Message: <blockquote data-quote="Felix" data-source="post: 3160247" data-attributes="member: 3929">I believe that the light emanating from the large creature would act in the same way that a mounted character acts on his horse; he's considered to be in every 5-ft square at the same time for purposes of reach and threatened areas.So for your large creature, the light would extend 20 feet to the East of points C and I, 20 ft. South of points I and G, 20 ft West of points A and G, and 20 ft North of points A and C. Then connect the edges. Shadowy Illumination extends in a similar manner, but goes 40 ft out from those points instead of 20, and starts where the clear illumination leaves off.For folks with Low-light Vision, the clear illumination extends 40 ft instead of 20 ft, and the shadowy illumination extends to a radius of 80 ft. ---For a medium sized creature occupying the square A-B-E-D, the light would extend 20 ft North, South, East and West from those points.---No, this does not render a Light spell that provides light in an area with a diameter of 40 ft, but rather 45, but this is done in the name of simplicity and conformity with the two principles that a spread spell effect is centered on a grid intersection, and that a character occupies the entire 5-ft square. It makes light spells and darkness effects carried by a character slightly bigger, but it solves the problems created when you force them to choose an intersection. This is done for simplicity's sake and not realism.---Note that this means that if Light is cast upon a stone and carried, it will have a 45-ft diameter effect, but as soon as that stone is thrown, it will land on an intersection and thence have a 40-ft diameter effect; until picked back up, that is.</blockquote>
