As I look at the beast a Seventh stage one well let's do this as I rush at the beast landing several hits but I also take hits an equal fight it tries to land a finishing blow but I am able to defend most if not all the attacks and then he jumps back and he starts to suck in energy No.This can't be happening a--a Self destruct i say and as I try to block him in I Yell

EARTH WIND BARRIER And as I try my best to keep the explosion in a small spot not to let it escape cause if it does I and a huge part of the lands will be destroyed there is a reason its a forbidden spell and as the explosion happens it seems I contained it but the the barrier falls as I look at the core a white core it's releasing explosions I have to destroy it but how
