For Katarina, the League of Legends champion, the best choice for patch 26.18 according to community data from u.gg and mobalytics is a rune page built around the Electrocute keystone from the Domination tree, together with Sudden Impact, Grisly Mementos and Relentless Hunter, with Precision as the secondary tree running Coup de Grace and Triumph. This is a summary of what currently gets played and wins the most at higher ELO, not an official recommendation from Riot, so the numbers and the rune order will shift with future patches. How the rune system works in general is covered in the article on runes in LoL. This one goes straight to what to pick specifically for Katarina in League of Legends and why it suits her, even though her numbers change so often between patches.
Recommended rune page for Katarina
The currently most successful combination for mid:
- Primary tree, Domination: Electrocute (keystone), Sudden Impact, Grisly Mementos, Relentless Hunter.
- Secondary tree, Precision: Coup de Grace, Triumph.
- Stat shards: adaptive force in both offensive slots, health in the defensive slot.
Katarina has long been one of the champions whose recommended page changes less than most. Electrocute as her keystone has suited her through practically the entire history of Runes Reforged.
Why this combination suits Katarina
Katarina is a high-risk assassin built around one central mechanic, her passive Voracity. Whenever she secures a kill within three seconds of damaging the enemy, her remaining cooldowns are reduced by fifteen seconds. That makes her a champion who, after the first successful hit, can chain one takedown after another until she runs out of enemies or dies herself. Bouncing Blade throws a dagger that bounces between targets, Shunpo teleports her to any target, including her own dagger stuck in the ground, and picking the daggers back up recharges Shunpo even faster. Her ultimate, Death Lotus, channels a shower of daggers onto nearby enemies with a grievous wounds effect and reduced resistance to crowd control. Her rune page has to support exactly this principle: the faster and more reliably she secures the first kill, the faster she gets her tools back for the next one.
Electrocute does exactly that. Three hits on the same target in a short time unlock a one-off burst of extra damage, which often decides whether the enemy survives or drops into range of her passive. Sudden Impact adds damage after a dash, which for Katarina means after every Shunpo, so practically in every engagement. Grisly Mementos increases maximum health and grants extra damage when she uses her dagger abilities effectively, and Relentless Hunter speeds her up out of combat, so she reaches the next target faster once the first one falls. That is exactly the moment when Voracity pays back the most for the risk she took going into the fight.
The secondary Precision tree handles a different side of the problem: surviving and finishing the combo. Coup de Grace adds damage against low-health enemies, which comes in handy right when she is finishing the kill her whole passive depends on. Triumph restores health and gold on takedown, which helps Katarina survive the very next trade. She is an extremely fragile champion with no shield of her own, so this small bit of healing often makes the difference between continuing the kill chain and having to back off.
The stat shards then just fill in what the primary and secondary trees don’t cover. Adaptive force in both offensive slots increases the ability damage Katarina needs to reliably trigger Electrocute, and health in the defensive slot compensates for her complete lack of any shield or heal outside of Triumph. Given how quickly Katarina can die when a combo fails, the defensive shard is almost always a better choice than another offensive one.
Variations by situation
Against heavy crowd control
Katarina has no crowd control resistance of her own apart from what her ultimate gives her for a limited time. Against compositions with several hard CC abilities, it pays to add a shard or rune for resistance to slows and immobilizing effects, because getting caught once in the middle of a combo can shut it down entirely.
Against immobile targets
Against enemies without a dash or blink, Katarina is especially dangerous, because they can’t escape Shunpo or her dagger pickups. Here it pays to go fully offensive, including adaptive force in both free shard slots.
Katarina in teamfights vs. solo kill attempts
In teamfights, where Katarina acts more as a finisher than an initiator, Coup de Grace makes even more sense than in a 1v1 in lane. The goal is to finish off weakened targets quickly and trigger Voracity as early as possible, not to take a long fight against a single opponent.
Against an aggressive jungler
If you are facing pressure from the enemy jungler from the early levels, it pays to lean the defensive shard a bit more toward health and play more carefully until you have enough levels for Death Lotus to decide a fight on its own.
Katarina against a healing composition
Against enemies with strong healing, whether from their own kit or from items, consider a secondary keystone or rune tied to grievous wounds outside of your ultimate. Death Lotus only reduces healing while it is channeling, so an additional source of grievous wounds helps keep the effect up outside the ultimate too.
What to avoid
- Overly aggressive play without a secured kill. Katarina’s rune page is built on her securing the first kill. If she enters a fight without being sure she can finish it, she gets no reset from Voracity and is left extremely vulnerable in the middle of the enemy team.
- Skipping Triumph in the secondary tree. Without the health restored on takedown, Katarina often doesn’t survive the very next trade, even after successfully securing the first kill.
- A secondary tree other than Precision without a good reason. Alternatives like Sorcery give a bit more damage, but they take away the survivability that Coup de Grace and Triumph give Katarina. For such a fragile champion, that is a risky trade.
- The same page no matter how much CC the enemy has. Without any crowd control resistance, Katarina is extremely vulnerable against compositions with two or more hard CC champions. Ignoring that and going fully offensive is usually a mistake.
FAQ
For patch 26.18, community data points to Electrocute from the Domination tree. Three quick hits on the same target match exactly how Katarina opens a fight with her Bouncing Blade and Shunpo combo.
Because her main problem isn’t a lack of damage but surviving between kills. Coup de Grace and Triumph help her finish off weakened targets and recover right after the first takedown.
Voracity reduces her cooldowns by fifteen seconds on a takedown within three seconds of damaging the target, so runes that help her secure the first kill quickly and reliably, like Electrocute, are worth more than usual on Katarina.
No, it’s purely a shared name. This article is only about Katarina, the League of Legends champion, and her rune build, and has nothing to do with the name as such.
Not really. She is a mechanically demanding, high-risk champion. The rune page suits her well, but without a mastered combo and good in-fight decisions, the advantage of the runes goes to waste.
Most often adaptive force in both offensive slots and health in the defensive slot. Given how fragile Katarina is and how quickly she can die after a failed combo, the defensive shard is almost always worth it.
