I forgot to post this here with my charecter app so here it is.This technique can only be used in resureccion mode.The reason is because as I said before Froila obtains to Venus Flytraps on his back that can shoot cero or bala.What happens is the Flytraps and Froila all send out cero at the same time.
2 Flytrap Ceros+1 Froila Cero=3 So thats how you get Triple Cero
