Vex vs Jayce Counter Pick
Matchup Summary
What the Data Means
Only 123 games stand behind the 58.5% Vex win rate against Jayce on patch 16.13.1, so treat it as a hint about the matchup rather than a settled answer.
The logic behind it makes sense. Jayce switches between stances: Mercury Cannon / Mercury Hammer trades his form for different abilities and extra range, and Hextech Capacitor gives him movement speed each time he swaps. The base attack range of 125 is the hammer’s number, and the champion’s challenge comes down to picking the right form at a difficulty rating of 7. Acceleration Gate adds more movement speed to his side. Vex, meanwhile, punishes hesitation: Personal Space grants shields and damage, Looming Darkness slows enemies through Gloom, and Doom ‘n Gloom inflicts fear.
Damage type makes the fight easier to follow. Jayce’s damage is physical, so armor is the right defensive stat to build, and his base armor of 22 is the weakest defensive number on either champion’s stats. Their health is almost the same at 590 each, although he reaches 2,443 by level 18 while she reaches 2,358, and both have a movement speed of 335. Thundering Blow pushing her back is his cleanest counter to Shadow Surge, which marks a target and then dashes in to finish it. Both champions use mana, and his base attack damage of 59 compared with her 54 makes an early trade in cannon form a real threat.
