Chronos is the end of the underworld route, and he is two fights wearing one health bar.
Phase one is a positioning test. Every attack he has can be outranged, and the correct answer to most of them is to be somewhere else.
Phase two is a reaction test. He teleports you to a clock face and starts killing you outright if you are one tile away from where you need to be, inside a two-second window.
Players who clear phase one comfortably and die on the clock are not bad at the game. They are being asked for a skill the first phase never tested.
Phase one: outrange everything
Chronos’s moves in the throne room, and the honest answer to each:
| Attack | Tell | Answer |
|---|---|---|
| Forward dash | He dashes at you | Dodge through him, not away. Running away puts you in the explosive trail |
| Scythe slash | Right arm pulls back in a charging motion | Range is longer than it looks, and it leaves delayed explosions along its path. Dodge behind him and punish |
| Spinning scythe | A drawn-out grunt as he lifts the scythe to his left | Boomerang arc from his left to his right. Almost undodgeable at melee range — be outside it |
| Cyclone + projectile | Cyclone pulls you in, then a large projectile | Sprint out of the cyclone; the projectile then usually misses. Dodging behind him at the start is a free punish window |
| Golden orb shield | Orbs circling him | Wait it out — or bait him into dashing into a wall, and the orbs shatter against it |
| Minion spawn | Six weak or two stronger enemies | Clear quickly, but not at the cost of position |
| Orbs everywhere | He teleports and fills the room | Predictable: usually at about 25% and 75% HP, or right after a minion summon |
| Hourglass banners | Four banners with blue ground rings | Anything standing in a ring gets a shield. Destroy the banners, not the minions |
The single biggest mistake in phase one is fighting the adds. The banners are the actual threat — they make everything else unkillable — and the minions are a distraction designed to waste your damage. Pour everything into Chronos or the banners and let the adds follow you around.
At 50% health his attacks speed up and start chaining up to three at once. That is the phase-one difficulty spike, and it is where a slow weapon starts to feel bad — not because of damage, but because you no longer get a full punish window between moves.
Phase two: the clock
His first bar empties, he heals, and you are on a giant golden clock face. He keeps everything from phase one and adds three time abilities.
The instant kills are the whole phase.
- Red screen: everything goes red except one glowing Roman numeral. Dash onto it. You have roughly two seconds. If you are not standing there, you take lethal damage.
- Dark screen: the safe zone is a ring near the centre of the arena — and the floor inside the ring is also lethal. It is a donut, not a circle.
That distinction kills people who correctly identify the ring and then stand in the middle of it.
Expanding golden rings are walls, not waves. Dodge through them, and time it so your invincibility frames are active as the ring reaches you — panicking early means your i-frames expire while you are still inside the hitbox.
Hourglass minions are a genuine dilemma: ignore them and they throw blasts at you; kill them and they leave slowing fields on the floor. The answer is collateral damage — hit them while you are already hitting Chronos, and never chase one across the arena.
The HP lock nobody mentions
His scythe tip does more than damage: it locks your maximum HP, shown as grey hearts that do not come back during the fight.
This inverts normal prioritisation. The obvious, dramatic attacks — the screen wipes, the orb storms — are survivable if you are in the right place. The quiet scythe tip permanently shrinks your margin, and by the last third of phase two a single mistake kills you because you never had the health to spare.
The loadout
A lingering Cast is worth more than a burst boon. Chronos stands still during his casting animations, so a Cast dropped on him chips away steadily while you spend your attention on dodging. Players report 10-15% of his health coming from smart Cast placement alone.
The Binding Circle is the specific answer to his dashes. A cast that can be placed away from your position — Hestia and Zeus both offer this — keeps the circle between you and him, which stops the charge attacks that otherwise close the distance you are trying to protect.
Knuckle Bones (Odysseus’s keepsake) reduces his starting HP and his damage, and it works on Chronos. If you are stuck, this is the single highest-value swap.
Do not bring the Moonstone Axe expecting to block your way through. Its block handles most of his attacks but not the phase-two screen wipe. That one is a movement check regardless of your weapon.
Why the range plan works, and where it stops
Staying at maximum range trivialises nearly all of phase one: the dash, the slash, the boomerang and the cyclone all fail at distance except the projectile. That is the correct default.
It stops working in phase two, because the clock face is small and the safe zones are positional rather than distant. So the plan is:
- Phase one: maximum range, punish only the two windows (behind him after the slash, behind him at the cyclone’s start).
- Phase two: stay mobile, keep the Cast down, and treat every screen change as an emergency. Damage is secondary to being in the right tile.
Before you get there
The underworld route to Chronos runs Hecate, Scylla, Cerberus, then the Titan. Beating him once drops a Zodiac Sand, which is one of the three ingredients for the incantation that ends Typhon — so the two final bosses are a loop, and neither can be finished permanently without the other.
