League of Legends patch 13.15 notes: Kai’sa & Ivern nerfs, Yasuo & Yone buffs

League of Legends patch 13.15 is right around the corner, and with it comes nerfs to champions Kai’sa and Ivern, buffs to the brothers Yone and Yasuo, and several other key adjustments to keep the game healthy.

A new patch for League of Legends is on the horizon. Patch 13.15 will bring more balance changes to the popular MOBA with the devs hoping to address some problematic champions of late.

While this patch doesn’t have any massive changes like those contained within the recent ADC item rework, it looks to take some of the problem children of recent patches down a peg while giving underperforming champions a bit of a boost.

When does LoL Patch 13.15 go live?

League of Legends Patch 13.15 is expected to go live on August 2nd, 2023, according to Riot’s patch schedule. Patch 13.15 will head to Oceanic servers first, with other servers slowly receiving it throughout the day.

Here are the key timings of Patch 13.15 for your server:

• 3 AM PT (NA)
• 5 AM GMT (EUW)
• 3 AM CET (EUNE)
• 8 AM KST (Korea)

There’ll be a few hours of downtime when patching begins, and matchmaking queues will be taken offline about three hours beforehand.

What’s changing in LoL Patch 13.15?

Riot Games

Kai’sa and Ivern nerfs

Kai’sa and Ivern have become strong contenders in the meta, with Kai’sa’s AP build dominating professional play. Ivern’s had a similar level of success in high level play, though the people who main this champion aren’t too happy with the state he’s in on patch 13.14. Perhaps the new slew of changes will change their mind.

Yasuo and Yone buffs

Both Yasuo and Yone have struggled a bit after the ADC mythic item rework that saw their itemization change. The brothers have been in need of a bit of a touch-up, and Riot is planning on giving them some love in the coming patch.

Reduced pet durability

Ivern, Annie, Heimerdinger, and Yorick are all getting some changes this patch. While Yorick’s got some buffs to his Maiden incoming, all of these champions are having their pets’ durability hit. However, there’s also a massive nerf hitting Smite’s effectiveness against pets to even out the nerf.

Q: Shattering Strike

• Q now maintains its absolute direction after flashing rather than its original target

W: Ferromancy – Mount Up

Yasuo

Passive: Way of the Wanderer

• Base shield now uses non-linear level scaling (+30 at level 3, +75 at level 6, +125 at level 9, +79 at level 16) The idea here is to give Yasuo a stronger shield in the mid game to counteract Shieldbow’s semi-recent move away from being a Mythic item.
