Quinn vs Sejuani Counter Pick

Sejuani’s kit is built to catch exactly the sort of champion Quinn is, and 139 games on patch 16.13.1 put Quinn at 43.2%. The sample is small, but the mechanics behind it are not complicated.

• Fury of the North gives Frost Armor after time spent out of combat: bonus armor, bonus magic resist and immunity to slows. The slow on Vault is Quinn’s main disengage, and it can simply do nothing.
• Winter’s Wrath applies Frost stacks with two mace swings, and at maximum stacks Permafrost becomes a point-and-click stun with no dodge window.
• Arctic Assault charges until it strikes a champion and knocks them airborne, ending any repositioning attempt outright.
• By level 18 Sejuani carries 126.7 armor against Quinn’s purely physical damage, along with 2568 health to her 2384.

What counterplay exists runs through vision and spacing rather than trading. Quinn attacks from 525 units to Sejuani’s 150 and moves at 330 against 340, and Heightened Senses revealing a large area is the difference between meeting Glacial Prison in the open and reading the approach early. Difficulty is rated 5 for Quinn and 4 for Sejuani, so the tank side is also the simpler side to pilot. Both use Mana and both open with 32 magic resist, which leaves armor and mobility as the only meaningful early divergence. Her full kit is on the Sejuani page.
