Thank you for taking the time to write this. I always wanted to test how the damage is calculated since i noticed that DEF debuff is better than ATT buff but didn't know the reason.

Noted that i have a fire team with Amaterasu i also have Gabriel to stack up two DEF debuffs, do you happen to know what are the percent values of those debuffs?

Amaterasu
-DEF debuff+(A) = -%?
-DEF debuff++(A) = -%?

Gabriel:
-DEF debuff+(B) = -%?
-DEF debuff++(B) = -%?
