Olaf must pressure early to deny Nasus safe stacks and prevent his late-game scaling threat.
Use high early agency and lane pressure to force Nasus into defensive farming rather than passive scaling.
This is a snowball vs scale matchup where Olaf needs to capitalize on early power to keep Nasus weak.
Trading pattern
Start trades by landing (Q) and picking it up to maintain chase and pressure Nasus's low mobility.
Use (R) only when you can commit fully without Nasus being able to kite or disengage.
Punish Nasus after he wastes (W) or misses (Q) stacks by forcing extended fights where your true damage and crowd control immunity dominate.
Danger windows
Be cautious when your (Q) is on cooldown or missed, as Nasus can retaliate with (W) slow and stack damage.
Avoid fighting Nasus during his (R) duration if you cannot stick to him, as he becomes tankier and punishes extended trades.
Watch out for ganks when pushing aggressively; Nasus can turn fights with his durability if you get caught out.
Early game
Aggressively use (Q) to poke and slow Nasus, forcing him to miss last hits and delaying his stacks.
Avoid extended trades if you miss (Q) since Nasus can punish your cooldowns with (W) slow.
Use (W) shield and lifesteal from (E) to sustain through Nasus's poke and maintain lane control pre-6.
Power spikes
At level 6, use (R) to ignore (W) slow and extended fight durability, forcing all-ins when Nasus can't kite effectively.
After your first fighter item, pressure Nasus heavily in side lanes to deny his stacking and force fights.
Respect Nasus's level 6 (R) and high (Q) stack thresholds by avoiding prolonged fights without your (R) active and cooldowns ready.
Win conditions
Deny Nasus early farm and (Q) stacks by aggressive early pressure with (Q) axe slows and extended trades.
Use (R) to ignore his slows and crowd control, forcing straight-line fights where your true damage and sustain excel.
Snowball side-lane pressure post-level 6 and first item to prevent Nasus from reaching his scaling thresholds and win through anti-CC all-ins and chase.
