There is almost no way that Claude can kill a veteran 6th fusion rank mage. He can only try to take some advantage by attacking first
The magic circle below Leon lit up and a bright and tall pillar of flame rose
The surrounding temperature instantly rose and the fire pillar causes the ground around Leon to be liquified
A spell of the 5th fusion grade is no joke!
Claude is currently in Ratois Mountain. He doesn't have to be worried that civilians would die and he can use any spell that he wants
The fire pillar reached the skies, piercing through a layer of cloud, giving off a bright light
This is not only in hopes that Leon would die from the spell but also a form of signal
A signal to Claude's reinforcements and also a warning signal for the people living near the Ratois Mountain to evacuate
When mages at their level fought each other, even mountains could be flattened!
