Randomly swishing blade at body parts is generally my take on it.
Jk, I usually just tell the reader what style a character is using, but when I get a little more technical I use what I was taught in MMA for basic blade slashes. *stab, vertical up, vertical down, horizontal left/right, diagonal one, diagonal two, diagonal three, diagonal four, stab temple one, stab temple two* nothing too flashy usually.
If you suddenly gained the force, and total mastery over it, what is the very VERY first thing that you would do?
