Well, while we're on the subject of luck.... how is pride and vigor accurately measured?

Both give a set increase (although to different parts of the damage formula). And then there's the fluctuation based on HP.

In the case of vigor, it's easy to have full effect at some point, but then luck could have a kami get combed down to low HP and lose full effect on that kami.

On the other end, pride needs low HP to have full effect (5% in fact which is very dangerous). You might again see only 1 kami get potshotted that low...

How much are these fluctuations actually contributing to overall damage? Cause it's honestly quite random and theoretically, the average increase should be looked at
