Use Trundle's superior early dueling and invade resistance to contest Nasus's jungle camps and river control before he scales.
Focus on denying Nasus free farm and stacks by aggressive counter-jungling and controlling Scuttle vision and objectives.
Prioritize extended fights around your (W) and (R) to exploit Nasus's low early pressure and punish his weak early dueling.
Jungle Plan
Path aggressively to invade Nasus early and deny his camp stacks before he reaches key scaling thresholds.
Contest first Scuttle when your lanes can follow or counter-gank to secure river control and objective vision.
Use (E) to trap Nasus near objectives or narrow jungle exits, then force extended duels inside (W) and apply (R) to drain his resistances.
Danger windows
Beware of Nasus's level 6 (R) active during extended fights, as he gains durability and punishes prolonged trades.
Avoid isolated river fights or forced smite contests when Nasus has lane priority or (R) active, as he can survive and counterattack.
Be cautious when low on health during clears or objective setups, as Nasus can capitalize on your vulnerability with his sustain and slows.
Early game
Start with a path that leads to early river Scuttle to leverage Trundle's strong early pressure and contest Nasus's first clear.
Invade Nasus's jungle camps when nearby lanes have priority to force him off stacks and delay his scaling.
Avoid fighting Nasus if he has lane priority or (R) active; instead, focus on safe clears and counter-ganks until you can force fights.
Power spikes
Level 6 (R) is a major spike; use it on Nasus to reduce his tankiness and win extended fights before he stacks.
First dueling item spike strengthens your side-lane pressure; force isolated fights where you can pressure towers and deny Nasus's scaling.
Nasus's level 6 (R) and high (Q) stacks increase his threat; respect his extended fight potential and avoid prolonged isolated skirmishes after this point.
Win conditions
Convert early invade and Scuttle control into dragon and Rift Herald priority to snowball your lead and deny Nasus safe scaling.
Use (E) and (R) to trap and drain Nasus in side-lane duels, forcing him off farm and preventing high (Q) stack accumulation.
Leverage your superior dueling and objective control to pressure side lanes, force Nasus into unfavorable fights, and secure mid-game map control.
