AwesomeguytheMan's Yuumi Guide for People that Actually want

By AwesomeguytheMan
I Plan On Updating This Guide

I'll do my best to build on this guide and update it whenever Yuumi is updated even slightly.

Next Planned Update Back to Top
I'm going to try to learn the system a bit more so I can make this guide more visually appealing.
Put up a Pros and Con list.
Become better at Yuumi.
Yuumi takes Skill Back to Top

Look a lot of people see as a braindead champ even knowing the fact if someone who plays Yuumi for about 3 hours knows less then a pro-Yuumi, just want to make that clear before we get into this, Yuumi takes skill, it's a lot of timing.

Yuumi's Q Ability Back to Top

Yuumi fires a missile that deals, Lv.1 40 / Lv.2 65 / Lv.3 90 / Lv.3 115 / Lv.4 140 / Lv.5 165 (+30% of ability power) magic damage plus Lv.1 +3%/ Lv.2 +4%/ Lv.3 +5%/ Lv.4 +6%/ Lv.5 +7%/ Lv.6 +8% of target's current health as damage

If the missile is in flight/has been moving for 1 second, iLv.1 45/ Lv.2 80/ Lv.3 115/ Lv.4 150/ Lv.5 185/ Lv.6 220 (+40% of ability power) magic damage and applies a 20% slow to enemies for 1 second.

If Yuumi is Attached, she fires from her Ally and can control the missile for up to 2 seconds.

Mana Cost-Lv.1 90/ Lv.2 88/ Lv.3 86/ Lv.4 84/ Lv.5 82/ Lv.6 80

Yuumi's W Ability Back to Top

Passive: While Attached, Yuumi and her ally share

Lv1 12 / Lv2 14 / Lv3 16 / Lv4 18 / Lv5 20 ( Lv1 +12% / Lv2 +14% / Lv3 +16% / Lv4 +18% /Lv5 +20%) adaptive force, granting each other bonus attack damage or ability power (depending on which their ally has more of) equal to a percentage of their own attack damage or ability power (depending on which of the two is higher).

Yuumi starts the game with Lv.1 You and Me!, while Prowling Projectile has 6 Levels.

Active: After a 0.25-second delay, Yuumi dashes to an ally champion and attaches to them. While Attached, she follows her ally's movement and is untargetable by everything except TOWER DAMAGE. Yuumi's abilities fire from her ally's location, and she can't attack enemies.

Yuumi can switch among her teammates without a cooldown. If Yuumi re-activates the ability without a valid target, she will detach from her ally and dash up to 250 units in the target direction. Yuumi also detaches automatically if the ally she is attached to dies. Immobilizing effects (besides silences) on Yuumi places this ability on a 5-second cooldown

Yuumi's E Ability Back to Top

Yuumi heals herself for Lv1 70/ Lv2 100/ Lv3 130/ Lv4 160/ Lv5 190 (+40% AP) and gains 15% movement speed and

Lv1 25% / Lv2 30% / Lv3 35% / Lv4 40% / Lv5 45% attack speed for 3 seconds.

While attached, Yuumi's Ally is targeted by the ability instead.

Yuumi's Ult/R Back to Top

Yuumi recoils and opens Book, launching 7 waves of Lv1 60 / Lv2 100 / Lv3 140 (+20% of ability power) magic damage over 3.5 seconds. Enemy champions who are hit by multiple waves take only 50% damage from any wave beyond the first, and they are rooted for 1.75 seconds when struck by three waves.

During Final Chapter, Yuumi can move and cast You and Me! and Zoomies.

Also will say that I underlined the words in this section because these are really important to know.

When Drafting Back to Top

Look I've seen a concern that maybe people don't seem to understand, I don't and will not change my support after I have locked in my support as it is literally impossible and even if I could I wouldn't, The only person you probably couldn't support would be Kalista unless she is your Adc pick that happens before you get to pick; just suck it up as Yuumi is a decent support, also on a side note supports shouldn't let their adc pick their support pick, that's your judgement =3

The Adc's Back to Top

So as the support we will most likely go to the bottom lane (unless you have a stupid adc that decides he rather throw then let you actually play the game), so knowing this information, you will most likely be with your adc against the enemy support and adc. What you want in an adc is a semi-aggressive damage dealer that knows when to run/not-engage. Against an adc, if your teammate is close to dying and you're attached while the enemy is chasing towards the tower/teammates (this happens a lot), it is your goal to unattach and damage the adc as much as possible to either make it to where your teammate can turn around and kill the adc (or if it's Ezreal, Jhin, or Miss Fortune use ult) or kill them yourself and then RUN TOWARDS THE TOWER AND DO NOT ENGAGE WITH THE SUPPORT UNLESS THEY ARE BELOW 33% HEALTH. Fun Fact: most adc's usually go for a target that THEY think they can kill, so by unattaching you are disturbing the adc with some unexpected damage coming towards them possibly killing them.

Supporting Back to Top

Yuumi's love attaching, I personally recommend attaching as OFTEN as possible, if you see an almost-dead ally or a low health enemy, heal your teammate then un-attach to hit that enemy, also with most builds you have an effect for hitting enemies so pls hit them every so often. Remember do not take minions in the laning phase.

Yuumi's Most Important Skill Back to Top

Bop n' Block is a tremendous part of Yuumi's kit and is honestly so good that most Yuumi main's would recommend playing around it, it is a good shielding ability and one of the few things that encourages unattaching.

When to be Aggressive Back to Top

Look we all want to shoot a giant fireball at someones face utterly obliterating them for the face of the earth in several grams of sullen ashes, however, there is a time and place to do this. As Yuumi try to be aggressive when unattached but NEVER CHASE, chasing often leaves to inevitable death and failure or a stupid Master Yi to stab your cute kitten face with a sword. Use yourself as a scare tactic and if that doesn't work try to bait them under tower; several people underestimate how much damage Yuumi can do which means you can catch them off-guard and laugh on their corpse when they get killed by a Yuumi.

Under Tower Back to Top

Be aggressive, but there is a time farm a bit to wait for you adc. Try to hit them as soon as they think they are good to farm the tower, ignite them and watch them as they cry for their mama because they just died to a Yuumi, Lol.

When the Team is Toxic Back to Top

Sometimes your team will be arguable toxic but don't let get to your head, remember your their eventual savour late game so let that heroic action sink into your little kitten head.

Mid Game Back to Top

During the Mid Game/ when you defeat bots tower/ when they defeat yours, you will want to figure out who you can help, trust me any legend with a Yuumi attached is suddenly a lot stronger than usual so you are a really good legend to have around(trust me unless they are stupid they will accept your help), this sadly means your also the biggest target so be careful, your the number 1 priority not to die, so if you have to leave an ally to die do it trust me you're needed more than them

Attach Targets Back to Top

I would attach to your adc but sometimes you will have other legends that are more reliable, for example jungle is often a reliable target for an attach, I wouldn't trust mid unless they're fed, and top is a good attach but not great.Really just think about these aspects when attaching, am I keeping them alive, are they doing a lot of damage and getting kills, are you the reason they're winning team fights if all are yes then you picked a good target.

Late Game/Team Fights Back to Top

Yuumi is a literal saviour late game and is very impactful in team fights, she can easily use her ult to slow down or completely immobilize the whole enemy team for a good second, Also try not to die or let your carry die, you usually lose stuff at that point. But if they are dying and will die remember you don't need to die so let your carry die before you die
