Sejuani vs Locke Counter Pick
Matchup Summary
What the Data Means
Frost stacks decide this jungle clash. Sejuani applies them with Winter’s Wrath and cashes them in through Permafrost, so any exchange that runs past a few seconds ends with Locke stunned rather than leaving. The patch 16.13.1 record runs to 554 games and hands Sejuani a 57.4% win rate, graded Easy, a margin wide enough that the shape of the two kits, rather than chance, accounts for it.
Locke leans on Silver Stake, an on-hit magic component that grows with missing health, and on Soul Ignition, which buys attack speed and movement speed by spending his own health. Spending health is the awkward part. His 655 base pool reaches 2,508 at level 18 with 103.4 armor, while Sejuani starts at 630 and finishes at 2,568 with 126.7 armor, so the life he burns is worth more to him than hers is to her. Both run on Mana and both travel at 340 movement speed.
Itemization points the same direction. Locke’s damage is filed as physical, so armor bought against a 34-armor tank pays immediately, while Sejuani’s mixed output denies him one clean resistance purchase. Fury of the North returns armor, magic resistance and slow immunity whenever she has been out of combat, blunting the opening hit of Ashen Pursuit. Locke’s Purgatory can execute a damaged target, so retreating late from a lost skirmish is riskier than never committing to it. Execution ratings read 4 for Sejuani and 5 for Locke.
