@Galaxian and Peter
Meliodas is 1.25 times baseline, and Drole
staggered him and
made him bleed (note the small blood mark near the mouth), he could withstand a kick from Meliodas and Zeldris
w/god (this was before he
increased in power with a commandment), and
magic on Estarossa's level heavily injured him. So just 6-B rather than + makes more sense, well in my opinion anyway.
Zeldris did cut off his arm, but it was with a weapon. Zeldris' actual physical strength is 47,200, which is lower than Derieri's 48,000, and Demon Mel's 50,000.
He waited for the exact moment until his neck was immobilized before doing that, allowing him to restrain Estarossa.
Here's my interpretation. What are your thoughts?:
Mel, Zeldris, Derieri (via crippling Meliodas, and somewhat fighting with a revived one), and Estarossa are Low 6-B+.
Gloxinia, Drole, Critical Over Galand, Monspeet (he has a similar combat class to Derieri, but nowhere near the physical feats), Fraudrin, Melascula (fought a half power clone of Meliodas, which had a PL of 30,000, but he was outclassed), and Grayroad are Low 6-B.
Galand is Likely High 6-C, possibly Low 6-B.
Gowther (Demon) is Low 6-B, possibly Higher.
Edit: Didn't notice Raven's.
