The League Worlds will be played on patch 26.20, so the new update is one of the last ones before the major event.
League of Legends Patch 26.18 is not the final Worlds patch, but it is one of the first clear steps toward the tournament meta. According to Matthew “Phroxzon” Leung-Harrison, Lead Gameplay Designer for League of Legends, this update is mainly about targeted adjustments rather than massive changes. Cassiopeia is being rebalanced and Master Yi and Rageblade are getting some power back, while Seraphine, Zeri and Syndra are among the champions being nerfed. The patch is expected to release on September 10.
Cassiopeia Is Being Rebalanced Between Pro Play and Solo Queue
The most interesting champion in Patch 26.18 is Cassiopeia. Riot currently sees her in a difficult position: she is struggling for average players but too strong in Elite play and Pro Play. Champions like that are especially difficult for balance teams, because a simple buff can immediately become a problem at the professional level.
That is why Riot is not going for a classic buff but a power shift. Cassiopeia’s early base damage is being reduced, while more power is moved into her AP ratios. The reasoning makes sense: according to Phroxzon, average players tend to buy more AP, while pros are better at abusing Cassiopeia’s strong laning phase and system synergies.
Her Q interaction with Deathfire Touch is also part of the issue. Riot does not want to remove her early-game identity completely but wants to stop her from winning lanes too reliably, even when everything is not played perfectly. Cassiopeia should remain a strong early-game champion but feel fairer across different skill brackets.
Seraphine and Zeri Are Being Targeted
Seraphine remains one of the hardest balance problems in the game. She is played support, mid and bot, but not every role uses her abilities the same way. Riot therefore wants to weaken her E rank-up incentives for damage-oriented roles. Support Seraphine should be less affected, because she usually maxes E later.
That fits Riot’s direction over the past few months. Mage bot is not supposed to disappear entirely, but certain versions should become less dominant or frustrating. Seraphine is especially difficult because she is at the same time a popular support, a strong farming pick and a recurring frustration point.
Zeri is also being nerfed. The reason is not that Hurricane itself is being rolled back. According to Phroxzon, Riot is generally happy with the Hurricane changes because the item feels real again. Zeri, however, benefited too much from them, especially in higher skill brackets. Riot is following a clear principle here: first get items into a good place, then adjust the champions that gain too much power from them.
Ekko, Viego and Zaahen Get Specific Help
On the buff side, Ekko is interesting because Riot is specifically targeting mid lane. He gets more waveclear and better mana values, making his roaming and tempo game plan more reliable. That is a deliberate choice: more waveclear can make laning less interactive, but for a champion like Ekko, being able to control waves and then look for plays on the map matters a lot.
Viego is getting support for his bruiser build. After the removal of Divine Sunderer and the nerfs to Sundered Sky, bruiser Viego became weaker than squishier versions. That is intended in principle, but Riot seems to think the build landed a bit too weak and is giving it more explicit support.
Zaahen, meanwhile, is receiving more of a clean-up change. After the last round of nerfs, he ended up slightly weak, and Riot is also making his Q behavior after reviving more consistent. Before, he could apparently end up in desynced states where Q2 only had a very short window to be used after coming back.
Master Yi Also Benefits From the Rageblade Fix
Master Yi is one of the champions most affected by the Rageblade issue. In Patch 26.14, Guinsoo’s Rageblade was re-scripted, which changed the Phantom Hit trigger from six to seven attacks. Riot now wants to give some power back to the item itself and to champions that were disproportionately affected. Current preview values include an increase to Rageblade’s stack duration.
That also explains why Master Yi stands out in this patch. He is a champion who depends heavily on on-hit systems. If Rageblade becomes less reliable or slower, Yi feels that much more than many other users. Patch 26.18 therefore does not feel like a pure Yi buff but more like a correction to a system that hit certain champions too hard.
26.18 Is Small, But Important for the Worlds Direction
Alongside Cassiopeia, Seraphine, Zeri, Ekko, Viego, Zaahen and Master Yi, the patch also includes buffs for Kassadin as well as nerfs for Bard, Nautilus, Syndra and Zeri. Overall, though, 26.18 does not look like a patch that wants to rebuild the meta completely. Instead, Riot is correcting individual outliers and trying to close problematic gaps between Pro Play and Solo Queue.
That is exactly what makes the patch interesting. Before Worlds, Riot rarely wants chaotic massive changes, but small adjustments can still have major consequences. If Cassiopeia becomes less lane-dominant, Zeri is more controlled after Hurricane, and Rageblade users like Master Yi land in a healthier spot, 26.18 could already show which direction Riot wants to take for the final patches before Worlds.
