Sejuani vs Jarvan IV Counter Pick
Matchup Summary
What the Data Means
Dragon Strike lowers the armour of everything in its path, and armour is the stat Sejuani is built out of: 34 at level one rising to 126.7, the number that justifies walking in first. Jarvan IV shreds it, then leans on physical damage and Martial Cadence, whose opening hit on a target scales with that target’s current health. Over 648 games on patch 16.13.1 Sejuani comes out at 45.7%.
The engage patterns are near-identical in intent and unequal in reliability. Arctic Assault charges forward, knocks enemies into the air and stops on the first champion struck; Demacian Standard combined with Dragon Strike pulls Jarvan IV to his own flag with the same knock-up attached, and Cataclysm then terraforms an arena around the target so leaving is not an option. Golden Aegis shields him while slowing everything nearby, which interferes directly with Winter’s Wrath applying Frost and Permafrost needing maximum stacks to stun. Frost Armor’s slow immunity is the counter to that specific problem, but it only exists after time spent out of combat. Health growth favours Sejuani at 630 to 2,568 against 640 to 2,408, both move at 340, and the 25 units between 150 and 175 attack range belong to Jarvan. Both spend mana, and Demacian Standard passively grants him bonus attack speed on top of everything its flag enables.
