League of Legends update 25.09 patch notes bring massive objective & system changes

League of Legends patch 25.09 is the biggest update we’ve had in 2025 so far, with the main seasonal theme swapping from Noxus to Ionia and several core game mechanics shifting around. There’s a lot to take in.

Though it’s not quite as big a patch as what you’ll get for each new year, this is meant to be a huge switch-up for League of Legends at all skill levels. Everything from objectives to core systems is changing, and we don’t even know what the champion balance changes are yet.

With the focus being taken away from constant fighting on objectives and early rotations and put more toward proper laning, the way League of Legends will be played has a chance of changing completely with this update.

Here’s what we know so far about the LoL patch 25.09 notes:
