League of Legends Patch 9.10 is now available on the PBE. While balance changes don't seem too severe at the moment (which is unsurprising after the number of tweaks in patch 9.9), the next update does herald a major change in the form of new champion Yuumi.
The magical (and adorable) cat will arrive on the Rift this patch, and promises to shake things up a bit. The whimsical support comes with the ability to permanently attach to an allied champion, becoming almost completely untargetable, but losing the ability to move around. Riot reckons she'll be a good fit for new players getting to grips with the game, but it'll be interesting to see what she can do in the hands of League of Legends veterans.
Elsewhere, Yuumi helps bring in a brand-new skin line. Ezreal, Graves, Lux, Katarina, and Jayce join her in the new Battle Academia cosmetic set, which returns League of Legends to the same anime stylings that players have enjoyed with skin lines like the Star Guardians.
