So, I had this idea of a skill and I went to ask a friend who's a been using the program, thing is, he never touched the rpg part, so he doesn't know that much about damage formulas, so might as well ask here:

So, what i'm looking is for a damage formula that goes like this....
basically the first hit will be normal, now, let's say the skill is a 3 hit, so after the normal one, the second will be weaker and the third more weaker....something like that
let's see if someone can help me with this.
