Infernal Masters forge pacts with daemonic entities, referred to in the lore of Prospero as tutelaries. Chanting jagged syllables and making promises of blood and souls, they unleash the powers of these malign familiars to engulf their foes in swarms of momentarily corporeal terrors, to divine whispers of the future, or to master the currents of the warp itself.

The Infernal Master empowers your Thousand Sons force through a variety of potent Infernal Pacts, enhancing allies and debilitating foes with the trickery and insight of his daemonic familiars. A psyker himself, the Infernal Master can also wield powerful sorcery and challenge enemies leaders to combat with his coruscating force stave.
