This is the set I generally use for T4 yorcia. It's not really practical dps wise but with riverfin soup, focus, and a marcato'd madrigal, it puts you at 1161 accuracy. It also provides a decent chunk of defense along with some pdt since the mandy sometimes likes to triple attack followed by a headbutt right after.

Otronif body is augmented with 10acc 4pdt/3mdt, qaaxo legs and feet are both rank15 path B.
I tend to stick with this set due to the fact that whenever we do yorcia, I'm usually tri boxing whm and brd and my main focus is on dispelling the regen and waking people up after dream flower.
