Mastery: Potent Afflictions is the Mastery for Affliction warlocks, improved by the mastery secondary stat.
Potent Afflictions increases the damage done by [Agony], [Corruption] and [Unstable Affliction], which are the main Shadow DoTs of Affliction warlocks, and [Seed of Corruption]'s explosion damage. Additionally, Potent Afflictions increases the damage done by [Phantom Singularity], [Siphon Life], and [Vile Taint], if the warlock is talented into any of these abilities.
