Sion vs Locke Counter Pick
Matchup Summary
What the Data Means
A 57.9% win rate for Sion over 649 recorded top games on patch 16.13.1 makes this one of the friendlier assignments the Undead Juggernaut gets. Locke is listed as an Assassin and Mage but deals physical damage, which runs straight into Sion’s best defensive stat: 36 armor at level 1 climbing to 107.4 by level 18. Silver Stake adds magic damage on hit that scales with missing health, so the danger is not the first exchange but the fourth, once Sion is already low.
The 50-unit reach edge, 175 against 125, is small but real, and it decides who gets the first tick of a trade. Sion also moves at 345 against 340 and can charge Decimating Smash from outside Locke’s auto range. Soul Ignition is the window worth punishing: Locke pays health for attack speed and movement speed, then heals part of it back at the end, so a Roar of the Slayer slow during that burn cuts the payoff badly. Ashen Pursuit teleports before dashing, which means Locke can reposition through a charged swing, and Purgatory executes low targets, though Glory in Death partially answers that since the reanimation phase still deals damage. Sion opens with 655 health and 68 attack damage against Locke’s 655 and 58, ending at 2,134 to 2,508. Both run on mana and both are rated 5 for execution difficulty, so the gap is positional rather than mechanical. Kits: Sion, Locke.
