Hades 2 has two difficulty systems pointing in opposite directions, and they are both in the same menu area, which makes them easy to confuse.
God Mode lowers the difficulty and raises itself when you fail.
The Oath of the Unseen raises the difficulty and pays you for it.
Neither locks anything. Both are worth understanding before you decide you are “playing it wrong”.
God Mode: a slider disguised as an assist
| Property | Value |
|---|---|
| Starting resistance | 20% |
| Gain per failed run | +2% |
| Cap | 80% |
| Where | Options → Gameplay → God Mode |
| When | Any time, including mid-run |
| Cost | None |
The buff it applies is called Deus Ex Machina — a joke about the ancient theatrical device, and a fair description.
The counterintuitive part, and the reason it is not simply “easy mode”:
Winning does not increase your resistance. Only runs that end in Melinoë retreating to the Crossroads add the 2%.
So God Mode is not a difficulty setting you choose. It is a self-correcting mechanism for players who keep losing — it gives you nothing while you are winning, and it escalates while you are not. A player who clears consistently will sit at 20% forever; a player who is stuck will climb toward 80% without having to decide anything.
The slider matters more than the number. You can set the maximum anywhere from 20% to 80% in the Options menu. That means you can decide in advance how much help the mode is allowed to give, which is a meaningfully different design from a fixed assist.
Nothing is locked. No achievements, no endings, no content. The only difference is that God Mode run records are stored separately, so assisted clear times do not appear alongside unassisted ones. That is a leaderboard distinction, not a penalty.
And turning it off costs nothing: you keep every percent you accumulated, and turning it back on restores the full stored amount.
Why this matters more here than in most games
Because, as the length of the game shows, Hades 2’s story is dialogue-gated rather than skill-gated. Losing advances the plot. Which means difficulty and progress are largely orthogonal — a player using God Mode is not skipping content, they are skipping the part where they repeat the same wall.
If you are stuck at the first clear, the honest advice is: turn it on, get your clear, learn the bosses with the pressure off, and turn it off when you want the challenge back. The game is designed to allow exactly that.
The Oath of the Unseen: the other direction
Unlocked after you defeat Chronos at least once, via a pillar in the Crossroads training ground, between the entrances to the Underworld and the Surface.
It runs Testaments of Night:
- Pick a Guardian from the offered cards.
- Equip the required weapon — the Testament specifies it.
- Toggle Vows until your Fear reaches the card’s required level.
- Clear the boss and earn Nightmare, the resource used mainly for upgrading weapon aspects.
You do not need every Vow. You need enough to hit the threshold — which is, in practice, the actual puzzle of the system.
Sixteen Vows, each upgradeable to Rank 3. Each rank adds one Fear, so a single Rank 3 Vow equals three Rank 1 Vows in cost but concentrates the difficulty in one place.
| Vow | Effect at Rank 1 / 2 / 3 |
|---|---|
| Pain (also listed as Blood) | Foes deal +20% / +60% / +100% damage |
| Grit | Foes have +10% / +20% / +30% Health |
| Wards | Foes have 1 / 2 Barrier |
| Frenzy | Foes are +20% / +40% faster |
| Hordes | Encounters have +20% / +40% / +60% more foes |
| Menace | 10% / 25% chance foes come from the next region |
| Return | +25% / +50% chance slain foes return as Revenants |
| Fangs | Armoured foes gain 1 / 2 random Perks |
| Scars | Health effects are 75% / 50% / 0% effective |
| Debt | Gold costs +40% / +80% |
| Shadow | Warden encounters always contain at least 1 Shadow Servant |
The Vows that are not just “more damage”
Most of that table is arithmetic. Three are not, and they are the ones that change how you play:
Vow of Scars at Rank 3 makes all health effects 0% effective. Every heal, every lifesteal, every regeneration boon — dead. That is not a damage increase, it is a build restriction, and it invalidates whole archetypes rather than making them harder.
Vow of Fangs gives armoured enemies random Perks. Armoured enemies already do not stagger, so this stacks a second layer of unpredictability onto the enemies you were already avoiding.
Vow of Return turns corpses into Revenants. In a game where the standard tactic is to focus one enemy down and reduce the number of attackers, this makes every kill a potential new threat. It punishes exactly the habit every guide recommends.
The escalating part nobody warns you about
Every time you complete a Testament or run, the Fear requirements on the other Testaments increase.
So the Oath is not a fixed ladder you climb once. It ratchets. The first Testament you take is the cheapest you will ever be offered, and by the time you have cleared a dozen, the same Guardian costs more Fear for the same Nightmare.
That is the actual long-term structure of Hades 2’s endgame: not a difficulty curve you learn, but a floor that rises underneath you.
Which one to use, and when
- Stuck on the first clear: God Mode on. Get the clear, learn the routes, then decide.
- Chasing Nightmare for aspect upgrades: Oath of the Unseen. That is the only source.
- Want the difficulty you remember from Hades 1: take Vows rather than refusing God Mode. Vows are tuned; the base game is the base game.
- Both at once: technically possible and they pull against each other. In practice, most players use God Mode to reach the endgame, turn it off, and then take Vows.
The short version
- God Mode: 20% → +2% per loss → 80% cap, slider-adjustable, toggleable any time, nothing locked.
- Winning gives it nothing. It exists to catch players who lose.
- The Oath of the Unseen unlocks after one Chronos kill and is the only route to Nightmare.
- 16 Vows, three ranks each, one Fear per rank, and the Fear floor rises as you complete Testaments.
- Scars, Fangs and Return are the three that change how you play rather than how hard it hits.
