Prioritize safe farming and stacking (Q) to reach your late-game juggernaut power against Trundle's moderate lane pressure.
Avoid giving Trundle extended fights early; focus on a controlled wave near your side to minimize his (W) zone impact.
This is a scale vs mid-tier pressure matchup where Nasus must survive early and become a side-lane threat.
Trading pattern
Trade only when (W) is available to slow Trundle if he overcommits; otherwise, avoid early trades.
Use (R) to extend fights once stacked, but disengage if Trundle uses (E) to block your escape.
Punish Trundle's cooldowns on (W) and (E) by stepping forward for quick (Q) stacks or short trades.
Danger windows
Beware of (W) zone where he gains healing and attack speed; avoid fighting inside it early.
Respect the threat of (E) pillar cutting off your escape; maintain spacing to prevent being trapped.
Early levels before (R) and meaningful (Q) stacks are your most vulnerable; avoid all-ins and tower dives during this phase.
Early game
Focus on last-hitting with (Q) stacks while using passive sustain to stay healthy under pressure.
Use (W) to punish Trundle's overextensions but avoid early fights before your stacks and (R) are active.
Keep the wave near your tower to reduce Trundle's ability to force extended trades with (W) and (E).
Power spikes
At level 6, activate (R) to survive Trundle's extended trades and punish him if he cannot kite you.
Once (Q) is highly stacked, pressure side lanes to force Trundle to respect your damage and (W) slow.
Respect Trundle's level 6 (R) stat drain; avoid extended fights when it is available to prevent losing durability.
Win conditions
Survive early pressure by safe stacking and wave control, then leverage high (Q) stacks and (R) to win extended side-lane duels.
Use (W) to punish Trundle's overextensions and force him to respect your damage output.
After reaching key item and stack thresholds, pressure side lanes to create map pressure and force Trundle to respond, enabling your team to capitalize elsewhere.
