How to unlock weapon aspects in Hades 2
To unlock weapon aspects, you must complete the “Aspects of Night and Darkness” incantation at the Cauldron. This is the concrete unlock requirement; without finishing that incantation, the extra aspects won’t appear.
During early access, many players reported learning the incantation after defeating Hecate with each weapon. However, experiences varied: in one run-through the incantation appeared at the Cauldron after defeating Chronos twice, even before Hecate had been beaten with every weapon. In short, the exact moment you learn it can differ between playthroughs.
After you complete the incantation, head to the Silver Pool in the center of the staging area. There, you can view the available aspects and their unlock costs, and then spend the required materials to add them to each Nocturnal Arm. 
All weapon aspects in Hades 2
Each Nocturnal Arm has four aspects in total — three that become available via the “Aspects of Night and Darkness” incantation and one hidden aspect. Below are the three default/unlockable aspects for each weapon, with short descriptions and their unlock costs.

Sister Blades
Melinoë — Your attacks and specials deal more damage by striking foes from behind. Unlocked by default.
Artemis — While you channel your Ω attack, you occasionally parry, then riposte right after. Unlock cost: 15 silver and 1 glass rock.

Argent Skull
Melinoë — Your attacks have more power for each shell fired and not yet retrieved. Unlocked by default.
Medea — Your attack stays within reach, and explodes after landing your specials or three seconds. Unlock cost: 1 mandrake and 4 iron.

Black Coat
Melinoë — Your attacks, sprint, and move speed are faster. Unlocked by default.
Selene — You start with Sky Fall, a hidden Hex that strikes multiple foes and applies Shine. Unlock cost: 4 silver and 4 moon dust.
Nyx — You have Ω boost, which lets you produce Nightspawn after you activate it. Unlock cost: 4 flux and 1 darkness.
Finally, remember that aspects can reshape how a weapon feels. Therefore, once the incantation is done, visit the Silver Pool and try different aspects to find the playstyle that fits you best.
