Teamfight Tactics patch 18.5 arrived on October 21, 2026, with Riot's rundown published on October 20. Rather than reshaping Set 18, it is a follow-up to the larger changes in patch 18.4.

Riot describes it as a patch of more precise adjustments and buffs to underperforming champions. Here is what that means in practice.

The Philosophy Behind Patch 18.5

Riot says 18.5 makes smaller, more focused changes. Most of them respond to what happened after 18.4, which was a much larger update.

The patch has two main goals:

  • Fix adjustments from 18.4 that did not land as intended.
  • Make AP (ability power) lines viable beyond Azir and Kha'Zix, the two champions that have dominated AP strategies.

In other words, the patch is about balance across the board rather than introducing new mechanics. Players who already know the 18.4 meta will find most of the board familiar, with weaker options getting a better chance to compete.

Why smaller patches matter

After a big patch, balance teams usually watch how players adapt and then trim the rough edges. A strong comp may stay strong in unexpected ways, or a nerf may hit harder than planned. Patch 18.5 is that correction pass, and it is why the changes feel targeted rather than sweeping.

The Blackthorn and Azir Adjustment

The most clearly described change involves Blackthorn. Riot notes that Blackthorn sacrifices were optimized in a previous update, and 18.5 now targets two things: the Blackthorn (6) trait breakpoint and the base AP sacrifice.

The aim is to reduce the power of the strongest comp built around it, which uses a super-charged Azir. A trait breakpoint is the number of units of a trait you need to unlock a bonus tier, so Blackthorn (6) refers to running six units of that trait.

Riot also states that Azir is being nerfed elsewhere. For that reason, the Blackthorn adjustment is intentionally limited. The team does not want to cripple the trait for everyone just to bring down one dominant build.

What this means for players

  • The Azir-centered Blackthorn comp should be less overwhelming than before, but not gone.
  • Other Blackthorn builds should be less affected by the nerf than the top comp.
  • With Azir cut elsewhere too, players may look at alternative AP carries and lines.

Buffs for Underperforming Champions and Where to Check the Meta

Alongside the nerfs, 18.5 includes buffs to champions that were underperforming. The goal ties back to the AP theme: if Azir and Kha'Zix are the only reliable AP choices, the game narrows. Lifting weaker options gives you more routes when your shop or augments do not point toward those two.

Exact numbers are best read from Riot's official patch notes, since they vary per champion and can be tuned on short notice.

As for finding the new meta, community tools update quickly after a patch goes live. TFT Codex, for example, marked its Set 18 comps, tier list, and stats as updated for Patch 18.5 on October 21, 2026. Early tier lists are based on limited data, so expect them to shift over the first few days.

Limitations and What Comes Next

Because 18.5 is a small patch, it will not solve every balance concern. Riot's intentionally limited Blackthorn adjustment shows a cautious approach: nerf gradually, then check the results.

The next patch, 18.6, is listed by community trackers for November 4, so there is a two-week window to see how 18.5 settles. Riot has not been quoted here on any plans beyond this patch, so anything further would be speculation.

Conclusion

Patch 18.5 is a refinement patch. It trims the strongest Azir and Blackthorn build, corrects some 18.4 changes, and gives weaker champions a chance, especially in AP lines.

If you enjoyed climbing with Azir or Kha'Zix, expect a tougher path, and try a few alternative lines while the meta is still unsettled.
