DAWNSTAR saidYou don't really need to make your style based on your trait. Think of it this way. Zoro, Daz Bones, and Ryuma had this trait and later on, more swordsmen showed the same capabilities. Just treat the trait as a supplementary skill for your melee sword techniques. If you want range sword strikes, like Zoro's Pound Hos, T-bone's Angular Slash, or Kaku's Rankyaku, then focus on developing a technique that allows you to create a compressed blade of air.
*Flails helplessly* Rargh!
Trying to design a technique which focuses around the use of Vis's trait is difficult. The force of Vis's swing creates the pressure wave in an arc but mixing that with a dial is difficult. I can create the mist around Vis with dials but turning it into a weapon requires constant use of Vis's trait and is thus almost useless in close combat. Creating cloud based techniques that don't use dials would require Vis to swing hard enough to not only compress the air but also make a visible arc of air. Perhaps modifying a sword with a Jet dial would increase the force of the swing enough to achieve this.
As for your trait now, its probably my fault for not wording it better, but it is more similar to the ones I'll be showing you.
At 1:42 to 2:00. Both Zoro and Ryuuma made their slashes travel a greater distance due to their power alone. That's the trait I gave you.
