Jhin vs Kog’Maw Counter Pick

Bio-Arcane Barrage is the reason the range column misleads. Kog’Maw starts at 500 attack range, fifty short of Jhin’s 550, but his W adds range to every basic attack and converts them into percentage-of-maximum-health magic damage. Once it is active the shorter-ranged carry becomes the longer-ranged one, and Jhin’s 655 starting health with 2,474 at level 18 turns from an asset into a bigger target.

The result across 1,366 games on patch 16.13.1 is 45.5% for Jhin, which the difficulty scale calls Hard. His pattern of fixed four-shot bursts works best against opponents who must walk into his range; Kog’Maw does the opposite, and Living Artillery keeps applying pressure from outside any reasonable trade distance while gaining damage against low-health targets. Caustic Spittle corrodes armor and magic resistance as well, undercutting whichever defensive item Jhin buys first, and it grants Kog’Maw attack speed at the same time. Void Ooze compounds the problem by leaving a slowing trail rather than a single hit, which is what converts a walk-up into a kill against a champion who cannot dash across it. His outs are positional. Captive Audience covers the retreat paths that trail forces, and Curtain Call punishes an opponent whose 330 movement speed and complete absence of a dash match Jhin’s own, so neither escapes the other’s ultimate. Icathian Surprise also means finishing him at melee distance still costs true damage. The Kog’Maw page lists the on-hit scaling.
