Each of the six Nocturnal Arms has a secret fourth aspect, and unlocking it takes a specific ritual at the Silver Pool.
Every weapon in Hades 2 has a fourth aspect the game never tells you exists, and finding them is one of the best-kept secrets in the build.
These hidden aspects sit behind the three visible ones on each Nocturnal Arm, and they are named after underworld deities from outside Greek myth: Anubis, Nergal, Hel, Shiva, the Morrigan, and Supay.
Unlocking one is a ritual, not a purchase. You rank a specific aspect to level five, coax a waking-phrase out of the right god, then activate the Silver Pool in the Crossroads to reveal the secret aspect for sale.
This guide lists all six hidden aspects and what they do, then walks through the exact unlock steps that are the same for every weapon.
six hidden aspects, one secret fourth aspect per Nocturnal Arm.Every hidden aspect uses the same three-step ritual: rank up one of the weapon visible aspects to level five, get a waking-phrase from the matching god, then activate the Silver Pool in the Crossroads.
The wiki lays out the exact sequence, and the Witch's Staff 
is the clearest example. First you raise its Aspect of Circe or Aspect of Momus to level five. Then you talk to Circe 
with any weapon equipped until she gives the waking-phrase. Finally you activate the Silver Pool in the Training Grounds, which reveals the hidden Aspect of Anubis for purchase.
| Step | What to do |
|---|---|
| 1. Rank to five | Bring one of the weapon two non-Melinoe aspects to level five with Titan Blood. |
| 2. Waking-phrase | Talk to that aspect god, with any weapon equipped, until they speak a specific cryptic line. |
| 3. Silver Pool | Activate the Silver Pool in the Crossroads to reveal the hidden aspect. |
| 4. Purchase | Buy the revealed aspect with Tears plus the weapon reagent, like any other aspect. |
The pattern repeats for all six weapons. The only differences are which two aspects can be ranked, which god speaks the waking-phrase, and the reagents you spend at the end.
There is exactly one hidden aspect per Nocturnal Arm, each named after an underworld deity from a mythology outside the Greek pantheon.
| Weapon | Hidden Aspect | Effect |
|---|---|---|
| Witch's Staff | Aspect of Anubis | The Ankh Scepter raises Lone Shades wherever you slay foes, scaling Omega move speed and damage. |
 Moonstone Axe | Aspect of Nergal | The Rock Lion Mace turns you Berserk after you strike enough foes. |
 Argent Skull | Aspect of Hel | Frost Mane grants the way of the Valkyrie after an Omega move, boosting attack speed. |
| Black Coat | Aspect of Shiva | Purifying Grace absorbs Omega energy into stacking Destructive Ranks. |
 Sister Blades | Aspect of the Morrigan | The Crow Cutters let you perform the ritual of Blood Triad for heavy burst damage. |
 Umbral Flames | Aspect of Supay | The Devil Sparks also enhance your Rush Boon damage. |
The names are a deliberate theme. The wiki notes each one connects to Melinoe 
or the game world: Anubis leads spirits to the afterlife, Hel rules a half-flesh half-skeleton underworld that mirrors Melinoe, and the Morrigan is a triple goddess like Hecate.
The hidden aspects vary from build-defining to niche, and a few are worth chasing as soon as you can.
Aspect of the Morrigan on the Sister Blades is the most explosive, since the Blood Triad ritual delivers some of the highest single-hit numbers in the game. Aspect of Shiva on the Black Coat rewards an aggressive Omega-absorbing playstyle that suits the weapon dash-in identity.
Aspect of Anubis is the friendliest first unlock, since the Lone Shades it raises add steady passive damage to a Cast build. The Nergal Berserk and Hel Valkyrie aspects reward weapons you already play aggressively, while Supay is for Rush Boon builds specifically.
Pick the hidden aspect for a weapon you already enjoy. They are powerful, but each one demands ranking a specific aspect to five first, which is a real Titan Blood investment. Unlock the one that improves your main weapon before collecting the rest.
Unlock the hidden aspect for whichever Nocturnal Arm you already main, because the level-five requirement means you should be invested in that weapon anyway.
If you have no strong preference, the Witch's Staff Aspect of Anubis is the gentlest entry point, since Cast-based Shade damage is forgiving and the Circe waking-phrase is easy to trigger. For raw payoff, the Sister Blades Aspect of the Morrigan rewards the investment most, but only if you enjoy the daggers fast, close-range style.
Across multiple runs, collecting all six is a long-term goal tied to the post-game, since each requires significant Titan Blood and the right god conversations. Treat them as milestones, not an early checklist.
There are six hidden aspects, one secret fourth aspect for each of the six Nocturnal Arms. They are the Aspects of Anubis, Nergal, Hel, Shiva, the Morrigan, and Supay, each named after an underworld deity from outside Greek myth.
Rank one of a weapon's named aspects to level five, then talk to that aspect's god with any weapon equipped until they give a waking-phrase, then activate the Silver Pool in the Crossroads to reveal the hidden aspect. After that you buy it with Tears and weapon reagents.
The Silver Pool is a feature in the Crossroads Training Grounds. Activating it after getting a god's waking-phrase reveals that weapon's hidden aspect so you can purchase it. Hidden aspects do not appear in the menu until the pool reveals them.
The Sister Blades Aspect of the Morrigan is the most explosive thanks to its Blood Triad ritual, and the Witch's Staff Aspect of Anubis is the friendliest first unlock since its Lone Shades add steady passive damage. The best one is whichever improves your main weapon.
The Aspect of Anubis on the Witch's Staff gives you the Ankh Scepter, which raises Lone Shades wherever you slay foes, and scales your Omega move speed and damage. It is unlocked by ranking the Aspect of Circe or Momus to five and getting Circe's waking-phrase.
It is the god tied to one of the weapon's two named aspects. For the Witch's Staff it is Circe. You talk to that god with any weapon equipped, not just the matching one, until they speak the cryptic line that lets the Silver Pool reveal the aspect.
Yes. The first step is ranking a regular aspect to level five, which costs Titan Blood, so each hidden aspect is a real investment. This is why it is best to unlock the hidden aspect for a weapon you already play often.
Yes, but it is a long-term goal. Each one requires ranking a specific aspect to five, getting the right waking-phrase, and using the Silver Pool, so collecting all six is tied to post-game progression rather than an early checklist.
