Champion Stats
Low elo players do not know how to focus the carry when a Yuumi is attached. They waste cooldowns trying to poke you (which you shield) or engage on your host (whom you heal). Her Q (Prowling Projectile) is now a steered missile that applies a slow and on-hit damage buff, allowing your ADC to chase down kills they would otherwise miss. The 'Best Friend' passive rewards you for sticking to your smurf duo, granting them increased healing and shield power that scales into the late game.
The Attach Cheese
Start Q (Prowling Projectile). It is one of the strongest level 1 trading tools if you land it. Steer it around minions to hit the enemy ADC. The slow allows your ADC to land 2-3 free autos. If they try to trade back, your Passive shield negates their damage. You win the attrition war before the lane even starts.
Your passive 'Bop 'n' Block' is the key. Detach, auto, and reattach for the shield. It's worth the risk early. The slow on your Q is disgusting for setting up ganks. You're a magical cat; lead your 'Best Friend' to victory.
When They Ban Yuumi
If Yuumi is gone, Lulu is the best 'buff-the-ADC' pivot. If you want more healing, Soraka. But nothing replaces the 'untargetable' feeling. The book stays closed today. Meow elsewhere.
Lulu for the shield/polymorph. Soraka for the heals. Milio for the range. Lulu is the active version of 'making your carry unkillable'.
Leveling Yuumi's Abilities
Max Q first for the poke damage and slow strength. Max E (Zoomies) second for the shield and attack speed buff. W is maxed last as the % healing scales with ally level mostly.
Mastering Yuumi's Kit
Prowling Projectile. Steerable missile. If it hits an enemy, it deals damage and slows. If sitting on Best Friend, it also grants on-hit damage.
You and Me!. Attach to an ally. Untargetable (except towers). Grants Adaptive Force (Removed in rework? No, grants finding Best Friend stacks mostly now/Healing on-hit).
Zoomies. Grants a shield and Attack Speed (and Move Speed). Restores mana to ally? No, just Shield/AS/MS now.
Final Chapter. Channels waves that damage and Slow enemies. Heals allies. Massive AoE tool.
Matchups That Matter for Yuumi
The hard counter. He isolates your carry and kills them, leaving you helpless. Ban him or dodge.
Dangerous. His execute ignores your shields. You cannot save your ADC from R.
Kill Lane. If she engages, you must respect the CC chain.
AFK on ADC Syndrome
Do not detach in a teamfight unless you are 100% safe! The rework removed your passive mana restore on autos, so there is LESS reason to detach aggressively. Your job is to stay alive and keep the 'Best Friend' alive. If your host dies, you are dead. Also, don't sit on a tank if your ADC is the win condition; build the Best Friend bond with the carry.
Don't just sit there! Aim your Q, time your E for the burst. A good Yuumi is proactive. Your R 'Final Chapter' is a massive healing wave—use it to turn a fight. You're the battery pack of the team. Power.
When Your ADC Is Doomed
Dodge Mordekaiser. If he Ults your host, you fall off and die instantly. Nautilus is annoying because he can hook you if you ever detach.
Hop on the Jungler. Hecarim/Kayn/Master Yi. They are the carry now. Mute the ADC.
Dodge Morde. He ults your carry, you fall off and die. Dodge Nautilus. He hooks you mid-air. Hostage lane. Just go next.
Peel or Engage?
Press R (Final Chapter) when the enemy engages. It heals your team and slows the enemy massive amounts. Use E (Zoomies) to block burst damage on your carry. Land Qs to slow fleeting targets. You are the battery pack. If your carry is a hyper-carry (Twitch, Jinx, Zeri), you basically allow them to 2v5.
R is both. Root enemies. Heal allies. Passive shield blocks damage. Stay attached to the most fed person.
Ult to slow their engage. E to shield the burst. Q to poke/slow. You are an item. A broken, speaking item. Make your carry look like a smurf.
The Book Cat Build
Full AP On-Hit Yuumi (with the right partner). Imperial Mandate -> Ardent Censer -> Staff of Flowing Water. Your Q applies Mandate, your E applies Ardent/Staff. Your carry becomes a machine gun of buffs.
Mejai's is actually viable if you're on a safe hyper-carry. You're the hardest person to kill if your host is alive. Moonstone and Ardent are your core. Buff them to the heavens and watch the pentakill. Best friend.
Moonstone -> Ardent -> Staff of Flowing Water. Buffbot supreme. Your carry gets attack speed, move speed, and infinite shields. You get LP.
Yuumi's Strongest Moments
Level 6. The R healing is massive. 2-Item spike (Ardent + Moonstone/Mandate) makes your host incredibly tanky.
Level 6 for the R-healing. 2-item enchanter spike. Level 11 with the 'Best Friend' scaling. By late game, you're importantly a seventh item for your carry. If they're alive, you're winning.
Level 6. R is a massive teamfight tool. 2 Items. Late game you are a stat multiplier. A 6-item Jinx with a Yuumi is a 7-item Jinx.
The Untargetable Cat
Spamming 'You can't catch me!' emotes. Mastery flashing every time your carry gets a kill. The simple existence of a Yuumi tilts the enemy team because they feel it's 'unfair' to fight a 2-health-bar champion.
The psychological damage of Yuumi is your best weapon. They'll focus everything on your carry, who has two health bars thanks to you. Mastery flash when they fail to kill you. You're a cat—you have 9 lives. Use them.
Spam emotes. Type 'Meow' after every kill. The enemy hates you. Use that. They will dive your carry recklessly just to kill you. Punish them.
