The jungle race — the windows in Kha'Zix's plan

Read from Kha'Zix's seat: the race windows this plan plays for against Jax.

StageReadWhy
Level 1 ClearEven SkirmishEven at the first buff, for a concrete reason — Leap Strike trades onto anyone who steps up to contest their camp, while isolation-bonus Taste Their Fear chunks anyone who face-checks alone. Wait out the two-second dodge window before you swing — never auto into the spin, and let the camp timers choose the fight for you.
Level 2 SkirmishKha'Zix FavouredVoid Spike's heal-poke wins the slow trade war at river entrances. Counter Strike dodges camp autos and stuns whoever commits into them, so this is an edge and not a blowout — take the level-2 skirmish only with the HP and cooldown lead.
Level 3 RouteKha'Zix FavouredIso Q damage at level 3 already deletes squishier junglers caught solo, but the Empower-Leap burst plus E stun favors them into any auto-attacker. You still win the straight exchange at the opening scuttle; keep it short, keep it decisive, and keep the scuttle line yours.
Levels 4-5 MacroEven — Farm & TrackNeither of you owns 4-5. Since he farms 4-5 and takes short duels only where Counter Strike can eat a camp’s autos as well as yours, decide this window on vision and objective timers rather than on a duel.
Level 6 BreakpointRespect Jax's RThe six-spike belongs to Jax, and Kha'Zix's does not bridge the gap: the R resists plus Counter Strike out-stat every extended exchange. Trade in the gaps between his E windows and never stack autos into the dodge. Your own ultimate is a tool here, not a trump card — spend it to escape or equalize, not to start fights.
First Item SpikeUmbral Glaive / Eclipse SpikeUmbral Glaive clears the wards that would spot your approach and Eclipse adds a two-hit burst plus a shield, so an Isolated Taste Their Fear (Q) into Leap (E) now deletes squishy targets outright. Camps fall fast enough to clear a full side and still arrive at a lane. Use the spike to hunt lone targets in river and side lanes rather than joining even teamfights. Jax's first item is a real threshold — the Empower-leap burst goes from a trade to a kill on squishier junglers.
2+ Items ScalingDanger — Jax OutscalesThe clock is your enemy. He wins any extended duel on the map and will hold a side lane against two people, so close the game on the first two objectives you actually win.
