The Arcanum Strategos are rituals that affect large swathes of territory or entire armies at once. Despite their wide-ranging effects, they are remarkably efficient in terms of ritual power needed to perform them — which makes the fact that they can only be reliably cast within Veilguard a constant source of frustration for military officers and economic advisors across the Continent. Though Veilwalkers are the only ones who can actually use them to their full effect, their massive practical usefulness during Churning means that they are passed down within the arcane traditions of every nation, to be pulled out and taught to Veilwalkers whenever the next Churning begins.
