Favour timeline — the windows in Renekton's game plan

Read from Renekton's seat: which stage windows this plan plays for against Zac.

StageFavouredWhy
Level 1Even / skillNeither of you has a dash at level 1 and Zac's Q requires two hits to connect — farm safely and track where his passive blobs land so you can deny them on the next trade.
Level 2RenektonYour E-in plus empowered W-stun lands before Zac can respond; step on the blobs he drops on the engage hit to remove his only sustain tool.
Level 3RenektonFull kit online: your three-ability combo bursts him faster than his blob passive can regenerate HP and he has no mobility ability to escape the stun lock.
Levels 4-5RenektonZac cannot match your short-trade burst at 4-5 and Elastic Slingshot is a 21s wind-up at rank 1 — punish every whiff with the full E-W-Q rotation.
Level 6Even / skillLet's Bounce! knocks up on every bounce, but note Dominus adds bonus Health and Unstable Matter takes a percentage of it — anti-heal first, then commit.
First itemRenektonSundered Sky or Stride Breaker completes your stick-and-burst pattern; you can proc the empowered W-stun and chase through his entire blob-regen window before he escapes.
Two+ itemsEven / skillZac becomes a teamfight-initiator at full build and his R disrupts grouped melees — play side lane and avoid fighting him with teammates in bounce range.

How to beat Zac as Renekton: the early game

At level 1 you both sit even — Zac has no kill pressure and you lack your dash, so farm safely and track where his blobs land on the ground. The moment you hit level 2, E onto him and immediately step on any blobs he drops from the engage; denying that passive healing is as important as the W-stun itself. At level 3 with full kit you are clearly winning this lane: his Q (Stretching Strikes) requires two casts to pull him to you and his W (Unstable Matter) has no range — run the E-in, empowered W (3-hit 1.5s stun), Q-heal rotation and get out before his blobs respawn.
