The Yuumi Rework abilities have finally been revealed.

Yuumi, The Magical Cat, is likely one of the most controversial champions in League of Legends. She is frustrating to play against and even with, and frankly, hated by most of the player base. Moreover, she also is a balance nightmare for Riot.

Since her release in 2019, the balance team has been trying to figure out how to balance Yuumi for a long time. They buffed and nerfed Yuumi several times throughout the years. Yet she remained either too strong or completely useless; there was no in-between. Thus, in December 2022, Riot announced they would rework Yuumi. And after months of waiting, the rework is finally here.

Riot Phroxzon, the Lead Designer of the League Balance Team, recently revealed the Yuumi rework on his Twitter page. In it, he explains the goal of the rework and how the changes will ultimately affect her gameplay.

He said, “Yuumi’s untargetability can be frustrating, but we think it’s required for her to succeed on her goals.” So to combat such frustrations, they are introducing the “Freindship” mechanic. Yuumi builds Friendship whenever her ally kills champions and minions while attached to said ally. The more Friendship she has, the stronger her abilities grow.

So, sticking to a single partner is now the most optimal choice. They also make her Q – Prowling Projectile easier to dodge and tie her healing to hitting the ability. Additionally, her ultimate no longer roots.
