the Serpent's Embrace
Patch 26.20 · Stats from the 26.18 Master+ sample (4,088 games).
Cassiopeia, the Serpent's Embrace, poisons with Noxious Blast and feeds on it with Twin Fang, and Miasma grounds enemies so they cannot dash away. Master+ players took her Mid most and Top or in the bot lane less, mostly with Deathfire Touch, and Rod of Ages opened her usual path.

Punish the cooldown — Cassiopeia is exposed while its rotation is down
Ward the flank — vision is what turns its best opening into a worse one
Respect the spike — Riot rates the kit 10/10, so a practised player gets more out of it than the average

Riot's notes from patch 25.S1.1 to 26.20 change Cassiopeia in 8 patches. The latest is patch 26.20, published 2026-10-06.
Base Stats
Our changes two patches ago to Cassiopeia have been pretty good directionally, with most players being proportionally less impacted from those adjustments than pros. We're taking another swing at her early resources because of how dominant she still is in early laning, making her work a little harder to create an advantage.
PSerpentine Grace
QNoxious Blast
ETwin Fang
RPetrifying Gaze
Cassio has always scaled with skill, but this year has propelled her to new heights of pro play dominance despite being weaker for average players. These adjustments should tap down her laning power, especially in pro where defensive purchases are valued more than raw AP, while giving her back some scaling power. It will still be critical to use empowered E's, but raising her floor lets us be a bit more flexible with tuning.
Base Stats
Cassiopeia has risen to the top of pro play presence, even before our 26.12 nerfs to her major competition. We would like to preserve some of her unique strengths, like her rewarding laning and slippery speed, but she should have a less gigantic health bar for when opponents actually lock her down!
Base Stats
ETwin Fang
We're looking to give some mid-favored love to Cass, who hasn't found her… uh… footing in the new season. By bumping up her base mana and empowered E scaling, she should feel a bit more freedom to angle for trades as well as be more rewarded when she finds them.
Base Stats
ETwin Fang
We're looking to get more damage in Cassiopeia's poison this patch, particularly when for her mid lane players. We want to give her more freedom to look for trades and to feel rewarded when she finds successful ones, so we're bumping up her base Mana and empowered E scaling.
Base Stats
PSerpentine Grace
While Cassiopeia's no boots passive is very thematic, the addition of more boot based systems over the years (like role quest rewards) has made it feel like a punishment at times instead of a boon. We think it's important for Cassio to have the opportunity to engage with these new systems so we're reworking the passive into a new movement based effect. (We also wanted to do Soobin a solid.)
Base Stats
ETwin Fang
Cassiopeia has been stagnating in the grass for a while ever since the early few patches of Noxus earlier this year. To help her out we're adding a small buff to her offensive power and early laning by giving her (twin) fangs a bit more bite.
PSerpentine Grace
Cassiopeia is a disproportionate winner in the Feats world, which is probably at least partially due to her lack of feet being a bit overcompensated. Cutting down some of the extra power she gets to make sure slithering isn't too beneficial compared to walking.
Riot's data lists 10 looks for Cassiopeia with their own art, the base skin included and 28 chroma variants.

Riot Data Dragon 16.20.1. Growth curve: League of Legends Wiki — Champion statistic.
Cassiopeia, the Serpent's Embrace, is a Mage champion in League of Legends. Riot rates the kit 10/10 for difficulty, 2/10 for attack, 3/10 for defense and 9/10 for magic. Cassiopeia spends Mana and has 10 skins with their own art. Cassiopeia's base armor of 18 is the lowest of 173 champions on patch 26.20 (shared with 3 others).
Cassiopeia is a deadly creature bent on manipulating others to her sinister will. Youngest and most beautiful daughter of the noble Du Couteau family of Noxus, she ventured deep into the crypts beneath Shurima in search of ancient power. There, she was bitten by a gruesome tomb guardian, whose venom transformed her into a viper-like predator. Cunning and agile, Cassiopeia now slithers under the veil of night, petrifying her enemies with her baleful gaze.
