Almost every Duo Boon ranking you will find sorts the same ten boons and calls it a list. Two things are wrong with that, and the second one matters more than the first.
The count is wrong. Guides state that Hades II contains 56 Duo Boons. The current game data holds 37. That is not a scrape artefact — it is arithmetic you can check. Nine gods can form Duos. Zeus and Hera each appear in 9, because of the Queen’s Ransom / King’s Ransom pair; the other seven appear in 8 each. That is 7 × 8 + 2 × 9 = 74 god-slots, and every Duo occupies two, so 74 ÷ 2 = 37. Fifty-six is seven gods multiplied by eight partners — a slot count for part of the roster, not a boon count.
The comparison method is wrong. Duo Boons do not carry the four-tier Common / Rare / Epic / Heroic line that 144 ordinary boons have. The data gives each Duo one flat number. So the usual tier-list logic — “same boon, higher rarity, better” — has nothing to grip. What separates Duos is how hard they hit and how often, and for the four with a stated interval you can divide one by the other.
The four you can actually compute per second
Most Duo values are single events, so a per-second rate does not exist. Four of them state a tick interval, which makes them directly comparable:
| Duo | Gods | Per tick | Interval | ≈ per second |
|---|---|---|---|---|
| Glorious Disaster | Apollo + Zeus | 20 bolt | 0.13 sec | 154 |
| Tropical Cyclone | Apollo + Demeter | 70 gale | 0.6 sec | 117 |
| Scalding Vapor | Hestia + Poseidon | 20 steam | 0.2 sec | 100 |
| Hail Storm | Demeter + Zeus | 30 lightning | 0.5 sec | 60 |
Glorious Disaster out-rates the Duo that Dot Esports puts at number one by roughly 54 percent. That does not make their ranking wrong — it makes it a ranking of something else, because these four are gated very differently:
- Glorious Disaster costs +30 Magick to channel and only fires inside your Ω Cast. You are paying a resource cost for the whole duration, which is why Apollo + Zeus wants Hermes and any Magick regeneration it can find.
- Tropical Cyclone only fires while you stand in a Gust, which means it fires while you are doing the thing Cast builds are worst at: staying still.
- Scalding Vapor needs a foe carrying Froth to be hit by Hestia’s fire. Two conditions, from two different gods, and one of them is a status you have to apply first.
- Hail Storm needs Freeze on the target and then keeps striking it. It is the only one of the four that is free to run once the condition is met.
That table is the whole argument of this page: a Duo’s headline number tells you almost nothing until you read the condition attached to it. Scalding Vapor is the best Duo in the game when its condition is already met, and it is dead weight when it is not.
Queen’s Ransom and King’s Ransom destroy each other
These two are the only Duos in the game that cost you something to take, and they are a single decision wearing two names.
| Duo | Gods | What it does |
|---|---|---|
| Queen’s Ransom | Hera + Zeus | Sacrifice every Zeus boon; each one raises the level of all your Hera boons by +4 |
| King’s Ransom | Hera + Zeus | Sacrifice every Hera boon; each one raises the level of all your Zeus boons by +4 |
The wiki entry for King’s Ransom states plainly that taking it destroys Queen’s Ransom. So there is no build where you hold both, and the Hera + Zeus pairing is not “two Duos” in any practical sense — it is one fork in the road.
Read what the fork actually asks. Queen’s Ransom converts a wide Zeus spread into a tall Hera spread. If you are running Hera as your main damage god and picked up three Zeus boons incidentally, Queen’s Ransom turns those three into +12 levels across your Hera boons. That is the single largest level injection available from any Duo. If your Hera boons are the ones you care about, this is not a sacrifice at all — it is a conversion of dead weight.
The failure mode is taking it in the wrong order. Take Queen’s Ransom after you have already stacked Zeus as your primary and you have just deleted your own build.
The three that require one exact boon
Every Duo needs “one of each” from its two parent gods. Usually each side accepts a handful of options, so you have room to manoeuvre. Three do not:
| Duo | Gods | The side that accepts only one boon |
|---|---|---|
| Sunny Disposition | Aphrodite + Apollo | Aphrodite: Heart Breaker only |
| Glorious Disaster | Apollo + Zeus | Apollo: Prominence Flare only |
| Master Conductor | Hephaestus + Zeus | Zeus: Static Shock only |
These are not harder to find; they are harder to set up, because a single wrong pick on one side closes the Duo permanently for that run. If you want Glorious Disaster, you must take Prominence Flare from Apollo — not Nova Strike, not Solar Ring. Every guide that recommends Glorious Disaster as a top pick without mentioning Prominence Flare is describing a boon you will probably never see.
Three Duos have the opposite problem: a prerequisite list so wide that it reads as easy but is not.
The four with a third layer
| Duo | Gods | Layers | Why the third layer hurts |
|---|---|---|---|
| Beach Ball | Apollo + Poseidon | 3 | Needs Breaker Rush or Blinding Rush plus a boon from each god’s pool |
| Natural Selection | Demeter + Poseidon | 3 | Cross-pool: Buried Treasure, Sea Star, Steady Growth or Plentiful Forage plus both pools |
| Heinous Affront | Ares + Zeus | 3 | Cross-pool including Visceral Impact, Light Smite or Divine Vengeance |
| Ripple Effect | Hera + Poseidon | 3 | Needs Fine Line or Ocean Swell plus both pools |
A third layer is worse than it sounds, because the cross-pool boons are themselves conditional. Beach Ball accepts six Poseidon options and four Apollo options on top of the Rush requirement, which sounds generous until you notice that the Rush boons are the same boons most builds skip.
Every Duo Boon, all 37
Grouped by god pair. “Pool” is the number of boons that can satisfy the prerequisites, multiplied across both gods — a low pool means you must choose precisely, not that the Duo is weak.
| Duo | Gods | Effect | Value | Pool |
|---|---|---|---|---|
| Sunny Disposition | Aphrodite + Apollo | Creating Heartthrobs creates more of them | +2 Heartthrobs | 4 |
| Carnal Pleasure | Aphrodite + Ares | Collecting Plasma creates a Heartthrob | 25% chance | 12 |
| Hearty Appetite | Aphrodite + Demeter | Weapon damage scales with Max Life | +10% per 100 Life | 16 |
| Love Handles | Aphrodite + Hephaestus | Hephaestus blasts also create a Heartthrob | 120 area damage | 8 |
| Ecstatic Obsession | Aphrodite + Hera | Auto-Charm one foe while others remain | 2+ foes | 6 |
| Burning Desire | Aphrodite + Hestia | Scorch on Weak foes never diminishes | Scorch lasts ∞ | 4 |

| Romantic Spark | Aphrodite + Zeus | Rushing into foes triggers Blitz immediately | +80% Blitz damage | 8 |
| Cutting Edge | Apollo + Ares | Ares blades drop one extra time, wider area | +50% area | 8 |
| Tropical Cyclone | Apollo + Demeter | Fire gales while standing in a Gust | 70 every 0.6 sec | 8 |
| Rude Awakening | Apollo + Hephaestus | Hephaestus blasts clear Daze and hit harder for it | +300 blast | 6 |
| Sun Worshiper | Apollo + Hera | First foe slain each Encounter fights for you | +200% servant damage | 4 |
| Warm Breeze | Apollo + Hestia | Dodge, or a Daze miss, restores Life | 10 Life | 12 |

| Glorious Disaster | Apollo + Zeus | Channel Magick into Ω Cast for repeated lightning | 20 every 0.13 sec | 3 |
| Hostile Environment | Ares + Demeter | Ω Cast is stronger and follows you | +100% Ω Cast | 8 |
| Coffin Nail | Ares + Hephaestus | Ares blades fall immediately, hit harder | +25 blade damage | 10 |
| Universal Donor | Ares + Hera | Keep some Plasma bonuses when leaving a Location | 20 retained | 12 |
| Fourth Degree | Ares + Hestia | Hestia fireballs inflict stronger Wounds | +250 Power | 8 |
| Arterial Spray | Ares + Poseidon | Splash may hit twice | 25% chance | 8 |
| Heinous Affront | Ares + Zeus | Inflicting Wounds can also trigger your on-damage effects | 6 sec recharge per foe | 24 (3 layers) |
| Cryo Pounder | Demeter + Hephaestus | Hephaestus blasts hit Frozen foes harder | +50% blast | 4 |
| Cherished Heirloom | Demeter + Hera | Keepsakes are stronger for the night | +1 rank | 16 |
| Freezer Burn | Demeter + Hestia | Freezing a Scorched foe deals damage and clears Scorch | 200% of Scorch | 4 |
| Natural Selection | Demeter + Poseidon | Leftmost-column boons gain levels, spread across them | +8 total Lv. | 48 (3 layers) |
| Hail Storm | Demeter + Zeus | Freeze effects call repeated lightning | 30 every 0.5 sec | 8 |
| Brave Face | Hephaestus + Hera | Spend Magick to resist up to 30% of damage | 10 Magick per point | 24 |
| Chain Reaction | Hephaestus + Hestia | Blasts used just after recharging fire twice | 1 sec window | 8 |
| Seismic Servo | Hephaestus + Poseidon | Recharging boon effects recharge faster | +35% speed | 8 |
| Master Conductor | Hephaestus + Zeus | Chain lightning bounces off you, gaining damage | +15% per bounce | 4 |

| Ripple Effect | Hera + Poseidon | Fine Line and Ocean Swell may fire twice | +35% chance | 18 (3 layers) |
| Queen’s Ransom | Hera + Zeus | Sacrifice Zeus boons for Hera levels | +4 Lv. each | 8 |
| King’s Ransom | Hera + Zeus | Sacrifice Hera boons for Zeus levels | +4 Lv. each | 8 |
| Scalding Vapor | Hestia + Poseidon | Froth plus Hestia fire engulfs foes in Steam | 20 every 0.2 sec | 10 |
| Thermal Dynamics | Hestia + Zeus | Blitz also inflicts Scorch | 160 Scorch | 4 |
| Killer Current | Poseidon + Zeus | Lightning hits Froth-afflicted foes harder | +30% | 10 |
That is 37 rows, 36 distinct god combinations, and the two Ransoms account for the only duplicated pair.
The standouts that are not about damage
Four Duos in that table do not add damage at all, and they are the ones that change whether a run survives:
- Brave Face (Hephaestus + Hera) converts Magick into damage resistance at 10 Magick per point, resisting up to 30 percent of any hit. It is the only Duo that answers “I keep dying to chip damage”.
- Island Getaway (Aphrodite + Poseidon) gives +15% resistance and, more importantly, makes Aphrodite’s boons treat every foe as nearby. That single clause fixes Aphrodite’s core weakness on ranged weapons.
- Cherished Heirloom (Demeter + Hera) adds +1 rank to every Keepsake for the night. If you are running a Keepsake-dependent opening, this is a whole extra tier on all of it.
- Universal Donor (Ares + Hera) keeps 20 of your Plasma bonuses when you leave a Location. Plasma resets between regions by default; this is the only way to carry it.
How to actually chase one
Duos are not random drops — they are a setup problem, and the setup is repeatable:
- Pick the Duo before the run, not during it. Read its prerequisite line now, while nothing is at stake.
- Take the narrow side first. For Glorious Disaster that means taking Prominence Flare the moment Apollo offers it, because everything else Apollo offers is a dead end for that Duo.
- Use Keepsakes to force the gods, not to force the Duo. Keepsakes guarantee a god appears; they do not guarantee the Duo rolls. Two gods’ Keepsakes early is the standard play.
- Check the third layer before committing. If your target is Beach Ball, verify you have a Rush boon, or you are collecting prerequisites for nothing.
- Never take the second Ransom by accident. If you hold Queen’s Ransom, King’s Ransom is not an upgrade — it is a delete button for your Hera boons.
