In today’s Grotmas Calendar, the Thousand Sons try to influence the battlefield in the Hexwarp Thrallband
The empyric ritualists who lead the thrallbands wield magic without restraint. They seek to shatter the veil between reality and the Warp, empowering their arcane arts and unleashing daemonic energies upon their weak‐minded foes. Directing mindless Rubricae to seize sites of power, these Sorcerers tap into the wellspring of potential, weaving obscuring rituals and killing spells. As the tide of arcane energy builds in strength, the battlefield comes alive with mutagenic energy, enhancing the Sorcerers’ magical power and haloing their thralls in fulminating coronae of uncontrolled arcane force. With warpflame and hellfire, they sweep the enemy from the field of battle, and Tzeentch claims the souls of the dead.
When Thousand Sons models in this army make psychic attacks, they can re-roll wound rolls of 1 if they are within a part of the battlefield that they control; they swell with the Warp and instead, add 1 to the wound roll for their psychic attacks as the battlefield is saturated with the Warp.
With the Arcane Might Enhancement, characters can draw upon the rampant Warp energies to add 1 to the Strength characteristic of Psychic weapons equipped by the bearer’s unit. While the bearer’s unit is wholly within the army’s Flow of Magic, add 2 to the Strength characteristic of Psychic weapons equipped by models in that unit instead.
With arcane energy flooding the battlefield, the veil between Warp and reality rapidly collapses. From yawning rifts Rubric Marines can arrive from Strategic Reserves as if they had the Deep Strike rule, and Scarab Occult Terminators can take advantage of the disruption to deploy from Deep Strike just over 6” from enemies if they are deployed wholly within the army's Flow of Magic by using the Through the Veil Stratagem.
That’s the entertainment sorted for Grotmas, but what about the lights? The Adeptus Mechanicus are seeing to the electronics tomorrow…
