Renata Glasc Support Build, Runes and Counters · Patch 26.20

the Chem-Baroness

Patch 26.20 · Stats from the 26.18 Master+ sample (1,901 games).

Renata Glasc, the Chem-Baroness, can delay an ally's death with Bailout and turns enemies on their own team with Hostile Takeover. Guardian was the keystone on most counted Master+ Renatas, and Locket of the Iron Solari opened her most-bought path. Alistar, Rell and Janna were her hardest lanes. She held the edge over Thresh and Blitzcrank.

Counter plan — how to beat Renata Glasc

  • Track the roam — it is strongest where the enemy jungler already is

  • Dodge the primary — its rotation is one skillshot; sidestep it and the rest is chip

  • Punish the cooldown — Renata Glasc is exposed while its rotation is down

  • Ward the flank — vision is what turns its best opening into a worse one

  • Respect the spike — Riot rates the kit 8/10, so a practised player gets more out of it than the average

Renata Glasc's story

Renata Glasc rose from the ashes of her childhood home with nothing but her name and her parents' alchemical research. In the decades since, she has become Zaun's wealthiest chem-baron, a business magnate who built her power by tying everyone's interests to her own. Work with her, and be rewarded beyond measure. Work against her, and live to regret it. But everyone comes to her side, eventually.

Methodology

Data window
Preview sample — a one-time snapshot of 65,406 ranked games (Master+, EUW/KR/NA, patch 26.18), counted by GamGem while our Riot production key is under review. Figures will update daily once it is approved. Counted 26–27 Sept 2026; patches 26.18 (35,477) · 26.19 (18,580) · 26.17 (11,048) · 26.16 (293) · 26.15 (8); by server EUW 22,382 · KR 21,922 · NA 21,065 · EUNE 20 · TR 17. 642 games without a result — remakes ended by vote in their first minutes, and games recorded with no winner — were not counted.
Rank aggregation
Master, Grandmaster and Challenger, pooled — the three ladders the count read its players from. Splitting further leaves samples too small to separate a real effect from noise.
Role assignment
A champion is filed under every lane that holds at least a tenth of its counted games — the position the match itself reports, not the champion’s class. Its headline win rate is across all of them; each lane’s own win rate and games are counted too, and a lane’s tier list ranks by them.
Counters
The two champions in the same position on opposite teams, over that pairing’s own counted games — ranked on the edge pulled toward zero by its sample size, printed raw.
Minimum sample
None — no figure is hidden for being thin. Every rate prints its games, and the confidence band is its 95% margin: Very High within ±1.5 points, High ±2.5, Moderate ±3.1 (1,000 games), Low wider.
Why a build is not a cause
An item is counted when the match ENDS with it, so late items show long games and an item bought when already ahead shows games that were being won. Correlation is what a rate can show; it is not evidence that buying the item caused the win.
Where the numbers come from
Names, classes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates, builds, keystones, spells and matchups are counted by GamGem from Riot's ranked match records. An estimate, not a count: this panel is not in the preview sample, and is labelled so.
