Katarina Wild Rift Best Build Guide

Reset assassin build for chaos punishment: Katarina wins when the first kill or first forced cooldown makes the rest of the fight unreadable. The build must therefore support access, the minimum safety of first commit, and reset continuity.

Power vs. the roster

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

Early (lv 1-5)52 %
Mid (lv 6-10)98 %
Late (lv 11-15)32 %
Peaks in the mid game– – roster average
Lv 3 E rank 1Lv 6 Infinity OrbLv 9 Rabadon's Deathcap + Ultimate rank 2

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.
