How these rows are made

Level 8 and up are the boards this comp’s games ended on. Riot’s match data keeps only that last board, so the levels below are planned by one rule from this comp’s own units and traits and Riot’s shop odds, and marked plan — how the rule works. Hover a trait badge for what it does. Under a measured level, its options: what its games put in the slots past that level’s core, best placed first, with average place, win rate and games beside the level’s own. All of them went out at that level, so none is flattered by having got further. The board draws the first, in a gold ring; the most played is named among them. The row marked best adds the champion that placed best at the level above.

Variationswhat close versions add or leave out, and how they placed

Other boards this comp ends on, over the last 14 days. Each row is a version’s usual final board and what it plays instead of this comp’s own board at that level. A 2 on a portrait: that unit takes two team slots.

Augments that fitby trait and by our rule; no augment has a number of its own

What each augment grants, set against what this comp measured: the same rule the overlay uses when it reads the three on offer. A measured line is the comp’s own placement at a trait level; a line by rule is a fact about the comp, such as the damage its carry is built for.

MeasuredThe comp’s own placement at a trait’s levels, beside the augments that give the trait.

#3.86

Riftbeast 7: averages 3.86 here, against 5.49 at Riftbeast 3 (256 boards)

Riot’s match-v1 data does not report which augments a player took, so no augment has a number of its own on this page or anywhere else on the site. The augment reference lists what each one grants.
