History
Originally, Essentia was used by the Immortals, and the Shadows could decrease the amount available to the Immortals by raiding the Vault. In the September 21, 2023 update, Essentia was completely removed from the Immortal mechanics. However, it continues to appear for Shadows raiding the Vault.
