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. Rows marked real are the boards of the games that went out at that level holding four or more of this comp’s units — real boards on the way to it, not its own games. 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.
