• With Yuumi attached, a bruiser assassin such as Kha’Zix can pick off low-health champions while Yuumi deals damage through the round; burn items and augments such as Runecarver and Righteous Fury have time to stack.⁴
• A healing and shielding build alongside two bruisers works well.⁵
• Yuumi with Warmog’s Armor is a cheese build.⁶
• Righteous Fury is recommended for full-damage Yuumi.⁷
• A full-damage Yuumi strategy has Yuumi spend the round hiding while a hard-to-chase teammate keeps the main hiding champion alive.⁷

• With a Kayn teammate using his ultimate, Yuumi can deal heavy damage to one enemy by spamming Q.⁸
• A Yuumi carried by a teammate with Trueshot can nearly one-shot enemies with the augment.⁹
• Yuumi’s critical healing can replenish an ally’s entire health bar while the ally is under anti-heal.¹⁰
• With enough haste, Yuumi can stack shields and nuke enemies when she leaves W.¹¹
• Yuumi can speed up an ally’s Warmup Routine (level 2) while mounted by dancing during cooldowns.¹²
• Locket works well on Yuumi and gives large shields.¹³
• Serpent’s Fang is a good choice against Yuumi because her shielding is strong.¹⁴
• Bel’Veth alongside Yuumi can be a strong pairing, though a melee champion might be one-shot before Reaper’s Toll can kill enemies.¹⁵
• Yuumi can work well with a carry, even though few augments or items work well directly on her.¹⁶
• Jeweled Gauntlet with adaptive force and Muramana is a Yuumi build.¹⁷
• Autocast Yuumi alongside Autocast Singed is an unconventional build.¹⁸
