40k had a whole ton of Chaos stuff going on for a few months there. But while they swap over to a new sector with the Squats, it's Age of Sigmar's turn to get some of that Chaos love. In this instance, it's a look at Battletome: Disciples of Tzeentch.
From the article:
Change is in the air, quite literally – Screamers of Tzeentch and Tzaangor warriors on living discs scream through a sky turned kaleidoscopic by gouts of unnatural magical flame. Battletome: Disciples of Tzeentch is on its way, and the scheming Scintillating Hosts have seen their rules mutate into new forms at the touch of the Changer of the Ways.
Whether through legions of cawing Tzaangor and mortal Arcanite cultists or multitudinous hordes of ever-shifting daemons, the Disciples of Tzeentch wield supremacy over magic. Endless Spells are drawn along with these hosts, sustained by the aura of sorcerous energy.
