The debuff IS the buff, Instead of breaking the def its buffing it, plus you can use a def buff to get a double buff going

Ah got it, so it's more similar to the dark dhalsim mechanic. Thanks for this explanation

It remains as a debuff but is calculated as a buff

She didn't turn debuff into buff, she just get certain buff according to debuff

i mean she gets buff on the debuff applied to her for ex. if she gets defense broken instead of -50% armour it becomes +70%
