2XKO Patch 1.2.3 Meta Guide: Ahri Nerfs, Senna & Thresh, and The Climb PvE Explained

2XKO Patch 1.2.3 dropped on June 9, 2026, and it’s the biggest update Riot has shipped for the tag fighter yet. Two new champions—Senna and Thresh—land alongside a full roguelike PvE mode called The Climb, a ground-up rework of the Teamfight Fuse, and hard nerfs to two of the most complained-about characters: Ahri and Teemo. With EVO 2026 just a few weeks away, the 2XKO Patch 1.2.3 meta is already a heated topic. This guide breaks down every meaningful change, gives you actionable counterplay, and hints at where the tier list might settle.

Ahri Nerfs: What Changed and How to Punish

According to the 2XKO patch notes June 2026, Ahri’s aerial dominance took a real hit. The standout change is her midair S1 fireball: it now has 11 extra recovery frames on whiff. That’s a huge window. If you see an Ahri player fishing for a jump-in fireball and they miss, you can dash in and start your combo before she can block. Her air normals also lost blockstun: Air M went from 16 to 15 frames, Air H from 20 to 18, and Air Down H from 20 to 17. Combined with the fact that her Air J2 sequences are no longer true blockstrings, Ahri can’t lock you down in the air the way she used to.

Her damage got shaved too. Upward Spirit Rush damage is lower, and the second hit of her held S1 super now scales at 45% instead of 66%. A larger back hurtbox and slower midair Down M/Sweep recovery make her easier to swat out of the air. One high-level Ahri player on Reddit put it perfectly: “Most of her play at the top level stays the same, but some two-touch scenarios drop to three-touch.” She’s still dangerous, just not deleting you off a stray air-to-air.

“One high‑level Ahri player on Reddit summed it up accurately: most of her play at the top level stays the same, but some two‑touch scenarios drop to three‑touch.”

How to exploit the new Ahri: immediately after she whiffs a midair fireball, use a fast-button to punish. Push-block her air normals to reset neutral—she no longer has the frame advantage to force a mix. If she tries to air blockstring you, mash a quick air jab; you’ll interrupt her. Champions with strong anti-airs like Illaoi and Darius can stuff her approaches more reliably now.

Teemo Nerfs (and the One Thing That Survived)

Teemo’s toolkit got sanded down in several spots. His Forward S1 has slower knockdown speed when hitting low opponents, and his Midair Down H hitbox—while expanded—loses OTG properties, so you can’t pick up a grounded opponent as easily. S2 (the roll that sets up overheads) has reduced blockstun, and both midair darts and back assist have larger hurtboxes, making him more vulnerable to pokes. Jump M’s hitbox is smaller, and the damage on his Midair Down M first hit and charge‑to‑H is reduced.

But the community’s biggest headache—the instant-overhead setup with Mushroom Super—went completely untouched. That sequence, where Teemo calls mushroom and immediately goes for an overhead, remains one of the most suffocating mix‑ups in the game. Many players expected Riot to nerf it here, and they didn’t.

“What did not get touched: the Overhead with mushroom super. That specific sequence … is widely considered one of the most frustrating things to deal with in the game right now. The community expected Riot to address it here. They did not.”

Still, the nerfs give you better windows. Teemo’s S2 is less plus on block, so you can backdash or counter‑poke more often after the overhead attempt. The larger hurtboxes on his assist and darts mean you can stick out a long-range normal (like Ekko’s bat or Yasuo’s sword) and catch him before he starts his shenanigans. If you have a character with a low-profile move, use it to go under his initial dart and punish the roll startup. He’s not free, but he’s far from untouchable now.

New Champions: Senna and Thresh Overview

This 2XKO Senna Thresh guide gives you the fast facts on both newcomers. Senna is a dual‑form spacer. In her base form she wields a relic cannon that fires delayed, wide‑angle projectiles—great for controlling space and forcing opponents to respect her range. Activating her super (“Wraith Form”) shifts her into a rushdown monster with a multi‑directional air dash and mix‑up pressure. Wraith Form drains over time, and she reverts to base form once she touches the ground. Expect players to use base form to chip away and build meter, then pop super to go in with ambiguous left/right air dash setups.

Thresh is a zoning trickster whose main tool is a long‑range chain. The chain hits at odd angles that can catch opponents off‑guard, and he can teleport to a thrown lantern that leaves a summoned soul behind. His real killer app is the Lantern Tag: instead of tagging in your partner from the side of the screen, the partner comes in directly at the lantern’s location. This opens up all kinds of dirty cross‑ups, sandwich pressure, and unexpected resets. Early lab monsters are already calling him a top-tier support/point hybrid.

You can unlock both Senna and Thresh for free right now via a shared Champion Recruitment Event that runs for four weeks—about 50% longer than a normal recruitment, since there are two champions. Just complete event missions, and you’ll add them to your roster without spending any KO Points or Champion Tokens. After the event, they’ll cost 10,000 Credits each.

The Climb PvE Mode: How It Works and Rewards

The Climb is 2XKO’s first real PvE mode, and it’s a roguelike. You pick a champion and a Fuse, then fight a series of increasingly tough CPU opponents in single‑round matches. After each victory, you choose from randomized augments—some universal, others tied to your specific champion. Health, Break, and Super meters carry over between fights, so resource management matters. Campfire stops let you heal, but you’ll have to decide whether to spend a stop early or push your luck.

The final boss at the summit is a super-augmented opponent that can feel like fighting a player with cheat codes. Lose at any point, and your run ends. You can play The Climb solo or in online co‑op as a duo—there’s no local split‑screen couch co‑op, unfortunately. Rewards include base chromas for your champions, avatar items, stickers, and Battle Pass XP. It’s a fun, low-stakes way to learn new characters or just blow off steam.

The New Teamfight Fuse and Its Impact

Riot completely redesigned the Teamfight Fuse, and it’s now a double‑edged sword. Duration scales with meter: spending 2 bars gives you 5 seconds of Teamfight, 4 bars gives 10 seconds, and 6 bars gives 15 seconds, with a cap of 3 bars per character. Recovery on activation increased from 5 to 12 frames, so it’s more punishable if you whiff. Two new counterplay options are huge: hitting a Teamfighting opponent reduces the remaining duration by 2.5×, and if you successfully parry the Teamfighter, the Fuse ends immediately. Teamfighters can no longer block or parry a Break activation, so a well‑timed Break is a guaranteed punish.

These changes are shaking up the 2XKO Patch 1.2.3 meta, pushing players to reconsider their Fuse choices. Teamfight is no longer a universal “I’m better” button, and Fuses like Double Down may see more play. The patch notes hint that alternative Fuses could now become the norm.

2XKO Patch 1.2.3 Meta: Tier List Predictions

While the 2XKO 1.2.3 tier list is still being voted on, early sentiment points to Illaoi and Akali rising to the top. Illaoi received no nerfs at all, and she’s been consistently strong across multiple patches. Akali’s only scaling adjustments are proportional, leaving her untouched relative to the rest of the cast. Meanwhile, Ahri and Teemo were the headline nerfs, so the stage is set for those two to dominate.

“Illaoi got nothing. Not a single balance change. For a character that has been consistently top‑tier across every patch … that is a decision that will keep conversations going in the community.”

— Gamer.org analysis

The EventHubs community tier list currently shows every character tied at a score of 60, with zero movement day‑over‑day, because not enough votes have been cast to create a meaningful spread. That’s normal this early. Give it another week of labbing and online matches, and we’ll see real separation—but the 2XKO Patch 1.2.3 meta already has Illaoi and Akali penciled in at the top by many analysts.

EVO 2026 and Pro Player Outlook

Riot has confirmed that EVO 2026—the biggest 2XKO tournament ever—will be played on Patch 1.2.3. That means every pro is grinding this exact 2XKO Patch 1.2.3 meta. The addition of two new characters this close to the event is spicy; it’s unlikely anyone will have fully optimized Senna and Thresh by bracket time, but wildcard counterpicks could shake things up. The nerfs to Ahri and Teemo—and the untouched state of Illaoi—suggest we’ll see a lot of Illaoi/Darius or Illaoi/Akali shells at the top tables. If you’re aiming to compete or just predict the top 8, start labbing those matchups now.

Playing 2XKO on the Couch? Here’s the Controller Reality

2XKO natively supports controllers on PC, PS5, and Xbox Series X|S right out of the box. No dongles, no drivers, no config files—just plug in and play. That’s fantastic for kicking back on the sofa with a fight stick or gamepad. But there’s a catch: the game has no local split‑screen couch co‑op. The new Climb mode offers online duo play, but you can’t share a single screen with a friend on the same PC. For a title that otherwise feels built for the living room TV, that’s a noticeable gap.

If your PC gaming setup alternates between desk and couch—maybe you grind ranked at the monitor but unwind with a few rounds of The Climb from your TV—you already know the pain of juggling launchers with a mouse and keyboard. 2XKO lives on Riot’s own client, but the other fighters in your rotation (Guilty Gear Strive, Street Fighter 6, Tekken 8, Mortal Kombat 1) are scattered across Steam, Epic, and other storefronts. Jumping between them from the couch still means reaching for a mouse.
