I have an idea.
Have the item use up every combo token on every character - and then the damage dealt to every enemy is 4 to the power of the number of combo tokens expended.
So if all 4 enemies have a combo token each, now it does 256 damage.
Most confession bosses won't be fazed due to the lack of enemies on the field... unless they started spewing combo tokens on your party...

idk if im using this thing wrong but it kinda sucks. I really like the idea but losing a combo just for 2-3 damage doesn't seem worth it to me. I kinda figured it could only be used on enemies with a combo but still keeps the combo. I guess id have to try it more to see where it would be applicable, i do see the value like on a melee character that has no other skill options available but i feel like that's just a team building issue at that point.

Strange, I don't seem to get the same bug. If you're using any of my other mods, do you get the same bug?

When I found the item in the first inn the item icon was white and when I equipped it the combat the combat item tab doesn't show next to the other skills. I don't know what triggered the bug tho.
