犽凝+祕術拳擊S+Mystic Punch autos reduce all CDs by 1.25s. Yone's Q counts as an auto, so at 1.33s Q cooldown you get infinite Q — pair with Ruined King for permanent shield uptime.
犽凝+穩紮穩打SSlow and Steady converts attack speed to AD without reducing Q's cooldown — Q's tooltip damage is already huge.
犽凝+暴擊治療SDoubles crit chance via passive — Ruined King alone takes you near full crit. Yone's high-frequency Q refreshes his shield while Death's Dance bleed makes him both tanky and bursty.
