In the roguelike game Hades, Darkness serves as an essential currency that enables players to enhance Zagreus’s abilities for permanent progression. This is primarily facilitated through the Mirror of Night, located in the House of Hades. Below, I provide a comprehensive overview of how players can earn and spend Darkness, ensuring a deep understanding of its role in the game.

Earning Darkness

1. Room Rewards
– Primary Source: The most common way to earn Darkness is as a reward after defeating all enemies in a chamber. Typically, players receive 10 Darkness per chamber, although this amount can vary due to various game modifiers and the selected difficulty level.
– Chamber Preview: Before entering a room, players can identify whether Darkness will be the reward by observing the purple teardrop-shaped icon, which signifies that clearing that chamber will yield Darkness upon completion.
– Other Rewards: Certain rooms may offer additional Darkness under specific conditions, such as during special event encounters or through the use of certain talents from the Mirror of Night.

2. Charon’s Shop and Wells
– Charon’s Shop: During runs, players may encounter Charon, the boatman, who occasionally sells Darkness in exchange for Charon’s Obols (in-game currency). The standard trade rate is 25 Darkness for 25 Obols.
– Well of Charon: Players can also find the Well of Charon, where items like the “Tinge of Erebus” are available for purchase, granting a random amount of Darkness (ranging from 12 to 26), subject to varying prices.

3. Other Opportunities
– Boon Rewards: Occasionally, rewards from the gods in the form of boons or gifts may include Darkness.
– Special Events: Players can also gain Darkness as a reward from completing specific narrative events or quests throughout the game.

Spending Darkness

1. Mirror of Night
– Location: The Mirror of Night is accessible in Zagreus’s personal room within the House of Hades. Here, players can spend Darkness to unlock and enhance various talents that improve Zagreus’s abilities.
– Function: Each talent requires Darkness to unlock or level up, with options available to increase health (e.g., Death Defiance), dash capabilities (e.g., Greatest Reflex), or attack power (e.g., Fiery Presence).
– Cost Escalation: The cost of upgrading talents increases as players progress through the levels. Higher tier upgrades can demand substantial amounts of Darkness, ranging from 500 to 1000 for some final upgrades.
– Unlock Requirements: Certain Mirror talents are initially locked; players must use Chthonic Keys to unlock these before spending Darkness on them.

2. Resetting Abilities
– Respec Option: As players advance further in the game, they have the option to reset all Mirror talents for the cost of a single Chthonic Key, allowing for a strategic reallocation of Darkness to different talents.
– Respec Cost: Respec does not consume Darkness and allows players to reset their investment but does require a Chthonic Key for each reset.

Additional Notes

– Persistence Through Death: One of the appealing aspects of Darkness is its persistence; players retain all collected Darkness even after dying, ensuring that it is not lost between runs.
– Central to Progression: Upgrading talents in the Mirror of Night is crucial for making Zagreus more robust and versatile in his attempts to escape the Underworld.
– Complementary Currencies: While Darkness is a vital currency, players should also consider other currencies such as Chthonic Keys, Gemstones, and Charon’s Obols, which serve different progression purposes.
