"Intermediate Combined Fire and Wind Magic: Causa Satani ventus malleo!!" The two simultaneously shouted. Translation: EX-PLOSIVE WIND HAMMER!! 

*BOOOOM!* 

The loud sound of an explosion followed by a giant shockwave and gust of wind passed through the whole room. 

There was so much wind pressure that John felt like he would've been blown away out of the Arena if it wasn't for the fact that he could use wind magic. 

Both Serena and Ariel who were closest to the explosion, seemed to have some sort of wind barricade around them which stopped the pressure from blowing them away. 

Master Sylvia on the other hand, was the only one that didn't use magic and took the pressure on. But despite being hit by it, she wouldn't move and kept a poker face on as the Air flowed through the hair. 

She looked unfazed from her perspective, but from john's perspective, he felt bad for her hair and quickly formed an Air bubble around the two of them.
