Zac Jungle build guide: runes, items and skill order
This Zac Jungle build covers League of Legends patch 16.20. Compare the selected runes, starting items and core purchases before the match, then adapt your later purchases to enemy damage and defenses. The source recommendations use the Gold filter across all servers.
For Zac runes, this setup uses Aftershock with Precision as the secondary path. Check the highlighted stat shards as well: they are part of the rune page, not extra items. Hover or tap a rune to read its effect before deciding whether it suits your matchup.
The displayed Zac skill order starts with W and prioritizes E → W → Q. The level-by-level grid covers the first 15 levels supplied by the source. Follow that sequence as a reference while accounting for what your lane or team needs. Item win rates describe completed purchases and should be read alongside their game counts.
Which items should you build on Zac Jungle?
The most popular core items in this Zac Jungle build are Sunfire Aegis → Spirit Visage → Thornmail. Check starting items and boots separately, then compare later item options against the enemy team. This is a reference for patch 16.20, not a fixed purchase order for every match.
Which runes should you choose for Zac Jungle?
For the selected Gold rank filter, the rune page uses Aftershock with Precision. Review each rune tooltip and the selected stat shards before entering champion select.
How do you compare Zac builds by rank?
Use the rank selector to view a separate build and win rate for Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, Master, Grandmaster or Challenger. Keep the same role when comparing. A small sample is less reliable, and a higher win rate alone does not prove a better build.
How this build works
Core purchases
The most popular core combination in the source is Sunfire Aegis → Spirit Visage → Thornmail. Treat it as a starting point: choose defensive or penetration options for the opponents you are facing.
Read the sample
The core combination has an observed win rate of 55.47% across 1,691 games. These are games that reached this purchase combination, not all games played by the champion. A completed build can appear stronger because winning players can afford more items.

Read the guideAbout Zac
Zac is the product of a toxic spill that ran through a chemtech seam and pooled in an isolated cavern deep in Zaun's Sump. Despite such humble origins, Zac has grown from primordial ooze into a thinking being who dwells in the city's pipes, occasionally emerging to help those who cannot help themselves or to rebuild the broken infrastructure of Zaun.
