Smaller patch but Halloween Skins and K/DA are now live and available on the client.
This is a slightly smaller patch this time around as we only see a handful of changes made to champions and minor HUD updates. Most unsurprising change is the Kai’Sa nerf as she has been one of the most popular picks for the worlds 2018. However, both of Kai’Sa K/DA skins are now available, one to match with the other 3 female champions that also received K/DA skin, Akali, Evelynn and Ahri, the other is a prestige edition that is limited to only Kai’Sa.
Other skins available in patch 8.21 is the 3 Halloween skins, Bewitched Janna, Trick Or Treat Ekko and finally, Kled receives his first skin with Count Kledula. All 3 skins will also have chromas available to them.
