Grim Dawn's Occult Skill Mastery Announced, Screenshot

Crate Entertainment has revealed a third skill mastery for Grim Dawn, simply called "Occult". A single screenshot depicting one of the mastery's skill effects can be found in our image gallery, while a quick rundown is below:
It is still early in development and anything could change. So far though, it is shaping up to include two powerful pets, crippling debuffs, and damage over time spells. The first pet is a mystical great raven, a familiar that supports the Occultist with healing spells, buffs, and attack spells of its own. The second pet is a hellhound with vicious melee attacks and hellfire breath.
