Area Of Effect

Spells such as burning hands and cone of cold cover an area, allowing them to affect multiple creatures at once.

A spell's description specifies its area of effect, which typically has one of five different shapes: cone, cube, cylinder, line, or sphere.

Every area of effect has a point of origin, a location from which the spell's energy erupts. The rules for each shape specify how you position its point of origin. Typically, a point of origin is a point in space, but some spells have an area whose origin is a creature or an object.

A spell's effect expands in straight lines from the point of origin. If no unblocked straight line extends from the point of origin to a location within the area of effect, that location isn't included in the spell's area. To block one of these imaginary lines, an obstruction must provide total cover.
