LoL patch 2025.S1.2 patch notes: Mel Medarda added, Atakhan & Blue Essence changes, Kayn buffs & more

League of Legends Season 2025 is off to a hectic start, but the developers have been quick about adjusting new map mechanics and hotfixing problems. Patch 15.2 aims to scale back the power of several elements in the new season and bring Mel in.

Mel Medarda was an easy choice to bring into League of Legends from Arcane, with her directly following her mother’s footsteps and making landfall on the rift in this patch.

With the patch set to go live on January 23, Riot has now confirmed exactly what players can expect, with plenty of significant changes to contend with.

Here’s everything we know about LoL patch 2025.S1.2 (aka 15.2).

LoL 2025.S1.2/15.2 patch notes

Atakhan and Feats of Strength changes

Riot Games

Atakhan is getting several changes that should affect how often you see which form, while the rewards for both will also be nerfed. Riot explained their thinking behind the changes as follows:

“Now that we’ve seen a good bit of player data as well as some early pro data, we are making some adjustments to how Atakhan’s Form is determined, as well as a small nerf to Bloody Roses.

“Average players will see slightly more Voracious Atakhan while pro players may actually have a higher chance of seeing Ruinous; and both Voracious and Ruinous rewards will be nerfed, with Voracious being nerfed significantly harder.”

The details behind the changes are as follows:

Threshold

• Threshold in Normal/Ranked Games: Reduced by around 20%
• Threshold in Swiftplay Games: Reduced by around 20%

Points Generation

• Points per Champion Kill: Reduced by a major amount
• Points from Champion Damage: Unchanged
• Points Increase when Alone: 1.85x Melee | 1.65x Ranged = Unchanged
• Swiftplay Points Increase when Alone: 1.85x Melee & 1.65x Ranged > 2x Melee & 1.75x Ranged

Voracious

• Gold granted for triggering the Withdraw effect: 100 Gold > 200 Gold

Bloody Roses

• XP Per Rose: 25 > 23
• Adaptive Force Per Rose: Formula decays slightly faster (Subsequent petals are worth the minimum at 34 rather than 39 stacks)

Blue Essence changes

Riot heard player complaints about the Blue Essence changes, and they listened. This patch, there will be a massive increase in the amount of BE players gain from every part of the Battle Pass.

Changes

• Increasing the total Blue Essence from Milestones from 4750 to 9000 (starting with Act 2)
• Adding a one-time compatible mission for 4250 BE to make up for the difference in Act 1. (Live with this patch, until the end of this Act)
• Increasing Blue Essence from repeatable milestones from 50 to 750 BE. (Live with this patch)

If you’re someone trying to grind for new champions and have already been through the pass, this patch will give you 15 times more currency than before.

While this will alleviate the issues revolving around BE distribution, it still doesn’t make up for the fact that free Hextech Chests were removed. It also has players questioning why all champions aren’t just free to begin with.

Mel Medarda

Mel’s arriving on this patch! You can check out our full ability guide for her to see what she does. That said, if early footage is anything to go off of, she’s going to be very strong.
