Trundle vs Sejuani Counter Pick

Subjugate into Sejuani is close to the ideal matchup for the spell. She ends at 126.7 armor and 2,568 health, a notably durable build, and Subjugate siphons a share of her health, armor and magic resistance over four seconds, so the bigger her stats, the more it transfers. Much of the 55.1% win rate Trundle posts across 167 games on patch 16.13.1 rests on that one interaction.

Frost Armor changes the plan. Sejuani picks up armor, magic resist and slow immunity after spending time outside combat, so leading with Chomp burns its slow for nothing. Stripping Frost Armor with a basic attack first and committing afterwards is the tidier order. Her damage comes in two forms, Winter’s Wrath and the frost-stack payoff from Permafrost, so neither 37 armor nor 32 magic resist covers the whole trade. Arctic Assault and Glacial Prison both pull her into range, which means the 175-versus-150 range edge rarely settles a fight, and her 340 move speed sits just behind Trundle’s 350 unless Frozen Domain is active. Trundle also starts with more offensive pressure: 68 base attack damage to 66, and 650 base health to 630. Her difficulty rating of 4 against his 5 leaves slightly less room for error on her side. The jungle route that suits him runs through camps where monsters are already falling, since King’s Tribute heals off any nearby unit death, and in a drawn-out fight that sustain, rather than burst, decides it.
