If a Tiny creature (like a Pixie) shares a square with a Medium creature (say human), are they considered adjacent to each other?
Adjacent Squares: Two squares are adjacent if a side or a corner of one touches a side or a corner of the other. Two creatures or objects are adjacent if one of them occupies a square adjacent to a square occupied by the other.
I can see a topological argument that by its very nature the corners and sides of a square are touching other corners and sides of the same square. Is this a case of nitpicking the RAW to pieces? What are the ramifications?
