It was said that Gladsheim could reduce a country to ash
and it was only a test of power, Gladsheim scales to Reinhard and Methuselah. We should calculate this feat but for now we can give it 6-B or 6-B+. Because it was only a test of power and even couldn't really damage Gladsheim and destroy one single soul of Gladsheim.
It was also said that Gladsheim energy was comparable to the most historic earthquakes in history, and that Gladsheim made this energy just by running.
The strongest earthquake in history Valdivia Earthquake had a magnitude of 9.4-9.5. It is 6-B+ and consistent with last one.
Nvm valdivia earthquake happened in 1960 while the Interview with Kaziklu Bey happened around world war II so we can't scale Gladsheim's earthquake to valdivia earthquake but we can scale Gladsheim's earthquake to
1585 Aleutian Islands earthquake (Magnitude 9.25),
1730 Valparaíso earthquake (Magnitude 9.1-9.3),
1737 Kamchatka earthquake (Magnitude 9-9.3), still making Reinhard and Methuselah At least 6-B+, likely far higher. Because their power is much higher than that earthquake feat.
It was said that Methuselah darkened the sky, and it was a sign of a calamity, like a tsunami that could sink a entire continent, but that was cleary just a theory and vague. Because it said that sign of a calamity, "like" a tsunami. But no one knew what was really going to happen. Although maybe we should calculate this too?
So for now we can give Methuselah at least, 6-B+, likely far higher
Reinhard will be at least 6-B+, likely far higher too
