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

Riot Games

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 are the full LoL patch 25.09 notes:

LoL patch 25.09 notes

Systems Changes

Lane Swap Detection

Detection still requires there to be a jungler on the team
Detection is still active from 1:30 to 3:00 in top, and 1:30 to 2:15 in mid
Defending champion still receives all gold/xp from the lane, receives 50% less damage while under their tower in top lane, and the defending tower still receives 95% less damage while any two non-junglers are in their lane
Non-supports no longer receive reduced gold and XP from lane minions during lane swap detection
Supports in mid and top lane, when accompanied by another champion, now receive no gold or XP from lane minions and cannot consume World Atlas charges
1000% increased turret damage in the top lane is now locked behind seeing two non-junglers including a support in the lane
