You have learned how to change how your bombs explode. Whenever you craft a potion, you can change the explosion from its typical area of effect. If changing from a line AOE (Area of Effect) to any other shape you will halve the distance. And the reverse is true as well when changing any other AOE to a line. For example, a bomb with a 30 ft line effect will effect a 15 ft, sphere. And a bomb with a sphere of 30 ft, will change to a 60 ft line. All other transformations utilize the same dimensions.

Cone

A cone extends in a direction you choose from its point of Origin. A cone’s width at a given point along its length is equal to that point’s distance from the point of Origin. A cone’s area of Effect specifies its maximum length. A cone’s point of Origin is not included in the cone’s area of Effect, unless you decide otherwise.

Cube

You select a cube’s point of Origin, which lies anywhere on a face of the cubic Effect. The cube’s size is expressed as the length of each side. A cube’s point of Origin is not included in the cube’s area of Effect, unless you decide otherwise.

Cylinder

A cylinder’s point of Origin is the center of a circle of a particular radius, as given in the bomb's description. The Circle must either be on the ground or at the height of the Effect. The energy in a Cylinder expands in straight lines from the point of Origin to the perimeter of The Circle, forming the base of the Cylinder. The bomb’s Effect then shoots up from the base or down from the top, to a distance equal to the height of the Cylinder.

A cylinder’s point of Origin is included in the cylinder’s area of Effect.

Line

A line extends from its point of Origin in a straight path up to its length and covers an area defined by its width. A line’s point of Origin is not included in the line’s area of Effect, unless you decide otherwise.

Sphere

You select a sphere’s point of Origin, and the Sphere extends outward from that point. The sphere’s size is expressed as a radius in feet that extends from the point.

A sphere’s point of Origin is included in the sphere’s area of Effect.
