Jayce vs Gragas Counter Pick
Matchup Summary
What the Data Means
Movement speed frames the whole exchange. Gragas travels at 330 while Jayce sits at 335 and gains more on every weapon swap through Hextech Capacitor, with Acceleration Gate available to extend it further. Across 107 games on patch 16.13.1 Jayce holds 59.8 percent, on a sample small enough to warrant caution.
Gragas is far tougher once he arrives: 640 health at level one rising to 2,595, 38 armor rising to 123, and mixed damage that forces a split defensive purchase. Body Slam is the ability that closes distance and stuns, and Explosive Cask can knock a target back into the fight instead of out of it. Happy Hour heals him periodically whenever he casts, which makes chip damage unreliable as a plan. Shock Blast fired through the gate is the counter-argument. It gains speed and range, arrives from beyond the reach of the stun, and costs Jayce nothing in position. Hammer stance then supplies Thundering Blow to reverse a Body Slam that has already connected. Gragas is rated 5 for difficulty against 7, so the favourable number belongs to the harder kit, and it disappears when the stances are swapped carelessly. Barrel Roll grows more potent the longer the cask sits before detonating, which rewards patience from a champion holding 64 attack damage against 59.
