Real versions of this comp's final board: which exact group of champions shows up together, how often, and the average placement of those games. Not a game-by-game history (Riot only exposes the end-of-game board, never how it got there): a comparison of builds, not a timeline.

Board add-ons (9th/10th unit)

Base board — 9 units 3.32 avg placement · 31 games

+1 unit (10 total)

Lux 1.25 avg placement · 4 games

The main board above stops at 9 units: reaching a 10th slot needs level 10, which on its own already correlates strongly with a good placement. Below, the average placement of games with this base board plus one or two extra units, shown as a correlation to interpret, not a causal recommendation.

Augment path

Data unavailable. Riot's API doesn't populate the augments field for this set — verified directly on the collected sample (the "augments" field doesn't even appear in the response, across 23,000+ real participants checked). The field does exist in the official schema and worked on older sets, so this probably isn't permanent — this section will activate automatically as soon as it fills in again.
