Quinn vs Rammus Counter Pick

Rammus turns Quinn’s damage back on her, and the record is blunt: 37.2% from 156 games on patch 16.13.1. Quinn is a purely physical champion, and Defensive Ball Curl vastly increases armor and magic resist while returning damage to anything attacking him. A marksman whose output is basic attacks and Harrier procs is the ideal victim for that, and Spiked Shell converts his armor and magic resist into bonus attack damage, so stacking resistances makes him more threatening rather than merely sturdier.

Mobility does not rescue her. Powerball accelerates into a slow on impact, Soaring Slam lands as magic damage with a slow and adds a knock-up when it follows Powerball, and Frenzying Taunt forces Quinn to walk in and attack him. Once taunted, 525 attack range is worth nothing and Vault is usually already spent. Armor penetration is the only itemisation that keeps her damage relevant, and even then Rammus finishes with 111.5 armor to her 107.9, 2345 health to her 2384, and moves at 335 against her 330. Both carry a difficulty rating of 5, so the deficit is structural rather than mechanical, and the practical answer is to avoid isolated jungle contests entirely. Both champions run on Mana and both open with 32 magic resist, so nothing in the resource or resistance profile separates them at level one. His kit is on the Rammus page.
