A Primaris Librarian is a capable warrior and a powerful psyker who can manifest powers from the debilitating Obscuration discipline. He wears a psychic hood, granting him a better chance of thwarting the powers of enemy psykers. Like many other Vanguard units, the Primaris Librarian in Phobos Armour also wears a camo cloak to enhance the effects of cover.
This multipart plastic model comes in 10 components and is supplied with a Citadel 40mm Round Base.
You’ll find the full rules for the Primaris Librarian in Phobos Armour in Codex: Space Marines.
