Sam forcefully pushed the hammer off of him and took a few steps back to get out of the range.
He used the energy vision to quickly observe the energy flow within the coat and got ready to fight back.
The quality of the fire element of the demi giant is actually quite high, even the soil below which is clearly used to the extreme heat was still charred a bit because of the flame attack.
As the giant pursued Sam, he also lunged forward and swung his blade as he halted the attack mid-air by blocking the hammer at the handle.
Even though, he was spared the impact, the flames still exploded after the contact and they surrounded Sam.
Sam's own flames are of extremely high quality and they are one of the purest fire elements to ever exist, so even if he couldn't use the element directly at the moment, he can endure a relatively inferior quality fire attack on him for quite a while.
