Apparently, it looks like the Super ArmorTenacity passive doesn't work. With 100 ch4cka the damage must be much greater, but in fact the difference is insignificant, when there is a difference. I tested in several fights with -50 and 100 ch4cka and it changes practically nothing.

it should work exactly like Kakuzu [Earth Grudge] who has *most equal passive and, in his case, the damage changed drastically.If Kakuzu's damage increases, Sasuke's damage should also increase when he has 100 ch4cka
