Kai'Sa has been the most picked solo queue ADC in most ranks for months on end, so we're delivering a small nerf to create more variety in the role. The primary nerf is to her base armor, where a bit less early safety should make her feel more assailable.

Kai'sa is intended to be weak early in the game, but her current state is so weak there's not much reason to pick her over other ADCs. We're giving her some breathing room in lane by upping her armor and health regen while also giving her more frequent access to her most exciting tool, her ultimate.

Kai’Sa wound up as one of the big winners from the recent item shakeup and is now a bit too strong. We’re hitting the passive AP ratio slightly and the per-stack plasma damage more meaningfully in order to make her less bound to CC supports and leave crit builds less affected.

We wanted to buff Kai'Sa to encourage more ADC diversity in solo queue and Pro play without touching her AP builds, which can be problematic. We wanted to increase the AD ratio on Kai'Sa's Q to emphasize damage that required higher commitment and played up her unique assassin-like characteristics.

Kai'Sa has been pretty weak this season but has begun to find her footing with Eclipse and Statikk Shiv starts, resulting in a steady climb to her pick and win rates. Even with this newfound tech, we think she's still a little bit underpowered so we're giving her a very small bump to her unique ability to join the fray at a moment's notice.

Kai'Sa is an extremely common marksman in high skill brackets. The fact that she's so frequently blind pickable in high-skilled play has led us to believe she doesn't have enough weaknesses. As a very mobile and strong scaler with incredible build variety (totally reasonable strengths!) she needs to have weaknesses that skilled players can punish. Thus, we're targeting her early laning phase without trying to take away too much of her overall power.

Kai'Sa has skyrocketed in popularity and currently has a wealth of viable build options. Her AD builds like Kraken plus Quickblades are a little too strong and her high-AP ones are quite a bit over the line, which have made her a very powerful bot laner. We're delivering a small nerf to some of her AP outputs, plus a more generic nerf with the hope that she continues to have multiple viable builds and remains fun to play.

As a consequence of the new builds introduced in midseason, Kai'Sa's evolution thresholds now need to be adjusted to better match the items she's opting into. Our goal with these changes is to make her Q evolution feel better. For example, this should grant her Q evolution at level 9 with Stormrazor, Pickaxe, Doran's Blade, and 1 Adaptive instead of having to wait until level 11.

For a marksman that can flex between multiple builds, AP Kai’Sa has been quite weak since her nerfs a few patches ago. We’re giving her AP builds some strength back in a way that won’t lead to her W spamming ways again.

Kai’Sa has been struggling recently, particularly when it comes to her more attack speed or AP-oriented build paths. We’re giving her some scaling power, but in a way that should avoid buffing her problematic full-AP-W-hits-for-half-my-health builds.

AP Kai'Sa today likes to burst her enemies down by spamming W from afar. (Sorry, ARAM players.) We're looking to move her away from that pattern and instead play more around single pops of her passive, which should still feel distinct from her AD builds that usually rely on attack speed and repeated passive procs. This should help all of her stats feel rewarding as well as better align her playstyle with her identity, regardless of how she chooses to adapt.

Kai'Sa represents a hypercarry style that we haven't seen much of in this meta's bully-focused bot lane. Since she's known for her scaling capability, we're buffing exactly that while keeping both her lane vulnerability and Q burst damage intact.

This fearless predator has been making Pro play her prey. We’re looking to draw back some of her early game power by curbing her ability to control waves and giving her opponents more opportunities to punish her when her Q is down.

Kai'Sa's strength lies in striking when the iron's hot: dashing to isolated enemies to burst them down, then sidestepping just as quickly. Her ult adds another level of safety, especially early game, so we're targeting its uptime to give opponents a chance to catch her in lane.

No one adapts to new items like Kai'Sa, and this season proved no exception. We’re reducing some of her damage to lower burstiness and make her less daunting in quick trades early on.
