League of Legends – 9.12 Patch Notes

Patch Highlights

Balance Framework

Last week, developers introduced the Champion Balance Framework, a source for all players to hold the “balance” team accountable for how we approach buffing/nerfing champions on a patch-to-patch basis. Moving forward, we’ll be referencing principles, thresholds, and specific audiences from the post when explaining the changes in the Patch Notes. For more details and information, you can find the full Champion Balance Framework post here.



The Iron Revenant

The unstoppable juggernaut is back from the afterworld and ready to conquer the land of the living in patch 9.12!


Q spell ranks decreased, shield removed, damage bonus now dependent on R. W now slows; Spell Flux bonus converts slow to root.

When Ryze is played optimally, he covers his weaknesses incredibly well. At the same time, he benefits highly from a coordinated team. Pro play relishes champions with these characteristics, which is why he’s been such a strong pick in the space. We’re chipping away at these strengths to quell his presence there, but at the same time, helping out those who are looking to pick him up and aren’t as precise in their combos.

With the removal of his shield, he’ll have fewer means of survivability against bad match-ups, and by changing his CC to a slow, his gank targets should have better chances of escaping a 2v1 (especially a Flash > Rune Prison combo). As part of the general adjustments we’re making to make him more welcoming to less experienced players, we’re also opening up the bouncing game a bit more by making Spell Flux always bounce off its primary target, and placing some scaling into a passive on Realm Warp. Then there’s a bunch of tuning to account for those changes. It’s not what we would typically call a rework, but since it’s Ryze, we’ll count it. Looking forward to v7 (v8?)!
