How to Farm Spectral Ashes
The best way to farm Spectral Ashes is to participate in the Apparition Incursions – a seasonal exclusive event that is the only way you can farm Spectral Ashes. The drop rate of Spectral Ashes scales primarily with each difficulty tier, meaning that higher difficulties will result in even more drops. Defeat enemies and bosses to complete the event and gain Spectral Ash rewards.
