Dungeon Masters often struggle with calculating the area of effect on a grid. Xanathar's Guide to Everything provides clear templates and rules for cones, cubes, and spheres. If you need a PDF visual guide for spell areas, our tactical maps section creates easy references based on the book's rules. We help you decide who gets hit by the fireball without arguing over squares. Streamline your combat adjudication with the precise measurement rules offered here.
