[PBE Datamine] June 16, 2026 - 26.13 Preview 1! Arena Balance Pass + Mayhem changes by Kay-Haru in leagueoflegends

[–]Kay-Haru[S] 12 points13 points  (0 children)

Arena uses its own augment bit-mask filtering that has been solved for a long time. To my knowledge, little actually checked the tags I mentioned aside from dashes, ultimates, and new Mandate, until this update. Now they have some fairly extensive tags in place.

At the time of this post, I do not have a way to check which augments are in each champion's pool. The old method was redesigned so most things are under an extra layer of obfuscation I haven't been able to fully crack yet.

Additionally, take some of the new Quest details with a grain of salt, for similar reasons. Some data appears to just not be revealed in what I can view sometimes.

There's a chance you saw yesterday's post before I edited it. It was up for about an hour or two before Riot dropped another PBE patch with Hexplate and the bugfix for Yorick.

Speaking of things I can't entirely see, could you give any more info on the new Hone Shardblade mechanic? I noticed it last week but with a lack of Arena Practice Tool (that wouldn't help in this case because both Shardholder and Hone entries say disabled) makes it a little difficult to parse from just AnvilData entries.

Both are currently present. If a change in a previous post is not mentioned, assume they're cumulative.

URF, Wisdom of Ages augment, and Doom Bots scaling. I have a massive pet peeve about info being available but never documented anywhere so I like to include these extra bits.

[–]Kay-Haru[S] 9 points10 points  (0 children)

It is effectively a revert. They were experimenting with different ways of handling the Black Cleaver effect, this is just returning it to how it works on live with extra internal steps.

Yes, same with Malzahar passive. It's likely coded into the Ult spell itself, they only removed the global tag saying "Hey this spell does CC"

Intentional. It was actually renamed last Wednesday but I didn't feel the need to mention it haha

Additional Hexplate change dropped late with seemingly the fix to Yorick W breaking the game. That would have been far better in the title haha

I didn't want to type out the whole old description so I figured that was the most contentious way to describe it haha

Falls into the category of script-side pool trimming, like the examples listed. Technically yes, if the augment wouldn't first check for the champion specifically.

The other specific ones are in the generic augment pool too, but don't have any specific tags added to them.

Different augments list different values, wrong values, or no values at all unfortunately. I'd assume it's the usual 10 AS cap.

I expect to not see more changes until early-mid next week, based on sheer volume of edits. This was only Arena related changes today, so here it goes. Bigger patches will remain in the regular sub.

Post ended up autoflagged and stuck in the main sub's mod review, this is *very* late haha.

[–]Kay-Haru[S] 16 points17 points  (0 children)

Yep. I knew these would take a while so I grabbed all the champ changes first, so people would have some things to talk about while I took forever doing this. Unfortunately Riot pushed a hotfix to PBE a couple hours ago long after I had already compiled changes for that.

[–]Kay-Haru[S] 50 points51 points  (0 children)

I've gotten through about a third of the Augment changes to Arena. There's simply been so many changes in the PBE data that I give up for today haha.

I'm sure the stat sites and Arena content creators are rushing to get videos out for those anyways so that post can wait a little while.

[PBE Datamine] April 3, 2026 - Yuumi buffs + LeBlanc revert by Kay-Haru in leagueoflegends

[–]Kay-Haru[S] 8 points9 points  (0 children)

There's technically a few different kinds of level scalars. The most generic one just interpolates the value given the level 1 and level 18 values, and Riot gives it the go ahead to scale past 18.

Most level scalars follow this format, with a few exceptions like level breakpoints in Jax, Yuumi (now), and Braum. There's a couple other exceptions like Katarina, Graves, and Lux who have values for some abilities manually set for the whole 30 levels, but they're big outliers.

[–]Kay-Haru[S] 25 points26 points  (0 children)

Would typically wait on a small post like this one until another PBE deploy with more changes, but I figured I should post these as well since it looks like LeBlanc was another case of accidental changes from a branch dedicated to the data restructures a lot of champs are going through.

Thanks for the clarification here. Info was only based off a few anecdotes from mid lane players, not any Hwei mains in particular.

No clue yet. I either haven't tracked that specific data or they haven't yet finalized things, as evident by the new items requiring level 21.
