Well I finally answered the question, I guess I mostly just get buff.

I guess overall in terms of raw ability nothing actually changes, just more of it will be willingly used. I imagine the actual animation would include the orb breaking as the rest of the the body changes, which if no one could tell right away was more or less directly pseudo inspired by Sol Badguy's Xrd install look. Just less drastic for myself overall. Also noting that the scarf is undone, possibly just as a trigger of some sort. I kinda view this as "Koja is treating this as silly rough housing (ala Slayer mentality), but at some point the opponent might have gotten a little serious and did a big "Do Not". Which is fuss with the scarf in a harmful way."
