Serene glanced at Terrin and answered while conjuring up a ball of fire that circled around her body.
"My style of burning is self-taught. It involves layering the fire multiple times and concentrating the flame such that it gains actual volume. That is, I could hit you with it and you would feel an impact. It wouldn't feel as painful as an impact from a normal weapon, but then the burning starts. It's also easier to aim since it's not an abstract idea. That said, I didn't deliberately create this style. It was a side-effect of me trying to find ways to make my fire cuter. Like so."
As the ball continued circling around her, it morphed and changed, parts of it forming into legs, then a tail, then a head. Finally, Serene was no longer being circled by a fireball. In its place was a fiery squirrel that excitedly ran rings around her. She laughed and tickled the fiery creature under the chin with her armored hand, then let it dissipate into nothingness.
"I don't know if you can do it with thunder, though. Thunder's form is a lot more volatile than fire's. It's definitely possible to gather lines of thunder together to make simple weapon shapes, but I haven't had success with anything more complex."
