That is another theory that I had not considered, but I wasn't precisely suggesting harmonics as the reason for differing affects of investiture. According to the Standard Model of particle physics, both matter and energy are made of particles called fermions and bosons, respectively. WoB has stated that there is a triad between matter, energy, and investiture, suggesting that investiture is also made of another class of subatomic (or in this case subaxial) particles, particularly since it may exist on its own and become sentient. There are 24 different types of fermions and I think maybe 9 different bosons, so it follows that there would be different types of investiture particles as well, which could be arranged into things similar to atoms depending on the fundamental forces acting upon them. Due to the existence of anti-investiture, investiture particles must have charges so it could be assumed that something that is invested is simply attracting investiture particles towards it. This may not be the electromagnetic force however, since magnets do not seem to have an affect on investiture.
