It was the players themselves who brainstormed and developed it.
Of course, it's also because Small Knife provided a large amount of basic runes and the learning cost was extremely low, coupled with the research atmosphere, that we have the current results.
Although crude, it is practical.
And there are teams researching it every moment, hoping to improve it.
If successful, they could make a huge fortune.

Although not yet on par with the Four Major Forces, if they digest this success, they might be the top force just under them.
They don't know, though, that this team, although it had the earliest idea, didn't develop the results themselves.
They are just lending their name.
Small Knife often checks some externally provided ideas and creative insights.
Seeing this defense mode is quite good, and the concept is promising.
