So I'm writing a pretty cool story idea right now about superhumans and culitvation. Now, when I was writing it, I figured it needed a power scaling method, something similar to ranks and realms and stages like in cultivation. But I don't see how cultivation ranks would work with superpowers. Then, I came up with the idea to use a scaling system similar to the ones they use in jojo. Right now, I have it down to these five

Power - destructive power of ability (power to generate explosions)

Range- effective range of the power (can use their power miles away)

Speed - how fast they can move (super speed)

Trick - creativity when using power (if someone can shoot energy blasts from their hands, but figures out they can shoot lasers from their finger tips or create energy explosions)

Toughness - how hard they are to hurt (invulnerability or high-speed regeneration)

I'm also thinking of using the letter grade system like they do in JoJo to detail how powerful the super human is. From E (slightly more powerful than an ordinary human) to S (natural disasters in the shape of humans)

This is one of the few stories that I have written down that I think holds real potential. So I'm a little nervous about the scaling system, and I would like feedback on it and ideas on how to improve it, if possible.
