New subfactions allow you to tailor each army to your favoured play style. The Thousand Sons boast a total of nine Great Cults, each with a distinctive psychic power, Warlord Trait, and Relic. The Grey Knights have access to eight new Brotherhoods, with signature Stratagems, psychic powers, and Warlord Traits. These subfaction psychic powers are taken in addition to the powers they already know, empowering your Psykers without taking anything away.
The Grey Knights and Thousand Sons have a lot more in common than either of them would ever care to admit. In some ways, they’re a twisted mirror of each other, and never is this more apparent than when they meet on the battlefield. They both want to prove their superiority, and the titanic forces they unleash upon each other are enough to shatter less stalwart minds.
Let’s have a look at a few of those new powers, to get a glimpse of what’s to come.
Wardmakers
This Brotherhood spends as much time honing their ritual discipline as their battle skills. They’re able to strip elite soldiers and fodder like cultists of their sorcerous protection, leaving them vulnerable to massed storm bolter fire or heavy weapons fire.
Cult of Time
The sorcerers of Tzeentch, for their part, can simply hit the rewind button if one of their own has their time cut short. Imagine the look on your opponent’s face when you return a Scarab Occult Terminator, simply erasing the hard work they put in to take it down.
Swordbearers
If the Grey Knights want to make sure they inflict more casualties than the Thousand Sons can undo, they’ll call in the Swordbearers’ contingent of tanks and gunships. Few units can withstand concentrated heavy fire from this Brotherhood.
Cult of Knowledge
The Thousand Sons are jealous of all power, and their answer to the Empyric Lodestone is Empyric Trespass. It works in a twisted way, of course, but it’s extremely effective in softening up a juicy target.
Prescient Brethren
The 4th Brotherhood has weaponised a similar sort of mental manipulation, amplifying and returning the enemy’s fear in the form of excruciating psychic feedback.
Cult of Manipulation
When all else fails, the arrogant and headstrong Sorcerers of Tzeentch will resort to simply trying to force their will upon other Psykers in a psychic wrestling match. What a power move.
