    Space, Reach, & Threatened Area Templates

    2d Grids and Planes or 3d Cubes and Spheres?

    Are spell and other area of effects 2d (as in, they affect a flat grid only) or are they 3d (as in, they affect cubes and spheres)?

    Just because things are normally expressed on a flat grid doesn't mean they're actually flat. Any effect with a radius affects a sphere, not a circle. A cone is a 3d area. A line is a line, not a plane.

    This page includes examples of creature's sizes, space they occupy, and various area-of-effect templates to aid you in visualizing combat and encounters.

    Area of Effect Templates

    Some spells affect an area. Sometimes a spell description specifies a specially defined area, but usually an area falls into one of the categories defined below.

    Regardless of the shape of the area, you select the point where the spell originates, but otherwise you don't control which creatures or objects the spell affects. The point of origin of a spell is always a grid intersection. When determining whether a given creature is within the area of a spell, count out the distance from the point of origin in squares just as you do when moving a character or when determining the range for a ranged attack. The only difference is that instead of counting from the center of one square to the center of the next, you count from intersection to intersection.

    You can count diagonally across a square, but remember that every second diagonal counts as 2 squares of distance. If the far edge of a square is within the spell's area, anything within that square is within the spell's area. If the spell's area only touches the near edge of a square, however, anything within that square is unaffected by the spell.

    See Aiming a Spell for full details.

    Circle (5' radius)

    As is the normal with most area of effects, the caster or source of the effect must select an intersection of squares as the center of the effect. In the circle templates below the intersection is indicated.

    Cone (30')

    In the cone templates below "C" is the caster of the spell or the origination point of the effect. If "C" is replaced with (c) that indicates that the caster may choose one of the (c) positions.

    Line (30')

    A line-shaped spell shoots away from you in a line in the direction you designate. It starts from any corner of your square and extends to the limit of its range or until it strikes a barrier that blocks line of effect. A line-shaped spell affects all creatures in squares through which the line passes.

    In the line templates below "C" is the caster of the spell or the origination point of the effect.
