Updated on June 20, 2026 at 10:36am: Added detailed patch notes. Kindred was removed from champion buffs.
League of Legends Lead Gameplay Designer Matt “Riot Phroxzon” Leung-Harrison posted a preview of the LoL patch 26.13 notes on X on June 16, 2026 and a detailed breakdown the day after.
As this is the patch MSI will be played on, LoL patch 26.13 primarily focuses on champion balance changes.
Riot Phroxzon also shared a brief update on the upcoming release of Locke. The team is excited for his debut, noting that both internal playtests and community reactions have generated plenty of enthusiasm so far.
“Currently, we’re trying to lock down a few tunings and timings on some of his abilities as well as where we want his power budget and maxes to be, a process called fine tuning,” Riot Phroxzon wrote.
“A lot is changing day by day, in particular, the amount of power budget in his W has been something we’re trying to fine tune as well as how Normal versus Elite skewed he is,” he added.
LoL patch 26.13 notes
Rather than introducing major meta shifts, this patch focuses on improving a few underused champions, making them more appealing as situational picks that teams can turn to as the MSI tournament reaches its final rounds.

LeBlanc
LeBlanc is being helped to scale slightly better into the mid and late game through this set of changes. As these buffs improve scaling, they are expected to disproportionately benefit Solo Queue.
Olaf
Olaf jungle is not being significantly buffed, as he is already flex viable in top lane, but the goal is to make his jungle role more viable, as it was his original primary position.
A targeted buff to his Q is being made to improve his clear speed, especially in the later stages of the game.

| Sion | W Mana: 65–85 → 75–95 Q Min Damage: 40–120 → 30–90 (max damage unchanged) |
Bard
Bard is currently at the top of the meta in both professional play and many Solo Queue skill brackets.
Adjustments are focused on reducing damage output across his builds, particularly since tank roaming setups are dealing more damage than intended.
Brand
Brand changes are primarily targeted at his bot carry tuning, while also affecting his support and mid roles to a lesser extent.
That said, Brand support is often a frustrating experience for bot laners, and he should also sit a little lower in power more sustainably.
Given that Brand support synergizes better with mana regeneration, compensation is being made through this avenue while adding some mana pressure for roles that rely more heavily on frequent E usage.
Cassiopeia
For Cassiopeia, the aim is to retain her identity of strong early all-in pressure, as this adds texture to the roster and remains one of her unique strengths among mages.
Her durability is being targeted in the mid-game, where she is more vulnerable, especially in skirmishes or when playing in the sidelane.
This preserves her core strengths while creating clearer windows of counterplay, Riot Phroxzon explained.
Senna
According to Riot Phroxzon, Senna is the biggest winner of the Season 2 changes, synergizing strongly with Doran’s Helm (gaining substantial effective health from her Q heal scaling with resistances) as well as benefiting heavily from Jack of All Trades’ stat stacking.
She also interacts well with Statikk Shiv on-hit effects, though the interaction (Q cooldown reduction on-hit) is not being supported despite being a fun mechanic.
Given all of this, she appears to be dealing a bit too much damage relative to her level of durability, and Riot is therefore nerfing her.
System buffs
| LOL PATCH 26.13 SYSTEM BUFFS | PATCH NOTES |
| Imperial Mandate | Build Path: Blasting Wand + Bandleglass + 650g → 2× Amp Tome + Bandleglass + 700g AP: 65 → 60 Unique Passive – Control: +15 AH on immobilizing abilities → +20 AH Unique Passive – Command: 6% Vulnerable on immobilizing → 7% Vulnerable |
For system changes, Riot is making another round of adjustments to Imperial Mandate. While previous updates have expanded its user base, the item has seen more adoption from champions such as Galio, Twisted Fate, and Lissandra than from the support champions it was originally designed for.
With this patch, the goal is to push Imperial Mandate closer to its intended support-focused identity while also increasing its overall power.
Riot noted that, despite having strong synergy with many support kits, the item currently isn’t considered the best choice on most of its intended users, something the team believes should change if the item is tuned appropriately.
System nerfs
| LOL PATCH 26.13 SYSTEM NERFS | PATCH NOTES |
| Doran’s Helm | Health: 140 → 150 Armor & Magic Resist: 10 → 8 |
Doran’s Helm has recently started seeing situational use on a few ADCs, particularly those that benefit from its resistances and sustain.
Senna is a notable example, where her healing pairs well with the added effective health, while Jhin can also take advantage of it given how much of his early damage relies on base values.
The goal is to preserve these niche incentives, Riot Phroxzon explained, but bring the item more in line balance-wise for those users, while also opening it up to a slightly wider set of viable champions as a result.
