Bash

Deal 1d8 bludgeoning damage to one enemy. When you hit an enemy that is weak to bludgeoning for the first time this turn, take one more action this turn. Costs 7%hp. On a natural 20, deal 2d8 and act as if you hit the enemies weakness

(This is for a homebrew persona campaign I'm making. More Personas and spells will be made as time goes on. A feat has already been made called the "Persona User (Wild Card). If anyone has any tips, feel free to provide them)
