[10.22] PH45's guide to Kai'Sa, Daughter of the Void!

By PH45
Hello, I'm PH45, and this is my Kai'Sa Guide.

My real name is Patrik, but you can call me either way. I am a long time League of Legends player (started back in Season 1). I mostly play top lane, where my main champion is Jax, but lately I've expanded my interest to other roles. I have been Diamond since Season 7.

Kai'Sa is an interesting champ in that fact that while she is designed as an AD carry, she has both AD and AP scalings on her abilites, meaning she can be built AD, AP or even hybrid. This makes her a very diverse champion.

My OP.GG for anyone interested.
Back to Top

Flash: For Kai'Sa we will be going with the standard ADC summoner spells, and the first one is Flash. Helps you get out of sticky situations (Flash over walls etc.)

Heal: Can save you and your support in some cases, or even other teammates, also the small movespeed burst is nice in some cases.
Back to Top

+ Great range with Void Seeker
+ Hybrid ratios on Q,W and R
+ Has invisibility with evolved Supercharge
+ Can disengage and also re-engage quickly if needed
+ Can build items like Zhonya's Hourglass and utilize it fully

Kai'Sa dashes in-and out from combat and can also peel for herself with her shields, which makes her a great carry champion.

- No CC
- Weak to CC
- To evolve all abilities you need to build AD, AP and attack speed, which can be difficult to do in some games depending on the opposing team
- Can't control Icathian Rain

I actually think there are multiple rune sets that you can run on Kai'Sa. I myself like to go either Fleet Footwork or Press the Attack like most of the time on ADC's but it depends on matchups etc also.

Precision fits into Kai'Sa's playstyle and kit quite well, so it's a solid tree for her to take.

The two keystone of choices for Kai'Sa, are either Fleet Footwork or Press the Attack. Fleet Footwork helps your early sustain in lane and also the movespeed boost combined with Supercharge can help you catch opponents. The movespeed boost also helps with your low attack range since it helps you chase down opponents at least a little bit. Press the Attack amplifies your and others damage on the target after you proc it, which helps you take down targets faster.

Next one on the list is Triumph. It replaced Dangerous Game and can save you in a clutch situation or just grant you some HP back in a intense teamfight. You can also take Presence of Mind since the extra mana will be really useful for a champion like Kai'Sa.

Overheal seems to have taken a stroll into becoming more meta, especially if you play with Legend: Bloodline and Fleet Footwork. Allows you go get some shielding to make your trades a bit easier for you.
Next are the Legend tier runes, from which we either take Legend: Alacrity or Legend: Bloodline. I have started to like Legend: Bloodline on a lot of champs, but the attack speed from Legend: Alacrity is a pretty nice for Kai'Sa. Both are fine choices
Lastly from the Precision tree we have Coup de Grace. I feel Coup de Grace will get most reliable use out of the 3 rune choices. With Coup de Grace squishy targets melt faster and when you get tanks to lower HP they start melting as well.

For the second tree I most of the time run Sorcery, due to it offering good scaling runes for late game.

Absolute Focus is really nice. The extra damage it offers while being above 70% HP is pretty neat to have, especially once you get some sustain/have shielding so you are actually staying above 70% HP.

Basically, the longer the game goes, the stronger you come. Gathering Storm gives you great scaling, especially towards late game where Kai'Sa truly shines.

Domination also works on Kai'Sa, it offers some sustain, and also a bit of penetration for your spells.

Sudden Impact is pretty meh, but still offers some extra damaging capability once you start using your ult. Taste of Blood will help you sustain during early trades in lane, to get you to scale for later parts of the game.

I like Ravenous Hunter a lot. Once you get the stacks on it the healing is pretty great, which allows you to survive in fights even if you don't build lifesteal.

Nowadays people run Inspiration on ADC's to compensate for weak early game since you'll get sustain from cookies and you can invest gold elsewhere due to getting free Tier 1 boots with Magical Footwear.

Allows you to sink gold into other things, since you'll be getting essentially 300g for free, only con is that you have to wait out for them for a while.

Gives you extra sustain for lane, allowing you to deal with even more poke-oriented and rough lanes.
Back to Top

  • Second Skin (Passive):
    CAUSTIC WOUNDS: Kai'Sa's basic attacks, Void Seeker Void Seeker and nearby allies immobilizing effects mark enemies with Plasma for 4 seconds, stacking up to 4 times. At 4 Plasma stacks, Kai'Sa's next attack ruptures the target, dealing damage based on target's missing health as bonus magic damage, capped at 400 against monsters.

    LIVING WEAPON: When a certain stat reaches the required amount, Kai'Sa can evolve the related basic ability. This has a channel time of 2 seconds, and the upgrade will be canceled if the requirement isn't fulfilled anymore.

  • Icathian Rain (Q): Kai'Sa releases a swarm of 6 missiles that evenly distributes among nearby enemies, each dealing physical damage. Non-minions take 25% damage from missiles beyond their first. This is your main damage ability, which you will be maxing first for that reason. Great ability otherwise but you can't really control where the rain hits other than just standing near your target/targets.

    LIVING WEAPON: Requires 100 bonus attack damage – Icathian Rain fires 12 missiles and deals 100% increased damage against minions below 35% health.

  • Void Seeker (W): Kai'Sa fires a Void blast in the target direction, stopping at the first enemy hit, dealing magic damage, revealing for 4 seconds and applying 2 Plasma stacks.

    This is one of your key assassination abilities. You use this combined with Killer Instinct to dash to your target and burst them down.

    LIVING WEAPON: Requires 100 ability power – Void Seeker applies 3 Plasma and refunds 70% of the cooldown against enemy champions.

  • Supercharger (E): Kai'Sa charges for 1.2 - 0.6 (based on bonus attack speed) seconds, during which gains bonus movement speed, increased by 0% - 100% (based on bonus attack speed).

    After charging up, Kai'Sa gains bonus attack speed for 4 seconds.

    LIVING WEAPON: Requires 100% bonus attack speed - Supercharge grants invisibility while charging.

  • Killer Instinct (R): Kai'Sa dashes to a target location near an enemy champion with Plasma and shields herself for 2 seconds on cast.

Back to Top
Doran's blade
Basic starting item. Gives a good amount of HP and some AD in addition. Good for lanes where you feel like you wont get poked down too hard.

Doran's Shield
Pick this up for lanes with lots of poke. Kai'Sa doesn't have that strong early so she will get poked down quite easily and you can't necessarily respond to the damage quite at the same level.

Rapid firecannon, range is power
Great item for Kai'Sa. Often times I go this item as it helps you poke your opponents. It gives you extra range on the empowered auto attack once this item stacks up.
Infinity Edge
Gives a good amount of AD, and is actually a good first item again since it gives crit chance again. Overall makes your crits do more damage so as you get more crit the more DPS you'll have.

Phantom Dancer
Gives crit which is important, and some attack speed. It also gives a shield in the same way like Sterak's Gage and Maw of Malmortius so this item gives you some protection vs assassins.

Blade of the ruined king
A bit more niche item on Kai'Sa now that Guinsoo's Rageblade became her core item. It can still occasionally work and its good that it gives some sustain but pick this up only if you are facing a lot of high speed tanks Singed etc.

Runaan's hurricane
Great item, improves Kai'Sa's waveclear and also lets her spread her on-hit onto multiple targets.

Guinsoo's Rageblade
Very strong item on Kai'Sa but the changes in 8.23 made it better for hybrid builds as it now offers hybrid penetration instead of AD and AP. Testing currently a new build suited for this item.

Lord Dominik's regards
Helps really a lot dealing with tanks especially late game where they have 4-4.5k HP.

Berserker's greaves
Pretty standard boots for ADC's. Gives you attack speed and movespeed. In some cases you can substitute for Ninja Tabi but in my opinion this is important for your DPS especially early. When you have these and Guinsoo's Rageblade you have enough attack speed to evolve Supercharge

Guardian angel
Really strong item to pick up, gives AD and a so called second chance for a pretty cheap price.

Mortal Reminder
Good item if you are facing a lot of healing in the opposing team. Especially if the enemy team has a Soraka or Swain. Helps you kill them faster and also gives you armor pen which is always nice.

The Bloodthirster
Gives you lot's of sustain and damage, and the shield helps especially a lot in teamfight's once you stack it up.

Maw of Malmortius
Good item to get if enemy AP carries/carry is fed and you can't avoid their damage.
Gives nice amount of damage and also gives you some sustain after the shield procs. Don't buy both this and Phantom Dancer as the lifeline passives don't stack.

This item was made to give crit again so it can be beneficial in some builds since it gives AD, AS and crit. It no longer amplifies Energized procs, but rather sends out a 0.5 second 75% slow which can come handy in some cases.
Back to Top
At level 1 you almost always want to try and push the wave on bot lane to reach level 2 before your opposing bot lane does. Taking Icathian Rain at level 1 helps you accomplish this quite easily. Pushing the wave also helps you create a bigger wave, thus you'll have better trades.

Depending on what kind of support you are laning with and what are you laning against, you can look to potentially fight at level 2/3. If the matchup is unfavorable you can try to freeze the wave by only last hitting minions. After a while if the opponents keep pushing the wave while you only last hit the opponents can be vulnerable to ganks depending on their vision control and position.

Keep in mind that Kai'Sa has a pretty low autoattack range so most of the time you'll get poked down in lane while not being able to respond to it. However, you have a surprising amount of burst with your Plasma proc's. Combined with Press the Attack you can potentially score a kill onto the opposing laners if they underestimate you/you catch them off-guard. If your support can CC a target down that gives you the opportunity to stack your Plasma on them and boom, you won a trade.

After laning phase is over, you should be most of the time grouping with your team. Alone you can't really fight most assassins/bruisers unless you are miles ahead of them in gold/exp and even then potentially not. You and your team should try to take down objectives (towers, dragon , Baron if favorable) to gain gold advantage and work towards the victory.

Also remember to keep clearing sidelane waves when you and your team aren't looking to take down objectives/teamfight since you should always look to do something valuable where you can gain gold/exp from.

When the teamfights arrive, you'll most of the time want to stay further back, but since Kai'Sa doesn't have really that long attack-range that often isn't possible. Main targets are usually opposing carries but going for them straight away often can put you at risk. You as an ADC are one of the main sources of damage for your team, and if you die in a teamfight straight away that cuts your teams damage down quite a lot. Most of the time you should try to focus down the targets that are most near to you, since they are the most dangerous to you at that moment.

Kai'Sa's Killer Instinct allows you to reposition near a target that has been applied with Plasma recently, this can allow you to quickly dash in to take out a squishy target for example, and then reposition with your Supercharge (especially once you've upgraded it to have stealth).

When opponents have assassins on their team, you should most of the time wait out till they show up and focus someone else since they'll likely just delete you in under one second and boom, you did nothing in a teamfight. Leave handling the assassins for your team and keep yourself alive so you can deal damage on the rest of the opposing team.

Kai'Sa's Void Seeker can be a great way to scout out unwarded territory/objectives like Dragon and Baron to see if the enemies are taking them.
Back to Top
Kai'Sa is a very diverse champion, who can be played in multiple roles with different playstyles and builds. She offers burst damage and can quickly jump in fights with her Killer Instinct, which can sometimes turn the fights.

Any feedback on this guide is highly appriciated, I will be updating this constantly whenever I have time and I learn more about Kai'Sa.

Have a great time hunting voidborns and non-voidborns as Kai'Sa!
