All human (and mostly-human) characters have three Stats that rate basic ability in certain key areas (ie: they provide the number of dice rolled in tests): Body, Magic and Tech, and each stat is linked to a number of Skills (fodder for a later post).
Characters who decide to follow one of the transformative Paths (or who have already done so at character generation) do not, however, have this exact trio of stats. To emphasis the effects that such a dramatic change has upon the character one of the stats is swapped for another (depending on the Path taken):
Non-humanoid characters use entirely different sets of stats to describe their basic abilities within the context of their species, for example; Singers use the stats Avatar, Melody and Rhythm.
