User blog:Patrick x hunter/difference between emission and transmutation0

I noticed under silva zoldyck Nen ability description its says "Silva can transmute his aura in two large orbs that retain frightening power even after being emitted" and its listed as both emission and transmuter abilities. I don't think making his nen into orbs floating would count as a transmutation ability since when Gon practiced his emitting skills on greed island to hit a rock from afar it also was an orb, so I feel its a stretch to say its transmutation, I think its only emission. I could be wrong but I just thought id bring this up, since its a bit confusing and could effect other descriptions.
