Kog’Maw vs Seraphine Counter Pick

Seraphine is tagged as a support first and still takes the matchup: Kog’Maw wins 45.8% of 306 games on patch 16.13.1. The mechanism is crowd control against a champion with no way to avoid it. Beat Drop impairs movement in a line, Encore charms everything it touches and refreshes its range with every champion hit, and Stage Presence makes every third basic spell cast twice.

• A charmed or slowed Kog’Maw loses the only thing keeping him alive, which is distance; 330 move speed and no dash leave nothing in reserve.
• Surround Sound shields and hastes her allies, and heals them when she is already shielded, blunting the poke Living Artillery is supposed to accumulate.
• She also out-reaches him by twenty-five units at 525 against 500 for as long as Bio-Arcane Barrage is unavailable.

On raw statistics the comparison is lopsided the other way: 635 health against 570 at level one, 61 attack damage against 50, and 2,318 against 2,185 by level 18, with her 26 armor growing to only 97.4. That is exactly the profile Caustic Spittle and a percentage-of-maximum-health on-hit effect are built to break. Her mixed damage profile also means no single resistance item answers her cleanly. What separates the numbers from the result is how many chances he gets to apply them.
