The Thunder Law is very powerful, belonging to the heavens and earth, a force like the majestic power of commanding thunder.
The sliver of Thunder Law awakened from his bloodline allowed Austin, even at the Gold Level, to catch a glimpse of the Legendary Level, rapidly increasing his control over various elemental powers.

The Law is a higher level of power.
Austin needs a more powerful offensive technique.
Especially in such uncertain prospects, having more methods never hurts, as strength is ultimately the foundation for surviving freely.
