Cerberus is the House of Hades pet, corrupted by Chronos into the Infernal Beast you have to fight through fire.
Cerberus is the hardest fight in Hades 2 to feel good about winning, because the Infernal Beast you are battling is your own three-headed family dog.
He is the Hound of Hell, normally the beloved pet of the House of Hades, but Chronos cast him out and corrupted him into Infernal Cerberus, the Guardian of the Fields of Mourning on the Underworld route.
The fight is two phases of fire and corruption, with a reinforcement wave at half health that you have to clear before he reappears. Beat him and the corruption breaks; he runs off to find Hades in Tartarus.
This guide covers who Cerberus is, his two-phase fire kit, the add wave at 50%, the loadout that clears him, and the mistakes that get runs ended in the Fields.
Infernal Cerberus, a 21,500-health fire Guardian with a heavy add wave at 50% health.Cerberus is the Hound of Hell, the three-headed dog who guards the gates of the Underworld, and in Hades 2 he is the corrupted Guardian of the Fields of Mourning.
Normally he is the beloved pet of the House of Hades, a companion to Zagreus 
and Melinoe 
alike. The wiki notes that when Chronos 
conquered the Underworld, he cast Cerberus out and twisted him into Infernal Cerberus, the Infernal Beast that now blocks the way.
He is one of the Typhon 
bloodline, sharing the Father of All Monsters as a parent with Charybdis 
and the Lernaean Hydra. His keepsake is the Old Spiked Collar, and he is voiced by the real dogs Solo, Higgins, Regis, and Marzipan as of patch v1.0.
The emotional weight is the point. Once you defeat him, the corruption lifts and he runs off to be with Hades in Tartarus, which is why this Guardian fight reads as a rescue rather than a kill.
Infernal Cerberus has 21,500 health across two phases, and the gate between them is a reinforcement wave at 50% that you must fully clear before the fight continues.
His first phase is all fire from three heads. He pounds the ground for shockwaves, fires flaming maws that burst into rings of fire, sweeps a large semicircle of flame, and plants four timed circles that erupt into flaming heads when their timers expire. The wiki specifies that at 50% health he burrows underground and summons a group of adds.
| Element | What it does |
|---|---|
| Paw Slam | A heavy paw strike that sends a mini shockwave outward. |
| Flaming Maws | Each head spits a fireball that explodes into a ring of fire at the edge of its range. |
| Fire Swipe | A swipe that launches a large semicircle of fire across the arena. |
| Erupting Circles | Four marked circles appear, one under him and three around him, then flaming heads burst up when the timers expire. |
| Reinforcements (50%) | He burrows and summons a group of Elites: Mourners, Blight-Shades with Sorrow-Spillers, Lamia, or Holeheart. Phase two begins once they are all dead. |
If you raise the Vow of Rivals to Tier 3 or above, the arena gains lava traps and he gains magma armor, a guard stance that counters your hits with fireballs, and a third-phase barrier that absorbs 23 hits. Rapid-hit weapons and Scorch chew through that barrier quickly.
Treat the 50% reinforcement wave as the real test, bring fire resistance for the persistent flames, and keep moving through his fire patterns.
The wave is the gate. The wiki states phase two only starts once Cerberus reappears after every reinforcement is dead, so the faster you clear the Elites he summons, the less time you spend dodging his fire alone. Area damage that hits the whole add pack at once is far better here than single-target, which is the opposite of a fight like Charybdis.
The fire patterns are readable once you know the tells. His flaming maws explode at the edge of their range, so staying at mid distance keeps you between him and the blast rings. The four erupting circles telegraph clearly before the heads burst up, so simply step off the marked ground. A Hecate 
dash boon or any fire resistance smooths out the chip damage from his lingering flames.
Bring add-clear into the Fields of Mourning. A wide Cast or a chain effect deletes the 50% reinforcement wave in one go, which is the single biggest time save in the fight. After a few runs, the rest of his kit is pure pattern recognition.
Area damage clears his add wave, and fire resistance keeps you alive through a kit that is almost entirely flame, so prioritize both over raw single-target burst.
Wide Cast boons or chain effects handle the 50% reinforcements cleanly, which is the part of the fight that punishes weak add-clear. For the body, any steady damage works given his moderate 21,500 health. If you are running the Vow of Rivals, rapid-hit weapons or Scorch are specifically called out by the wiki for breaking his 23-hit barrier.
For keepsakes, the Knuckle Bones from Odysseus again trims this Guardian HP and incoming damage, and any defensive keepsake helps against the magma armor counters under Rivals. A Scylla 
run earlier on the route means you have likely seen the Underworld Guardians by now, so carry whatever cleared Oceanus into the Fields.
Fire resistance is underrated here. Almost every Cerberus attack leaves burning ground, and the chip from standing in it adds up across a long fight. A boon or Arcana that cuts fire or area damage turns the persistent flames from a slow drain into a non-issue.
Cerberus is the three-headed Hound of Hell and the beloved pet of the House of Hades. In Hades 2, Chronos cast him out of the Underworld and corrupted him into Infernal Cerberus, the Guardian of the Fields of Mourning on the Underworld route.
Clear the reinforcement wave at 50% health quickly with area damage, since phase two only starts once every add is dead. Bring fire resistance for his persistent flames, stay at mid distance to avoid the flaming maw rings, and step off the marked erupting circles.
Infernal Cerberus has 21,500 health in a normal run, rising to 31,500 in the Unrivaled version. The fight has two phases split by a reinforcement wave at the 50% health threshold.
At half health Cerberus burrows underground and summons a group of Elite enemies, which can be Mourners, Blight-Shades with Sorrow-Spillers, Lamia, or Holeheart. Phase two only begins once you have killed all of them, so fast add-clear is key.
Defeating Infernal Cerberus grants 1 Tears, which is repeatable on later clears. Story-wise the corruption lifts once he is beaten, and he runs off to rejoin Hades in Tartarus, so the fight functions as a rescue.
Yes. Cerberus is a child of Typhon, the Father of All Monsters, which makes him kin to Charybdis and the Lernaean Hydra. His keepsake is the Old Spiked Collar, and he is voiced by the real dogs Solo, Higgins, Regis, and Marzipan.
At Tier 3 or above the arena gains lava traps and Cerberus gains magma armor, a guard stance that counters your hits with fireballs, and a third-phase barrier that absorbs 23 hits. Rapid-hit weapons and Scorch break that barrier fastest.
Cerberus is the Guardian of the Fields of Mourning, the third region of the Underworld route after Erebus and Oceanus. Beating him opens the path toward Tartarus and the final boss, Chronos.
