Prioritize safe farming and stacking (Q) to outscale Aatrox's early pressure.
Avoid giving Aatrox free lane control; keep the wave near your side to minimize his (Q) sweet spot threat.
This is a scaling juggernaut vs lane bully matchup where Nasus must survive early and become a side-lane threat.
Trading pattern
Trade only when (W) is available to slow Aatrox and prevent his disengage.
Avoid fighting right after Aatrox uses (Q) or (E), as his threat drops until cooldowns reset.
Use (R) and high (Q) stacks to force extended trades when Aatrox cannot safely disengage.
Danger windows
Be cautious of (Q) sweet spots chained with (E) repositioning, especially before you have (R) and stacks.
Respect his (W) pull zone which can trap you and lead to extended trades.
Avoid extended fights before your (R) is up or stacks are meaningful, as Aatrox's healing and damage dominate early skirmishes.
Early game
Focus on last-hitting with (Q) and avoid extended trades before level 6.
Use (W) to punish Aatrox when he overcommits or walks into your slow range.
Keep the wave controlled near your tower to reduce Aatrox's ability to land (Q) sweet spots and chain trades.
Power spikes
At level 6, use (R) to survive longer trades and punish Aatrox if he stays in range.
Once (Q) stacks are high, pressure side lanes and force Aatrox to respond to your dueling threat.
Respect Aatrox's level 6 (R) spike which increases his sustain and reset potential; disengage if he activates it without a clear advantage.
Win conditions
Survive early lane pressure by stacking (Q) safely and controlling the wave near your side.
Use (W) slows and (R) durability to punish Aatrox when he overextends or mispositions.
Transition to side-lane pressure once stacks and (R) are available, forcing Aatrox to respond and enabling your team to capitalize on your splitpush threat.
