The shield took the form of a tortoise shell, with faint blue lightning dancing all over its surface. If someone looked closer, faint sparks of whiteness could be seen flickering from time to time as well.
This was the final form of such mighty defensive technique. As Arthur summoned it, he felt his body being frozen and only his eyes could move with some difficulty.
He was raising his head to see the incoming attack, as if he was defying heaven. A single dragon standing midaid, surrounded by a semi-transparent shield and looking up towards a gigantic green fire tornado that was swirling towards him.
The tornado changed from a mere arc of green fire into a massive cone shaped mighty arm that was coming from above and pressing hard over Arthur's head. The closer it got to Arthur, the narrower its end became.
