Kayn vs Nunu & Willump Counter Pick
Matchup Summary
What the Data Means
The health column reads like a mismatch. Nunu & Willump finish on 2,140 health with 100.4 armour at level 18 and start on 610 health with 29 armor, behind Kayn on every one of those figures. Across 761 games on patch 16.13.1 Kayn still holds only 46.8%.
Objectives explain most of the gap. Consume bites a minion, monster or champion for damage and healing, which keeps the pair topped up and threatens every neutral objective directly. Snowball Barrage roots champions and large monsters caught by its throws, Biggest Snowball Ever! grows in size and speed as it rolls before knocking up, and Absolute Zero slows an area for the duration before detonating for heavy damage. That is three separate ways to stop a melee attacker from completing his approach.
Kayn’s damage is physical and theirs is magic, and both carry 32 base magic resist, so neither buys a clean counter early. His edge is not raw pace, since they move at 345 to his 340, but terrain: Shadow Step crosses walls the yeti must walk around, and Reaping Slash adds a dash on top. Blade’s Reach slows at range, which is the tool that matters once a snowball is already rolling. Kayn is rated 8 for difficulty against their 4.
