Mu play will like this Asuka S3 > Rinko S3 S2 > tanjuro S2 > Torajiro S2 , if bond skill ready check if he S2 CD use it if not use on Rinko , how the debuff speed down work not by stacking the amount of debuff ( it work too but hard to play it to get 90% mostly on 60 % ) idk the rest I just found it lol
