Bosses
Diablo 4 has bosses you can fight whenever you like, bosses that appear on a clock, bosses that live behind a dozen dungeon doors and bosses you meet exactly once. Our 62 boss pages cover all four kinds, and how often the game offers the fight turns out to be the most useful thing to know about it, because it decides whether a boss is a farm, an appointment or a memory. So this guide runs in that order, from the fights you can repeat at will down to the ones the campaign spends.
One census sits behind the middle of the list. Our dungeon table names the final boss of all 115 Codex dungeons, and 32 of them have none. The remaining 83 doors are shared by a small cast: the Tomb Lord alone guards 13 of them, and eleven bosses between them account for more than sixty. A dungeon boss is not a location so much as a recurring employee.
Whenever you want
Two bosses have no schedule at all. Gaspar Stilbian is a level 35 unique elite standing near the Highland Wilds in Scosglen, neutral until attacked, and our page treats him as a farm: kill him, leave, come back, and he drops Crushed Beast Bones and loot every time. The Butcher is the opposite kind of unscheduled: he appears at random inside dungeons, cannot be sought out, and drops his Cleaver, a unique axe our unique axes page lists for every class. Attack from behind and heal often, the page says, because he does not wait for you to be ready.
Every six hours: the world bosses
Three bosses run on a timer. Our world boss page says one of them spawns roughly six hours after the last one died, in one of five arenas, and neither the boss nor the arena is announced in advance; the in-game notice gives about 30 minutes' warning. The arenas are one per region: The Crucible in the Fractured Peaks, Caen Adar in Scosglen, Saraan Caldera in the Dry Steppes, Seared Basin in Kehjistan and the Fields of Desecration in Hawezar. All three drop Scattered Prisms, the material that adds sockets, and Ashava only begins spawning once the campaign is done.
| World boss | What to dodge, per our page | Notes |
|---|---|---|
| Ashava the Pestilent | Double swipe, charge, poison pools | The first world boss most players meet; her page maps all five arenas |
| Avarice the Gold Cursed | Chest swing, mallet slam and thrust, portal charge, cleave, gold vomit, pillars | Golden lightning marks his arena when he is due |
| Wandering Death | Death Pound, Shout, Tornadoes, Crater, Grasp and Beam | Legendary loot and prisms |
If the icon never appears, our world boss not spawning fix walks through the timer, the region and daylight settings and the usual connection checks.
Behind dungeon doors, as often as you clear them
Eighteen of our boss pages are dungeon bosses, and a dungeon can be run again and again, so these are the fights you will see most. The table counts how many of the 115 dungeons in our master list each boss guards. Where a boss page names fewer dungeons than the table does, both figures are given, because the pages were written before the table was.
| Boss | Doors in the master table | Dungeons our boss page names | The attack to learn |
|---|---|---|---|
| Tomb Lord | 13 | Every location listed on the page | Bone Storm and Bone Wall |
| Scourge of the Land | 8 | Betrayer's Row, Endless Gates, Grinning Labyrinth, Inferno | Double slam, wide swing, demon summon, fire breath; he stands still while breathing fire |
| Resurrected Malice | 8 | Forbidden City, Black Asylum | Spirit balls in three patterns |
| Khazra Abomination | 8 | Champion's Demise, Komdor Temple, Hoarfrost Demise, Broken Bulwark | Poison and charges |
| Blood Bishop | 7 | Sanguine Chapel, Hallowed Ossuary | Projectiles, blood clot mines, Bloodsucker |
| Mother's Judgement | 4, plus the Whispers from the Past story fight | Yshari Sanctum | Exploding red circles; she teleports to the furthest one |
| Knight Council | 3 | Light's Refuge, Heretics Asylum, Maugan's Works, Kor Valar Ramparts | Kill the Sacred Physician first |
| Broodguard | 3 | Defiled Catacombs | Mulch, web spray, brood call |
| Drowned Seahag | 3, plus one row spelt Seaheg | Ghoa Ruins | Geysers and club swipes |
| Seething Hivemaster | 3 | Collapsed Vault, Shivta Ruins | Scythe slash, Bugstorm, spitballs, swarm call |
| Bramble | 3 | Jalal's Vigil | Poison gas and toxic pools |
| Chief Marauder | 2 | Earthen Wound, Bloodsoaked Crag | Axe swings; one of the easier bosses |
| Outlaw Sharpshooter | 2 | Cutthroat's Escape | Smoke bomb, stun trap, explosive shot |
| Den Mother | 2 | Light's Watch, Aldurwood | Claw slashes and red miasma |
| Spiritcaller of Frost | 2 | Derelict Lodge, Lost Archives | Triple iceball |
| Spiritcaller of Flames | 2 | Garan Hold | Fireball towers, triple fireball, Fallen resurrection |
| Spiritcaller of Squalls | 2 | Whispering Pines, Wretched Delve | Lightning |
| Slither | 2 | Forgotten Ruins, Witchwater | Acid spit, poison ray, eye laser, Nangari Viletooth |
| Sarat | 1 | Sarat's Lair | Web spray and poison balls |
The gap between the two columns is itself information. Our Khazra Abomination page lists four dungeons and the table finds eight, Resurrected Malice's page names two of its eight, and the Knight Council page names Kor Valar Ramparts, a dungeon the table credits to nobody. Where a dungeon boss is also a quest boss, as Mother's Judgement is in the Whispers from the Past story quest at Yshari Sanctum, the dungeon copies are the ones you can go back to. Which Codex aspect each of those dungeons pays is in the dungeons guide.
Once per character: the stronghold bosses
Fifteen bosses end the fifteen strongholds, and because a stronghold is cleared once and becomes a town, each of these fights happens once for each character you make. The locations guide has the levels and rewards; this table is about the fight.
| Boss | Stronghold | What the fight hinges on |
|---|---|---|
| Frosthorn, Ice Clan Champion | Malnok | Axe and frost pools after three Stormcallers |
| Negala, Lilith's Chosen | Nostrava | Kill Kozira and Torvala first, at level 25 or more |
| Nilcar, Forgotten Bishop | Kor Dragan | Blood attacks; three shielded incubators dictate where you stand |
| Fionnir, the Mad Druid | Moordaine Lodge | Three shapeshifting phases, ranged in the first |
| Tidewitch Ne'gana | Hope's Light | Two drowning assaults before her; attack from behind |
| Baelgemoth, Infernal Tormentor | Tur Dulra | Fire attacks after three tormented Druid spirits are freed |
| Captain Ezmin | The Onyx Watchtower | Goes intangible; area attacks and firebombs |
| Molqarth, the Hungerer | Temple of Rot | Two forms of poison and waves |
| Utulku, the Voice Below | Ruins of Qara-Yisu | Three Infernal Spires first, then red lightning |
| Rashta Reborn | Alcarnus | Necrotic Masses that cannot be hurt until she flees |
| Dark Cardinal Maldul | Altar of Ruin | Three Keystones to enter; Fallen keep spawning |
| High Priestess Hadar | Omath's Redoubt | Red-ring slam and summons after the investigation |
| Crusader Champions | Crusaders' Monument | Three ghostly knights at once |
| Duz'Agur, Eriman's Bane | Eriman's Pyre | Magic and fire AoE; blood pools in a straight line |
| Dianthus | Vyeresz | Poison ripples and blood pools from a serpent god |
Once, when the story says so
Twenty-one of our boss pages are story or quest fights, met at a fixed point and not again on that character. Reading them in act order is the closest thing our pages have to a campaign spine.
| Boss | Where in the story | Where on the map |
|---|---|---|
| X'fal, the Scarred Baron | Prologue, Darkness Within | Icehowl Ruins |
| Vhenard | Cost of Knowledge | Fractured Peaks; kill her Hell's Spawns to drop the shield |
| Tchort, Herald of Lilith | Fledgling Scholar | Horadric Vault, Fractured Peaks |
| Lilith's Lament | Act 1, Descent | Necropolis of the Firstborn; two phases and a Knights Penitent barrier |
| Airidah, Keeper of the Dead | Act 2 | Near the Wailing Hills; kill the Wraiths first |
| Amalgam of Rage Gestation | Act 2 | Shrouded Moors, Scosglen; 1,750 gold on our page |
| Astaroth | Act 2, Worlds Burns | Near Cerrigar; charges, fire breath, meteors |
| Genbar, the Shrine Keeper | Act 3, Whittling Sanity | Tusmaa Rift, Dry Steppes |
| Brol, the Tyrant King | Descent Into Flame | Charge and slam; minions |
| Elias | Act 3, Piercing the Veil, and again in Act 5, On the Precipice | Two fights, and a third as the Fallen Temple capstone boss |
| Eidolon of Orbei | Suffering Disquiet | Orbei Monastery; vortex, teleports, bone walls |
| Cyhrach, the First Born | Call of the Ancients side quest | Fractured Peaks; triple projectiles and homing orbs |
| Mohlon, Snake Queen | Act 5 | Serpent's Lair, Hawezar; level 38 on our page |
| Valtha, Witch of the Wastes | Act 5 | Meteors, fireballs, fire walls; drops the Purified Quicksilver |
| Duriel, Lord of Pain | Act 6 | Kehjistan; burrow, poison vomit, Freeze Aura |
| Karum, Hound of Hatred | Act 6, In Desolation's Wake | Paired with Ninsa in the same quest |
| Ninsa, Blight of Hatred | In Desolation's Wake | Two phases |
| Uznu, the Annihilator | Scouring of Caldeum | Fire breath and bombardment; attack from behind |
| Lilith | The final fight | Two phases, Creator of Sanctuary then Daughter of Hatred; drops the Mother's Embrace ring |
Two of the pages above double as dungeon bosses and are counted there: Mother's Judgement, and Elias, whose third appearance is the boss of the Fallen Temple. Lilith is the only story boss with a named unique drop on our pages, the Mother's Embrace ring, and Lilith's Lament is the only one with a guaranteed legendary.
The capstones: once per World Tier
Three fights sit outside every category above because they are gates. The High Council, four knights of whom the Sacred Physician dies first, and The Curator hold the Cathedral of Light at level 50, and beating the Curator is what unlocks World Tier 3 and, with it, unique items. Elias at the Fallen Temple does the same for World Tier 4 at 70. And the Echo of Hatred is the level 100 rematch with Lilith that pays the Blood Mount, the hardest single fight our pages describe. Our capstone guide notes that most players run each of the first two exactly once per character.
Frequently asked questions
How often do world bosses spawn in Diablo 4?
About every six hours, one boss in one of five arenas, per our world boss page, with roughly half an hour's notice on the map. Which of Ashava, Avarice or the Wandering Death appears, and where, is random.
Which boss appears in the most dungeons?
The Tomb Lord, at the end of 13 of the 115 dungeons in our master table. Scourge of the Land, Resurrected Malice and the Khazra Abomination follow with eight each.
Can a stronghold boss be fought again?
Not on the same character. Clearing a stronghold turns it into a town for that character, so the boss is gone until you make a new one. The Renown it paid, our hub notes, carries over anyway.
