Power vs. the roster

Share of the roster this champion outclasses, at each stage of the game.

Early (lv 1-5)2 %
Mid (lv 6-10)9 %
Late (lv 11-15)91 %
Scales into the late game– – roster average
Lv 6 Guinsoo's RagebladeLv 9 Navori QuickbladesLv 11 Terminus

50% = average for the roster at that point of the game, 90% = among the strongest. The three phases come from the site's editorial tempo grid (early/mid/late, rated across 142 champions); the level-by-level curve adds this build's computed spikes — ultimate, completed items — never by more than ±8 points.
