Dissolution of Time is the Cauldron incantation that finally stops Chronos from coming back, and it is the key to the true ending.
Dissolution of Time is the single most important incantation in Hades 2, because it is the only thing that permanently ends the war with Chronos.
You brew it at the Cauldron in the Crossroads, and the wiki describes its effect as suppressing Chronos ability to reconstitute himself night after night. Without it, beating him just resets the loop.
The catch is the recipe. It costs seven Zodiac Sand and one Entropy, two rare reagents that force you to clear both the Underworld and the Surface routes before you can cast it.
This guide covers exactly what Dissolution of Time does, its full cost and requirements, how to farm the Zodiac Sand and Entropy it needs, and what casting it unlocks.
the Cauldron incantation that stops Chronos reconstituting himself.Dissolution of Time permanently suppresses Chronos's ability to reconstitute himself, which is what lets you actually win the war instead of resetting it every night, as of patch v1.0.
Throughout the campaign, beating Chronos only sends him back in time to try again, the same loop that returns Melinoe 
to the Crossroads after a death. The wiki states this incantation breaks that loop, removing his ability to come back night after night.
Casting it is the trigger for the true ending. It is the payoff of the entire main story, and the post-game content opens up once the incantation is complete. It is brewed at the same Cauldron 
as every other incantation, but it sits at the very top of the progression.
In short, this is the win condition. Every other system in the game eventually points toward gathering what Dissolution of Time costs.
Dissolution of Time costs seven Zodiac Sand and one Entropy, and it only becomes available after you have beaten Chronos at least once.
The unlock requirement is simple on paper: defeat Chronos once, then talk to Hecate about it. The hard part is affording it, since both reagents are gated behind repeated, difficult endgame fights on two different routes.
| Requirement | Detail |
|---|---|
| Unlock | Defeat Chronos once, then speak with Hecate to learn the incantation. |
| Zodiac Sand | 7 total, earned one at a time by defeating Chronos in Tartarus. |
| Entropy | 1, from a final Typhon kill after casting Disintegration of Monstrosity. |
| Where | Cast at the Cauldron in the Crossroads. |
Because Zodiac Sand comes from Chronos and Entropy comes from Typhon 
, you cannot brew Dissolution of Time by grinding a single route. You have to clear both the Underworld and the Surface.
The seven Zodiac Sand is the long grind, since you earn one per Chronos kill and have to win that fight seven times over.
Zodiac Sand drops one at a time for defeating Chronos, the Guardian of Tartarus, and it is repeatable. Seven kills is a meaningful ask given he is the hardest fight in the game, so in practice a stable, high-damage build matters more here than anywhere else. The wiki notes Zodiac Sand also feeds other incantations and Music Maker tracks, so do not spend it elsewhere until Dissolution of Time is done.
Entropy is a one-time gate with a setup. First cast the Disintegration of Monstrosity incantation, then beat Typhon one final time; Melinoe erases him with the Gigaros spear and a single Entropy spawns next to the Void Lens after the run. Our full true-ending walkthrough covers the run-by-run order, including the Zagreus 
conversations that grant Gigaros.
Do not spend Zodiac Sand on anything else until Dissolution of Time is cast. It is also used for incantations like Acceptance of Another Fate and for Music Maker tracks, and it is slow to farm, so a careless purchase can set your true-ending timeline back several Chronos runs.
Casting Dissolution of Time rolls the true ending and opens the door to the game's post-game content, including the secret epilogue.
With Chronos no longer able to reconstitute, the story reaches its real conclusion. From there you can pursue the hidden epilogue through the Three Fates 
sequence, chase remaining achievements, and keep playing the deeper Chaos 
and endgame challenges.
It also reframes the meta-progression. Once the main goal is done, the rest of the Night 
resistance content and the harder vows become the focus rather than the race to end Chronos.
Dissolution of Time is a Cauldron incantation that permanently suppresses Chronos's ability to reconstitute himself night after night. Casting it triggers the true ending, since it is the only way to actually win the war against Chronos rather than reset the loop.
It costs seven Zodiac Sand and one Entropy. Zodiac Sand is earned one at a time by defeating Chronos in Tartarus, and Entropy comes from a final Typhon kill after you have cast Disintegration of Monstrosity.
Defeat Chronos once, then talk to Hecate about it to learn the incantation. Unlocking it is easy; the real work is gathering the seven Zodiac Sand and one Entropy needed to actually cast it.
Zodiac Sand drops one at a time for defeating Chronos, the Guardian of Tartarus, and it is repeatable. You need seven, so you have to beat the hardest fight in the game seven times. Avoid spending Zodiac Sand on other incantations until this one is done.
Cast the Disintegration of Monstrosity incantation, then beat Typhon one final time. Melinoe erases him with the Gigaros spear, and a single Entropy spawns next to the Void Lens after the run summary. Pick it up before leaving.
Yes. Casting Dissolution of Time is the trigger for the true ending and opens the post-game, including the path to the secret epilogue. It is the payoff of the entire main story.
No. Zodiac Sand comes from Chronos on the Underworld route and Entropy comes from Typhon on the Surface route, so you must clear both paths to gather the full recipe.
It is the capstone of the main story, but not the last thing to do. After casting it you can chase the secret epilogue, remaining achievements, and harder endgame content like additional vows and Chaos trials.
