Hi, my name is Bizzleberry and I am a longtime League of Legends player, playing since before Season 1. Over the years I have achieved high ranking in solo queue, from Platinum in Season 1 (the highest at the time) to Challenger multiple times throughout the years. I used to stream in season 4-5 and stopped playing League for a year during season 6. I have now returned and am currently in Master as a support main. You can catch me on my stream or my Youtube channel. I try to explain what I am doing in most situations; feel free to ask any questions on stream or leave a comment on the guide!

Yuumi is a very unique champion in which she is able to attach to allies and be immune to almost all-damage and able to cast skills and abilities still based on where the ally you are attached to is. In large teamfights this means you are able to dash around to the front line in order to set-up big AoE plays or stick to kiting and hunting down an enemy trying to escape!

Yuumi has the option of taking NO escape summoners, so she is able to use Exhaust and Ignite in the laning phase enabling both you and your ADC to hairball, i mean, snowball early!

You also do NOT need boots and can save yourself a lot of money early and push yourself closer towards a Mythic Item before the enemy support can!

Current strongest Build

---

Summon Aery Provides minor poke damage on both your Q and your Auto Attacks, and also provides a minor shield when you heal or whenever you attach to a new ally.

Manaflow Band

---

Manaflow Band Is the only clear option here, gives you a little bit more mana regen, although not really needed, the other 2 runes in this branch of Sorcery are really bad for Yuumi.

Transcendence

---

Transcendence is a huge way to get a lot of Cooldown Reduction early. Very easily the best option here.

Gathering Storm

---

Gathering Storm is massively better at 10m+ than Scorch.

Secondary Runes

Precision

---

Presence of Mind

---

Presence of Mind Will give you extra mana throughout the game which is much needed, especially early. Will also give you mana during teamfights which during early laning phase can be really clutch to save an ally due to the extreme mana costs early.

Cut Down

---

Cut Down give a minor DPS increase because Yuumi's base HP is very low so it will be easily to get some benefit from this rune.

Yuumi has the luxury of not needing Flash and Ghost as You and Me! attaching tool allows you to dart around enough as it is and will help you avoid damage.

I would advise you to go Ignite AND Exhaust. This will give you a lot of aggression for early in the laning phase to get a quick kill.

Other options could include, Yuumi taking Heal and the ADC taking Barrier or Teleport. The downside is Yuumi will very rarely need the heal, so your ADC could be healing another target and speeding them in at later teamfights.

PASSIVE

Bop 'n' Block

When you auto-attack when your passive is ready, on an enemy champion, you will get mana and a shield. This shield will be given to whoever you then decide to attach to unless either the shield depletes or you un-attach to your ally. You will need to decide when it is safe to attack for the mana - which you will need to do, as Yuumi has mana issues early. Sometimes the shield will be consumed in an auto-attack trade just so you can get the mana.

Q

Prowling Projectile

A projectile that fires in a straight line when unattached, or if you are attached, will briefly follow your cursor for a few seconds then disappear. Once the projectile has been out for 1 second it will deal increased damage and slow.

You will be allowed to put 6 points in this skill unlike the normal 5 as you start with your W included level 1.

Learn to wave this ability inside minion waves (inbetween the melee and caster minions) for the best surprising hits!

If you suspect an enemy to be hiding in a bush, use this spell around the entirety of a bush, if Summon Aery is released then you know someone is there!

You can use this to 'bait' shields from enemy supports and then quickly switch to the other target. This tactic is particularly useful against Sivir.

Max this first if you are going AP YUUMI


W

You and Me!

This is Yuumi's attach skill and she starts with it level 1 for 'free'. You remain untargetable and will not be effected by things like skillshots or Karthus Ultimate.

If you are unattached and get hit by crowd control, that will put this ability on cooldown for 5 seconds and leave you extremely vulnerable to attacks.

If you attach while under Ignite or with other DoT Damage then you will still take damage by it!

If you damage an enemy under tower when attached, you can still take tower aggro.

E

Zoomies

If unattached will heal yourself, give you movement speed and attack speed. If attached to an ally will give them the bonus effects listed above instead. If running Moonstone Renewer then try to wait until it is fully charged before healing for a bigger heal.

Careful not to use this 'too much' as the mana cost is EXTREMELY HIGH


R

Final Chapter

Casts waves out of Yuumi in a set direction. Can be interupted if UNATTACHED. If attached to an ally then it cannot be interrupted. If an enemy champion gets hit by 3 waves then they are rooted. You may want to unattach off an ally to be able to 'control' the direction of the waves.

Spellthief's Edge

---

Spellthief's Edge has now changed to auto-upgrade to Frostfang (500 gold collected) and Shard of True Ice (1000g collected) from the Tribute gold quest. You are now allowed to receive gold from hits on enemies / turrets without an ally nearby. You can also 'accidentally' get cs from throwing out skillshots in lane without being punished (Until you meet the Support Rule CS Limit which won't kick in until around 30-40 Creeps Taken, depending on what time it is in the game).

Shard of True Ice

---

The final Support Quest upgrade. You will no longer generate tribute gold, but the stats on this item for 'free' are very good for mid-game and also supply you with 4-ward charges that can be refreshed when you go back to the fountain.

ITEMS FOR ENCHANTER YUUMI - SCROLL FURTHER DOWN FOR AP YUUMI ITEMS!

Moonstone Renewer

---

Yuumi is one of the best enchanter supports that can use Moonstone Renewer. You will naturally get a lot of healing off on this item as you and your ally will be on combat a lot which will ensure the ramp up of healing on the item. Try to wait until it has stacked 5 times for a stronger heal.

Chemtech Putrifier

---

When you shield an ally or heal them you will make their next attack / ability apply 60% grevious wounds. This item is very strong with it's base stats alone and very cheap and will also interact with the healing from items, such as Moonstone Renewer. Currently the best legendary item for the Enchanter version of Yuumi support. You could even run this second item in the AP Yuumi Build

Redemption

---

Redemption is currently one of the best utility support items in the game. It is a soft counter to poke comps, but is usually purchased because of the versatility of the item. Provides a massive heal AoE heal, at a very long distance and can be used while dead. It can be a massive game changer when used in the centre of a teamfight.

Ardent Censer

---

Ardent Censer works best with an auto-attacking hypercarry such as Vayne or Kog'Maw.

staff of flowing water

---

Staff of Flowing Water is not a great option. I would only purchase this item if I find myself wanting to attach to a heavy AP user. Enchanter Yuumi item only.

Mikael's Crucible

---

Mikael's Blessing is an OK item. It no longer heals and provides the target with a cleanse. If you are quick it can disable Death Sentence but would likely be used to stop basic annoying cc such as Wither, Frenzying Taunt, stuns and fears. I only recommend this for experienced players due to the fact that having to pay attention to so many things already that keeping an eye for CC also can be a bit too much.

AP YUUMI ITEMS

Luden's Tempest

---

Ludens provides Yuumi with a huge damage boost in her harassment with Prowling Projectile while expensive, you should only be using AP Yuumi if you come out of laning phase with an a lead, and you will need to identify this very early on.

Horizon Focus

---

Horizon Focus continus to increase your damage while also providing a reveal factor to your Prowling Projectile.

Rabadon's Deathcap

---

Rabadon's Deathcap is an extremely expensive item but worth it if you can purchase it. ONLY purchase if you get INCREDIBLY FED!

Chemtech Putrifier

---

When you shield an ally or heal them you will make their next attack / ability apply 60% grevious wounds. Run as a second item if you are against a lot of healing. Still provides a nice chunk of AP and some extra mana regeneration.

Void Staff

---

Void Staff provides a huge chunk of magic pen. Can be effective even as early as a third item if the enemy team is stacking magic resistance. Will give you more damage than a Rabadon's Deathcap if they are.

During the laning phase, your Q Prowling Projectile is on a relatively high cooldown so be active and un-attach from your ally often. Auto attack minion waves to try and get a level advantage and try and proc Bop 'n' Block as often as possible to provide your ally a shield when you use You and Me! back on to your ally.

Prowling Projectile should be used often as possible during the laning phase. If your ally is too close to a unit in melee range, you will need to spawn Prowling Projectile behind your ally and do a huge curve back in to get to the target in front. This is to ensure that the bonus damage and slow take effect.

Zoomies has one charge at a semi-large cooldown however provides a massive heal and attack speed to your target. Gives a lot of healing once you acquire %healing items. Try not to use too often as the mana cost on this spell gets VERY costly and the you will need to auto whenever your passive is ready on an enemy champion to recoup some of that mana cost.

In fights try and be as active as possible and prioritise surviving over everything else. For example, if the enemy jungler is coming down, try and use Prowling Projectile to slow the jungler to give yourself more time to get to the turret. Use Zoomies for the extra movement speed to help dodge engaging skillshots. Detach and Auto for Shield with Bop 'n' Block.

Try and save your ultimate Final Chapter for when you get tower dived or setting up a fight. Don't forget you can use You and Me! to another ally and continue the channelling and you can detach to help re-angle your ult if your ally is going the wrong way.

In some certain matchups - usually against hard engage tanks like Nautilus or Rell you may want to stay attached more than normal so you don't get caught out. Be smart and only un-attach when you are certain they will be unable to crowd control you.
