Problem
Ryu immediately began to draw in the air with a finger, comprehending the technique from Ailsa's memories.
The Divine Mark was like an exceptionally layered formation fit into the form of a maze of sorts. Just trying to memorize the form of a single Divine Mark could make one's head spin.
From what Ryu could tell, there were thousands of nodes, hundreds of layers, and it all had to be packed into the size of a palm. The amount of control it took to form one was ridiculous. But, the amount of skill it took to sustain it and stop it from shattering after just a single use in battle was even more ridiculous.
Ryu ran into problems almost immediately. The main issue was that his lightning was no longer pure lightning.
