Destiny 2: Heresy Introduces The Tome of Want and Essence of Desire

The new episode, Heresy, adds unique progression mechanics and resources like Essence of Desire to enhance gameplay in The Nether and Dreadnaught.

The Tome of Want allows players to focus and customize loot drops by using Scriptures and Essence of Desire, offering targeted rewards like weapons, armor, and resources.
Essence of Desire is a key currency in Episode: Heresy, used for activating the Tome of Want and unlocking bonus chests in The Nether and Dreadnaught.
Players can acquire Essence of Desire by completing Nether runs or exchanging 10 Metastasized Essentia at the Taken Altar in Eris Morn's apartment.
Metastasized Essentia, a resource found in The Nether and Dreadnaught, must be refined during runs to be usable for rewards at the Taken Altar.
The Shaping Slab, located in Eris Morn's apartment, serves as the main vendor for Heresy, offering Runic Enhancements and permanent upgrades through the Mysterium system.
