7 pp = 10 damage
8 pp = 12 damage
9 pp = 14 damage etc
This is the baseline assuming that you have double roach (or a way to bounce it), carbuncle, and enough 1 costs to fill out the rest of your pp.
Every 0 cost from here on is +2 damage
No buncle is -2 damage
Nature's guidance instead of 2 roaches or staff bounce is -1 damage
There are edge cases where the calculations are different, I just yolo those or calculate manually lmao
