Favour timeline — who owns each window

StageFavouredWhy
Level 1OlafYour worst level in the game — only Null Sphere up, no escape, and his Undertow (Q) slow lets him stick and grind you down with Vicious Strikes (W) sustain.
Level 2OlafHe gets his full early trade pattern online while you still have no mobility; Reckless Swing (E) true damage ignores Void Stone, so concede CS and don't contest.
Level 3OlafStill behind at his power floor — Force Pulse only charges as spells fly so you can't punish, and the Undertow axe pickup gives him every all-in reset.
Levels 4-5Even / skillLevel 6 is the swing: Riftwalk lets you blink over Undertow (Q) and out of his dive, so the slows that beat you early stop landing.
Level 6KassadinRod of Ages turns your survival into real burst; blink-trades chunk him faster than his lifesteal heals, and you start winning short windows.
First itemKassadinStacked Riftwalks plus Seraph's let you out-blink and out-burst him as his lifesteal-bruiser kit plateaus — you own the mid-game 1v1.
Two+ itemsKassadinFrom two items on you kite his every commit and burst him before Vicious Strikes sustains him back; only Ragnarok's true-damage window forces respect.

Early game (levels 1–5)

Levels 1-3 belong to Olaf and you just accept it — your only defensive button is Null Sphere's 1.5s shield, and his Undertow (Q) slow lets him stick while Vicious Strikes (W) sustains him through any trade you try. Don't auto-trade; last-hit from max Q range and bank the CS, because Void Stone's magic reduction does nothing against his physical axes and his Reckless Swing (E) is true damage anyway. The one trap to dodge is the Undertow axe on the ground — standing where it lands lets him grab it to reset the slow, so deny that spot and never walk into a slowed all-in this early.
