shard skill cast adds 10% to all your damage for 15 seconds, up to 50%. Second Mythic choice.Core
Seed of HorazonAmulet. Demonology skills deal 0.4–0.5% more damage per point of Wrath you hold, and you take less damage per point of Dominance. It pays you for keeping both bars full.Core
TemerityPants. Overhealing becomes Barrier worth 80–100% of the excess for 8 seconds. Your own demons dying count as kills, so Sadistic's Life on Kill overheals you constantly.Core
Leoric's CrownHelm. Counts as jewellery and boosts its socketed gems by 35–50%. It holds the Black Soulstone and the Splinter of Anguish.Recommended
Wendigo BrandRing. Every 15 kills in the last 50–60 seconds adds 2% damage and 1% Attack Speed. Your demons dying keep the count high.Recommended
The Fecund SealRing. Sigil of Summons deals 100–140% more damage and can summon up to 2 extra Lesser Demons. An option if you lean harder on the Sigil.Variant
Seal of the Diamond MindMythic seal. Lowers the number of charms needed for every set bonus by one, which is what lets you run four of one set and two of another.Mythic

Before they drop

Play the full build from level 70 in legendaries. Craft a Stealth chest and an Ancient's Pledge focus in the Cube, and put Cir + Prid in the helm: Prid casts Dark Prison for you, so put a single point in Dark Prison. Wear Might on the helm, Juggernaut's on pants, Accursed Touch on gloves, Malicious on the weapon, Fiendish Oppression on boots, Aggressive and Remorseless on rings and Demonic on the amulet. Run Slaughter and Survival charms. Survival gives +1000 Armour and +100 All Resistance at two pieces.

Legendary aspects

AspectWhat it does for you
Sadistic AspectAmulet by transfiguration, boots until then. Killing your own demons has a 50–75% chance to count double, toward kills and toward the 200-death free cast, and Life on Kill rises by 1% of Maximum Life.
Malicious AspectWeapon. In Demonform you deal more damage for every demon or enemy Close to you, and you are always surrounded.
Aspect of Fiendish OppressionBoots. Summoning a Greater Demon knocks down enemies around it for 5 seconds, and Lesser Demon skills deal 20% more to crowd controlled enemies. Every Wretch triggers it.
Duelist's AspectGloves, finished build. Stacking damage for one-handed weapons. It replaces Accursed Touch once the talisman handles Vulnerable.
Crushing AspectRing. More damage while Fortified, which exploding Wretches keep up.
Aspect of Accursed TouchGloves, early. Lucky Hit chance to apply Vampiric Curse, which makes enemies Vulnerable.

Heavenly Strength needs a two-hander

Aspect of Heavenly Strength only gives its Damage Reduction while you wield a two-handed weapon. The finished build uses a one-hander and the Eye of Baal focus, so the aspect does nothing there. Only use it if you are deliberately playing a two-handed version.

04 — Numbers

Stats, gems and paragon

Roll and masterwork toward these, in this order.

#StatWhere you roll it
1Maximum LifeNearly every piece, and tempered on armour and amulet
2Critical Strike ChanceWherever it rolls, plus a Gar rune early
3Attack SpeedWherever it rolls, then the talisman's two-piece bonus
4Cooldown ReductionWherever it rolls. It matters once Ae'grom's Schism gives Command Ae'grom a second charge.
5Demonology damage and ranksTempered on gloves, weapon and focus, and ranks on charms
6Movement SpeedBoots, inherent and tempered

Hard targets

Early on: over 30% Attack Speed, over 40% Critical Strike Chance and Maximum Life on nearly every piece. Finished: 100% Attack Speed, counting the two-piece Chains of Horazon bonus, 100% Critical Strike Chance, and as much Cooldown Reduction as you can fit for Command Ae'grom.

Tempering & masterworking

Maximum Life on every armour piece and the amulet. Demonology damage on gloves, weapon, focus and, early on, both rings. Movement Speed on boots. On charms look for ranks to Demonology skills, Maximum Resource and All Stats.

Gems, runewords & Splinters

Paragon

Start board, then Dominion, Demonic Spicules, Dynamism and Fathomless. Dominion is the key: spending Dominance to summon a demon halves the Wrath cost of Demonology skills and adds 80% to all your damage for 20 seconds, and every Wretch triggers it. Fathomless adds 15% per demon summoned in the last 20 seconds, up to 105%, which this build holds permanently. Level Unbound, Eliminator and Demonologist first. Take every glyph to 50 for the radius, then to 100, then 150.

GlyphWhere and why
EliminatorStart board.
Eldritch SightDominion. Vulnerable damage. Level it last.
DemonologistDemonic Spicules.
UnboundDynamism. Level it first.
VanguardFathomless.

Mercenary

While gearing up, hire Varyana and reinforce with Raheir for his Bastion. Finished, hire Raheir and reinforce with Aldkin. On hardcore, use Raheir as your main and Aldkin with Field of Languish from the start.

05 — Getting there

From fresh 70 to finished

Nothing is gated. You play the same build from level 70 and each drop makes it a little stronger.

Fresh 70The whole build, no uniques

Legion Shard and Spawn Fragment. Tortured Wretch, Sigil of Summons, Nether Step, Metamorphosis, Command Ae'grom and Command Fallen. Stealth chest, Ancient's Pledge focus, and Prid in the helm to cast Dark Prison for you.

First uniqueTemerity and Sadistic

With both, every demon that dies heals you past full and the excess becomes Barrier. Destruction Demon's Burn stops being a worry. Swap Nether Step for Bombardment.

The big oneAe'grom's Schism

Two Ae'groms and two charges of the command. Start stacking Cooldown Reduction now.

Build onlineEye of Baal, Seed of Horazon, Leoric's Crown

A one-hander with the Eye of Baal focus, the Seed on your neck, and the Black Soulstone with Anguish in the crown.

FinishedTalisman and Mythic

Four Chains of Horazon and two Rite of the Nameless under the Seal of the Diamond Mind, Sadistic transfigured onto the amulet, glyphs to 150. Craft Ae'grom's Schism as your one Mythic.

06 — Playing it

The rotation

Metamorphosis, once

Don't touch the button again unless the buff wears off.

Summon Ae'grom

He starts breeding straight away. Watch the counter on the icon.

Sigil of Summons ahead of you

Drop it where the next pack is, so the fight happens inside it.

Tortured Wretches

Drop as many as you need to survive and stand inside their area. Use every free cast on one, and try to keep more than 80% of your Dominance in hand.

Command Fallen and Bombardment

Spam Command Fallen between everything else. Recast Bombardment every few seconds to hold its stacks, no more often than that.

At 10 Lesser DemonsCommand Ae'grom at 10

Explode the lot, then let them rebuild.

On bosses

The rotation doesn't change. Keep Wretches under you, keep Bombardment at full stacks and detonate at 10. Save Raheir's Bastion for the boss's big mechanics. Expect long fights: this build has less single-target damage than Blazing Scream or Apocalypse.
