Hey guys! Hanjaro here!
A little bit about me
I started playing League in Season 1, towards the end of the season. Since the beginning I was a support main, I enjoyed the 2v2 dynamics much more than 1v1s so I've stuck with it throughout my league career.
I have achieved the rank of challenger at multiple points during seasons 4, 5, 6, 7, 8 and 9, and continue to push for the highest elo I can get.
I love competitive games and have yet to find anything for me that compares to League.
Aside from League, I am a happily married man, father of 2 kids and I am a beloved pet owner. If you guys have any questions about my guides, champions or really anything in general, feel free to stop by my stream!

Why Yuumi?

Yuumi is a unique mage enchanter, she is able to attach to her allies and be able to cast all her abilities, and items, while being immune to most damage, and cc. You can play up in the frontline, healing and shielding your tanks, while slowing and rooting enemies to catch them out.

If you enjoy playing, or want to learn more about Yuumi, you can read and discuss more over at

Summoner Spells Back to Top

Yuumi is primarily attached to her allies during laning period and team fights, so realistically taking Flash is just a waste of a summoner - shes so squishy, that she would be dead before you have the chance to Flash!

Heal and Ignite are good summoners to use if your ADC is taking Teleport - that way you have the defensive and offensive summoners, and have the ability to get back to lane asap after backing - which you can take advantage of with You and Me!.

The reasoning behind Ignite is that it gives you a lot of extra pressure in lane, and furthermore adds a 40% healing reduction. You may want to hop off your ally to cast this, as more often than not, their auto attack range is lower than Ignites range. Only do so if it's safe!

Exhaust is used when there are high damage threats on the enemy team, such as Zed, Kayn, Draven etc - and without Flash, it's the best summoner to take alongside Ignite.
It gives you an extra chance at escaping with the damage reduction, as well as the slow it provides. The damage reduction can be used to negate all in damage, from something like a Zed's Death Mark.

Runes Back to Top
Sorcery + Precision

Summon Aery procs when you use You and Me! - (only when leaving and re-attaching!) giving you extra utility and shielding. It procs with Zoomies, adding a shield anytime you heal your ally, and it's a fantastic way to proc Ardent Censer.

Manaflow Band is the only viable rune in this column, it helps with your mana regen and is invaluable to your early game poke - every time it's available, make sure to Q.

Transcendence is your best go to rune here, we're focusing on maximizing our CDR and being a healbot for our carry, and all of our support items contain CDR.

Gathering Storm is the best option here, you'll gain permanent valuable stats over the course of the game, increasing the longer the game goes on. Scorch is just not worth it anymore, as we're not focusing on the damage our kit can do - spoiler, not much!

Biscuit Delivery helps with our mana sustain in lane, and increases our overall mana permanently. This is very useful as we're no longer taking Athene's Unholy Grail as core item, so we have less mana regen than previously.

Cosmic Insight synergizes well with Transcendence, and provides us with extra CDR on everything, including active items - which is the main point of our build.

Itemization Back to Top
Yuumi unfortunately does not do much damage anymore after the 9.24 changes, so it's increasingly difficult to stack Athene's now. We also don't need the extra healing due to the buff we received, so this isn't a core item anymore - but it can still be taken if you feel you need the extra oomph.

Redemption offers an aoe heal in an area, adding an aoe health sustain for her allies that Yuumi's kit lacks. It also offers HP and Mana regen, meaning you can stay in the fights longer, recall less, and you can help out even while dead. It also offers an extra 10% shielding power, which synergizes with your Summon Aery.

If you have a team comp that relies heavily on fast auto attacks such as Vayne, Kindred, Quinn etc. Ardent Censer is a great pickup to maximize your carries damage output while shielding them, it also offers you a bit more burst, a small bonus to your movement speed which helps roam to ward as you're generally not buying boots, mana sustain and 10% CDR.

The Dark Seal > DAMAGE/MANA
If played right, it's very unlikely Yuumi is going to die often while even or ahead. Dark Seal gains stacks extremely fast in mid to late game, offering you a very nice chunk of AP, increasing synergy with nearly all your abilities. Generally not necessary to build anymore, we're not using it for damage and we want to be focusing on increasing our healing as much as possible.

A good pick when facing an enemy team with hard CC that you need to Cleanse on allies, such as Impale, Dark Binding, Cocoon etc and grants bonus movement speed for 2s after successfully cleansing an ability.
Increases your Mana and HP regeneration, and 20% shielding power - good synergy with Summon Aery. We want to be buying every item with forbidden idol, and this is no exception.

Shurelya's Reverie > UTILITY/HEALING
Another forbidden idol item is Shurelya's, and is a necessity to our healing build. You also gain an active item aoe movement speed buff, which not only helps us get alone solo if necessary, it helps with engaging and fleeing for your entire team.

If the enemy team has a lot of healing such as a Soraka or Sona, you may want to rush Morellonomicon for the grievous wounds passive it applies. You gain 70 AP to add onto your burst window, magic penetration which can help burst through tank threats with AP resist. It's better to focus on your support items ahead of this, but if none of your team are building grievous wounds and you desperately need the healing reduction, consider this.

If your team is lacking much CC, or slows, you can take this to catch out enemies a bit faster, you can activate it while attached with You and Me!. It gives you 80 AP, so a nice chunk of burst damage, 600 mana to keep your mana healthy, and 10% CDR. It's generally taken with Glacial Augment rune, which is only taken on Yuumi if you need hard disengage (not advisable..!).

  • You can use Prowling Projectile for the slow (20% at all ranks since 9.19) to catch up to a fleeing enemy.

Gameplay Back to Top

Early Game

During the laning phase, you don't want to be attached to your ally the entire time, knowing when to detach is what makes Yuumi's high learning curve. You want to bait enemy spells such as Light Binding, or Bone Skewer, and then use You and Me! to reattach before they collide with you - if you get immobilized by this, your You and Me! goes on a 5s cooldown, you'll most likely be dead! Be very careful, as Yuumi now has a short channel on her W. Detach to use Bop 'n' Block when off CD, and reattach to provide your ally the shield - you can do this when safe in a fight - this is harder to do now with AoE CC, be aware of your inability to reattach on immobilization for 5s.
Prowling Projectile is mostly used for proccing Manaflow Band, and stacking our Spellthief's Edge. It's damage has been significantly reduced, so we tend to max Zoomies first, due to the insane buff it received, along with the ardent-like attack speed.
Hooks, displacements, knockups all can cancel your You and Me! mid dash, so you want to be very careful not to get caught out like this.
Keep your ally topped up with Zoomies, and be aware it no longer has 2 charges, it's just like a normal ability now - but it's a lot stronger, and no longer needs your ally to be low on health to get the maximum effect out of it. Don't leave your ally 1v2 while attached, you want to have presence in lane, even if it means just taking a couple of poke hits for your ally. Do be sure not to get caught out by CC or you're just a free kill.

Mid - Late Game

Outside of laning phase, you're going to want to be setting up a lot of Warding Totem wards around objectives, such as Baron Nashor and the drakes. If your team is ahead, and it is safe to do so, you can set up deep vision in the enemies jungle, allowing yourself and your team to get important picks, that allow you to take the previously mentioned objectives. You rarely want to go alone as Yuumi, you will not be taking Boots of Speed, and with the lowest base HP in the game, you can easily turn the game into a 4v5.

Mid/late game you nearly always want to be attached, if the enemies have backline divers, you want to be focused on peeling for your ADC with Final Chapter, and healing them to full with Zoomies.
You can use your tanks and bruisers to make them an unstoppable force, granting them insane amounts of AD and essentially making them unkillable with your Zoomies and Bop 'n' Block.

You want to be able to root as many enemies you can during a teamfight with Final Chapter, you can use You and Me! to reposition this if your attached ally heads the wrong direction!

Yuumi wants to focus on building as many Forbidden Idol items as possible to increase her shielding and healing power, which is the core part of her playstyle now instead of being an untargetable AP carry! With the four core items built from Forbidden Idol, you gain a crazy amount of healing and shielding boost, and can heal up anyone (even tanks!) from half HP to full with one Zoomies, and the extra CDR we gain from all of these items, means we have a lot less downtime.

Yuumi's playstyle has changed significantly since her release, going from doing an incredible amount of damage, to an insignificant amount, but increasing her heal immeasurably. She has also received an ardent-like attack speed buff to her Zoomies, which does stack with Ardent Censer. We also prefer to max You and Me! over Prowling Projectile, providing your ally with a nice extra chunk of stats. We're basically like a playable item!

The main thing to be aware of, is making sure your teams threats stay alive, while removing, or zoning, the enemy teams threats.

Control Ward's are a staple part of any support, both to deny your enemies vision, and to provide your team extra vision. You should make sure to buy one at least every time you back, preferably to have 2 on you at all times.
Conclusion Back to Top
I hope you enjoyed, and learned enough from my Yuumi guide, to play her as well as the pro's.

If you enjoyed my guide, you can check out my other guides here, in which I've covered more styles of supports, incase you want to branch out on supports such as engagers ( Nautilus, Pyke etc!).

If you're interested in seeing more of me, please follow my stream! I stream every day but Saturday, from 12:00pm - 11:00pm GMT. I play a wide variety of supports, and I am always engaging with my stream chat.
