Burst

Intro
Burst was a very rarely seen specialty because it would trigger spontaneously.

Effect: Your tough soul doesn’t match your frail body. Up to a certain limit, you can burst out strength exceeding your body’s. However, there will be serious side effects afterward.

Usage
There was no daily use limit, but Marvin knew that it didn’t have many uses.

This was also a very precious specialty, that Marvin could trigger whenever he wanted.

He obtained this speciality after his life and death battle with the Marcus Thieves Society in Ch. 84
