Kairos' Fragments of Magic skill allows him to equip fragments of other spell lores, giving him access to several spells from the equipped lore, with the caveat that only one fragment can be equipped at a time. Like every other unit in Tzeentch's army, he comes equipped with Barrier, a shield that recharges out of combat, acting essentially as an additional health bar, encouraging a hit-and-run approach to combat. The Daemons of Tzeentch are led into battle by Kairos Fateweaver, a two-headed being that boasts 'unsurpassed magical knowledge and capability,' being aware of both the past and the future, yet unable to see the present at it unfolds.
