Veigar vs Sion Counter Pick
Matchup Summary
What the Data Means
Sion carries the higher movement speed and the higher base attack damage — 345 and 68 against 340 and 52 — and converts both into a 42.9% result for Veigar across 119 games on patch 16.13.1, a small sample for a matchup this swingy.
An attack range of 550 against 175 should settle the matter and does not, because Unstoppable Onslaught is a steerable charge that gains speed the longer it runs and crosses the length of a lane. Event Horizon can stop it, which reduces the fight to a single-cast guessing game repeated whenever the ultimate returns. Decimating Smash knocks up when charged fully, Roar of the Slayer slows and shreds armor from a distance, and Soul Furnace both shields him and grows his maximum health permanently on kills.
The defensive picture is unusual. Sion opens thicker at 655 health to 580 yet finishes lower at 2,134 against Veigar‘s 2,416, since his scaling lives in that passive health growth rather than the base curve. His 36 base armor and 107.4 at level 18 dwarf 18 and 106.4, and his mixed damage means magic resistance alone will not cover him, while his own purchases only have to answer pure magic output. Glory in Death then returns him with rapid healing attacks, so killing him before an objective does not remove him from the fight. Difficulty ratings are 5 and 7.
