Recommended build

What players actually run on Jax on the current patch: summoner spells, skill priority, starting, core and late items, runes and skill order.

Every entry comes with its pick rate (how often it is chosen) and, where available, its win rate. For runes, Most Played is the page the majority takes and Best WR the variant that wins most among those with enough games: when they differ, the second is usually the sharper choice, the first the safer one.

Win rate by elo

Jax's win rate in each rank tier, from Iron to Challenger, plus all tiers combined.

A champion that climbs with rank is usually one that rewards mechanics or game knowledge; one that peaks in low elo is often easy to pick up and punished by better players. Read the tier you play in, not the average. Tiers with no data for this patch are hidden.

Counters and matchups

A preview of the counters page: the five opponents Jax struggles against the most, and the five it beats most often, on the current patch.

Percentages are Jax's own win rate in each duel, with the gap to its overall win rate. The full lists, with every matchup that has enough games, are on the counters page linked below each table.

Patch history

Balance changes that touched Jax, patch by patch, most recent first, as published in the official patch notes.

The ten latest patches are shown, the older ones fold out. Use it to read the win rate movements above: a jump right after a patch is usually a buff or a nerf, not a change in how people play the champion.
