The Mirror of Night in Zagreus's room.
| “ | Within the Infinite Dark, Everything | „ |
The Mirror of Night, located in Zagreus's room, was a gift from Nyx to Zagreus to aid him in his attempts to escape the underworld. It is one of the main meta progression systems in Hades.
Reflecting at the Mirror gives Zagreus the ability to spend Darkness gathered from the Underworld to improve his own abilities. However, many of the abilities are locked at first, each requiring a varying number of Chthonic Keys to unlock. After several escape attempts, the ability to refund spent Darkness for use on other abilities is unlocked. Refunding Darkness costs one Chthonic Key and refunds all Darkness spent in the Mirror of Night.
Each ability from the Mirror has two versions, one colored red and one colored green (the green talents are not available from the start — they will be unlocked following a conversation with Nyx after collecting a minimum of 300 
). Each version needs to be invested in separately. For example, spending Darkness on Shadow Presence does not upgrade Fiery Presence. Only one version of each ability can be active at a time, and they can be switched between freely while reflecting at the Mirror.

Totals
It takes a total of 65 to unlock all upgrades on the Mirror.
To unlock all non-Boon, non-Fated Authority upgrades requires 6,165 ; including the Boon upgrades takes this total to 14,365 . Including Fated Authority and Fated Persuasion, the total required to max out the Mirror is 35,365 .
Fated Authority
One point of Fated Authority can be used to change a room's reward into any other item from its pool. Room rewards belong in two distinct item pools.
One pool consists of permanent resources, indicated by a blue laurel wreath on the door:
- Chthonic Keys
- Gemstones
- Darkness
- Nectar
The other consists of temporary (run-specific) resources, indicated by a golden laurel wreath around the door:
- All Boons
- Daedalus Hammers
- Charon's Obol
- Centaur Hearts
- Poms of Power
Some rooms cannot be altered, nor can they be acquired through Fated Authority: Charon's shops, friendly NPC encounters with Sisyphus, Eurydice, and Patroclus, passageways through Underworld areas, and boss rooms. Mini-boss encounters can have the reward altered, but the encounter itself is unaffected; all standard encounters can be altered by Fated Authority however, including skull symbol rooms turning into regular rooms (and vice versa)
Notes
- Dark Regeneration benefits from Dark Thirst
- Boiling blood does not gain additional benefits from having more than one
in the same enemy. Also, some god Boons that affect your Cast actually prevent from getting stuck in a target and therefore block you from benefiting from this damage boost (such as the ice beam of Demeter), others modify how it lands (for example, the chain-lightning strike of Zeus will stick the in the very last enemy hit by the shot) - Fated Persuasion restocks the Well of Charon if an item was purchased prior to usage
