Rem furrowed his brows, he incredibly doubted that the attack from the Death Wolf Boss would be able to destroy the Holy demon. He didn't stop gathering magic for his own strike, all of it seemed a bit too easy.
And the smoke cleared shortly after, revealing the Holy demon with several large holes in it's body, it's arms had been dismembered and it's head had been blown off – the extent of the damage was not something that was negligible but it had been expected that the Demon would recuperate immediately, instead it took time for the flames to gather in the respective holes and even more time for the wounds to regenerate.
'So it's running low on Magical energy,' Rem thought and thrusted his other hand forward, this was a situation where he had to exploit to the maximum, "Strike it!"
