A Spiritseer is an HQ choice available to the Craftworld Aeldari – known as the Asuryani – though they can also be called upon to join the Ynnari. Each is a skilled psyker on the battlefield, able to wield powers from the Ruins of Battle discipline. They work especially well alongside Spirit Host units such as Wraithguard and towering Wraithknights, where the Spiritseer’s otherworldly Spirit Mark will enhance the accuracy of the mighty ghost warriors.
