犽宿+祕術拳擊S+Mystic Punch autos reduce all CDs by 1.25s; Yasuo's Q counts as an auto, so at 1.33s Q CD, you get infinite Q. Ruined King keeps shields up.
犽宿+暴擊治療SDoubles crit chance via passive — Ruined King alone takes you near max crit. Yasuo's high-frequency Q and E refresh shields constantly, while Death's Dance bleed makes him both tanky and bursty.
犽宿+巨像之勇氣AColossus's Courage + Critical Healing. Always Ruined King; with the wind, stack shields and engage.
