Hades II Bosses and Progression Guide

Hades II has eight main route Guardians in v1.0: four in the Underworld and four on the Surface. This order excludes optional minibosses and the stronger Vow of Rivals variants. The two routes are parallel once the upper path is unlocked, so clearing one route does not make the other disappear.

Underworld route

1. Headmistress Hecate — Erebus.
2. Scylla and the Sirens — Oceanus.
3. Infernal Cerberus — Fields of Mourning.
4. Chronos, Titan of Time — Tartarus.

Surface route

1. Polyphemus — City of Ephyra.
2. Eris, Strife Incarnate — Rift of Thessaly.
3. Prometheus, Titan of Foresight — Mount Olympus.
4. Typhon, Father of All Monsters — Summit.

The route and boss order above follows the complete v1.0 boss list. A skull-marked chamber can hold a Warden or miniboss, but those encounters are not additional route-ending Guardians.

The Surface opens through Permeation of Witching-Wards, then becomes survivable through Unraveling a Fateful Bond. Hecate reveals the first incantation after Melinoë has reached the Fields of Mourning, met Hermes in Erebus, and learned about the war above. Moros teaches the second after an initial Surface attempt.

• Permeation of Witching-Wards costs 3 Moly, 1 Cinder, and 1 Shadow. Shadow is brewed from 30 Ash, 30 Psyche, and 3 Fated Fabric, then takes 12 encounters to finish.
• Unraveling a Fateful Bond costs 2 Lotus, 2 Moss, 2 Nightshade, and 2 Thalamus. It removes the escalating Chthonic Fate damage that cuts short early Surface runs.

If the upper gate is still sealed, follow the full Surface ward sequence rather than farming ingredients blindly. The first gate and the survival curse are separate progression checks.

The Underworld route is the first available path and the clearest place to learn a stable build. These are practical priorities, not a demand for one specific weapon or boon package.

• Hecate: respect the expanding rings, attack only when you can still leave space, and use your Cast to keep summoned enemies from crowding the arena. When the clones appear, do not burn Magick into every target; identify the one taking damage and keep enough mobility for the homing polymorph curse.
• Scylla and the Sirens: reduce the number of active attackers instead of splitting damage evenly. Area damage around the stationary drummer can also catch Scylla when she closes in. Keep moving through the guitarist’s lanes and floor hazards, then save burst damage for the final Scylla sequence.
• Infernal Cerberus: the attacks are slow but punishing. Leave red ground circles immediately, avoid standing in front of the claws and blasts, and take the long recovery after a slam as your damage window. A short safe combo is better than trading into one enormous hit.
• Chronos: plan for two phases. Clear banners and summoned enemies before the arena becomes unreadable, move out of time-stop circles, and treat the bright safe area in the second phase as mandatory when the rest of the clock face darkens. Stop attacking and reposition early; the darkened area can be lethal.

A run that reaches Chronos with a coherent damage plan and one defensive layer is usually healthier than a higher-damage run built from unrelated boons. The final Underworld fight rewards a simple loop you can repeat under pressure.

The Surface route asks for more mobility and cleaner resource management. It also carries route-specific materials, so even a run that does not reach Typhon can still unlock meaningful Crossroads progress.

• Polyphemus: ranged damage is safest because his stomps, leaps, and grab punish close-range greed. Lure him away from sheep when possible; eating one restores his health. If you play melee, wait for the end of a long slam or leap before committing.
• Eris: use the arena pillars against her gunfire, but move when the purple snipe line appears because that shot can destroy cover. Avoid burning oil and give her extra space after she fires the self-buffing shot that raises her damage.
• Prometheus: keep enough health and attention for the fire-lane memory check. When he leaves the stage and lanes turn red, memorize the safe order and move through it instead of trying to squeeze in damage. Save one reliable mobility or defensive option for this sequence.
• Typhon: stay patient near the upper part of the arena, read the large windups, and dodge away from the chin slam and across the sweeping laser. Destroy eggs before they hatch into armored enemies, then return to controlled damage while Olympus helps advance the fight.

Typhon is the final Surface Guardian. Prometheus may still feel like the sharper execution test for some builds, so do not read one difficult matchup as proof that the entire route is underpowered.

Start by pushing the Underworld far enough to unlock the Surface, then alternate routes according to the materials and story steps you need. There is no universal rule that every save must defeat Chronos before investing in the upper path. The game is designed around progress in both directions.

Choose the Underworld when you are still learning your weapon, need its route rewards, or want the longer-established path toward Chronos. Choose the Surface when a Cauldron recipe, weapon upgrade, relationship, or story beat asks for materials found above.

Supergiant said the Warsong Update completed the core structure of both routes. Treating one as optional side content leaves progression resources and half of the boss sequence unused.

When a Guardian wins several times in the same way, improve one permanent layer at a time. Spreading every resource across every system makes it harder to feel which upgrade actually solved the problem.

1. Arcana and Grasp: raise the amount of active support before chasing expensive sidegrades. The Arcana and Grasp guide explains the system without locking you into one deck.
2. One weapon plan: improve and practice one Nocturnal Arm or Aspect long enough to learn its safe damage loop. The beginner weapons and first-runs guide is the better starting point if every option still feels unfamiliar.
3. Keepsake and Familiar: choose support that fixes the current route problem instead of the rarest-looking item. Use the keepsakes and relationship unlocks guide when a gift or character reward is still missing.
4. Cauldron incantations: prioritize recipes that unlock a route, gathering option, or lasting utility before cosmetic conveniences.
5. Route materials: enter a run with one resource target. A failed boss attempt can still be productive if it completes an upgrade waiting at the Crossroads.
6. Build focus: make the Attack, Special, Cast, and Magick economy support the same plan. A smaller set of compatible boons is easier to execute than a collection of unrelated effects.

A failed run only becomes useful when you identify the failure that happened before the final hit. Use the pattern of the loss to choose the next upgrade or practice goal instead of changing the entire build at random.

• You arrive with very little Life: the route is the problem before the Guardian is. Take safer chamber choices, protect Death Defiance, and stop buying damage that never helps you reach the arena in usable condition.
• You survive for a long time but cannot finish: the build lacks focused damage. Strengthen the Attack, Special, or Cast you actually use and stop dividing Poms and hammers across moves that do not share the same combat loop.
• One attack ends every attempt: treat the next run as pattern practice. Reach that move with enough Life to watch its tell, stop attacking when it begins, and learn the safe position before trying to shorten the fight.
• Adds and projectiles make the arena unreadable: prioritize crowd control and clear the dangerous summons before returning to the Guardian. Damage on the boss is not progress if the screen becomes impossible to manage ten seconds later.
• The build works below but collapses above: the Surface may be exposing weak range, mobility, or resource economy. Change the keepsake or one defensive tool first; a route-specific weakness does not require rebuilding every permanent system.

Write down the specific failure in one sentence: low Life on arrival, low damage, missed tell, arena clutter, or route mismatch. The next run then has one measurable job, which is much more useful than demanding an immediate clear.

A first route clear is a milestone, not the end of Hades II. Version 1.0 added the true ending, new Fated List prophecies, many character events, and late-game unlockables. Keep talking to characters, checking the Cauldron, and running both routes after the first victory; the game does not deliver its full resolution in one successful night.

“A sweeping story that continually unfolds through your every setback and accomplishment.” — Supergiant Games

That line comes from Supergiant’s v1.0 launch description. It is also the safest way to read a run that ends at a familiar Guardian: dialogue, recipes, prophecies, relationships, and permanent upgrades can still advance.

Vow of Rivals is optional late-game difficulty, not a requirement for the first clear or the basic boss order. It changes Guardians into stronger variants with additional surprises. Learn the normal encounter first; adding the vow while the base pattern still feels chaotic makes it harder to diagnose whether the problem is execution or difficulty scaling.

The feature arrived in the official Unseen Update alongside Hidden Aspects and Godsent Hexes. Use it after the regular route feels stable and you want a deliberate Guardian challenge, not as a shortcut to ordinary progression.

A missing conversation or incantation can look like a combat wall. Run this checklist before spending another night repeating exactly the same route and build.

1. Talk to everyone at the Crossroads after each return, including characters without an obvious quest marker.
2. Check the Cauldron for new incantations and alchemy recipes before starting another run.
3. Try the other route when the next recipe or relationship needs a Surface or Underworld material.
4. Carry the right gathering tool or Familiar for the resource you are actually trying to collect.
5. Simplify the build to one weapon loop, one main damage source, and one defensive answer.
6. Name the attack that ends the run and spend the next attempt learning that tell instead of racing the health bar.
7. Keep playing after a clear because the true ending and late-game systems require continued progress rather than one victory.

The useful question is not “Why am I still losing?” It is “Which permanent unlock, route resource, or boss tell is the next smallest problem?” Solving that one item makes the following run more informative even when it is not yet a win.
