How these rows are made

Level 7 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.

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.
