Patch 25.20 will release on Wednesday, October 8th, and it will be the patch that all matches of LoL Worlds 2025 will be played on. In this article, we’ll give you an overview of the LoL Worlds patch, and of the landscape that patches 25.18 through 25.20 are shaping for the World Championship.

Patch 25.20: The LoL Worlds Patch

The Pro Play Changes

This patch finalizes the changes aimed at creating the environment for LoL Worlds. It’s a smaller patch, since the big changes were done on patches 25.18 and 25.19, leaving time to correct matters in case something got overshot.

Here are the changes meant for pro play!

Azir (Nerfed in pro play):

[W] Arise!:
- AP ratio adjusted: 40-60% -> 30-70%
- Targets beyond the first damage ratio reduced: 25-100% (based on levels 1/6/11/16) -> 20-100% (based on levels 8-18)
- Recharge timer increased: 10-6 -> 12-6 seconds
[E] Shifting Sands damage increased: 60-220 (+40% AP) -> 70-230 (+60% AP)

Camille (Buffed):

Armor per level reduced 5 -> 4.5
[W] Tactical Sweep:
- Base damage increased: 50-150 -> 60-160
- Cooldown reduced: 17-11 -> 15-11 seconds

Orianna (Nerfed for her tankier build):

[W] Command: Dissonance damage adjusted: 70-270 (+70% AP) -> 70-230 (+80% AP)

Pantheon (Buffed for jungle):

[Q] Comet Spear monster damage ratio increased: 75% -> 80%

- Clone damage ratio reduced: 35-55% -> 30-50%

Lane Swap Changes

Lane Swap Detector Window ends at 3:00 -> 4:00

Lane swap plagued the League pro play at the beginning of the year, up until Riot added a lane swap detection mechanic to drastically punish a team attempting to put a second non-jungle player top lane before the 3:30 mark. This made the strategy disappear, and the lane swap detector was then pushed back to end at 3:00 instead of 3:30 to be less intrusive overall.

A couple of weeks ago, pro players came up with a new version of the strategy, consisting in swapping the ADC and top laner while respecting the correct player counts per lane, before sending the support to join the ADC at 3:00. This has been done to bail a scaling ADC and/or top laner out of a bad matchup.

For the LoL Worlds patch, the penalty is as such extended up to the 4-minute mark, in order to give the jungler a window to punish a solo laning ADC, and allow the solo top laner to retake control of the wave before the arrival of the enemy support to turn the lane into a 2v1.

This isn’t meant to prevent the possibility of these swaps, but to allow them within stricter boundaries and with better windows for punishment.

The Other Changes

The LoL Worlds patch also brings usual balance changes aimed at solo queue.

Anivia: Q cooldown reduced, E damage increased
Katarina: Base armor increased
Malphite: Base armor increased, E damage increased
Veigar: W ratio increased
Briar: Passive maximum stacks reduced
Volibear: Passive damage ratio reduced, E ratio reduced
Warwick: AD and attack speed per level reduced
Fizz: W and R ratios reduced, base damage increased
Graves: Q base damage increased, ratio reduced

These changes are for the most part unlikely to affect pro play, but you’ll want to keep your eyes on Anivia, Malphite and Veigar. Those have been occasionally brought in as niche picks, and these small nudges can end up bumping them into the spotlight if it raises attention on them.
