Is stackable the debuff of def of Bankai Yama with Minazuki debuff of deff?

Bindus

As the question is above, do these two debuffs of defense stack up together?

IoanaAnn

they should overwrite each other, im not 100% sure about this but if u dont see 2 decrease buff symbols they deffo overwrite each other and the last applied buff stays
(brenjis crit dmg buff and katen crit dmg buff stack for exsample u have 2 crit dmg buff symbols)
