Tryndamere wants to pressure Aurelion Sol early to deny his scaling and avoid passive farming lanes.
Focus on building Fury and creating side-lane pressure to force Aurelion Sol into uncomfortable fights or missed farm.
This is a snowball vs scale matchup where Tryndamere must leverage early and mid-game all-ins to prevent Aurelion Sol from reaching his late-game teamfight power.
Trading pattern
Stack Fury through wave control and threaten short trades with autos before committing with (E) for chase.
Use (W) slow to reduce Aurelion Sol's damage output and prevent his easy disengage.
Avoid using (E) forward if Aurelion Sol can kite or disengage cleanly; instead, punish after he wastes his mobility or poke cooldowns.
Danger windows
Be cautious when Fury is low, (E) is down, or (R) is unavailable, as Aurelion Sol can punish with poke or kiting.
Avoid extended fights before level 6 when Aurelion Sol can poke safely from range.
Ping and punish Aurelion Sol's roams by hard pushing waves and taking plates to maximize lead and reduce his map impact.
Early game
Use early waves to build Fury and threaten quick trades before Aurelion Sol has his full kit.
Avoid all-ins without Fury or (R) available to prevent being poked down by Aurelion Sol's ranged abilities.
Punish Aurelion Sol's limited early agency by forcing trades when his (Q) and (W) are on cooldown or missed.
Power spikes
At level 6, use (R) to commit to all-ins that Aurelion Sol cannot safely escape or kite.
After two core items, increase side-lane pressure and force Aurelion Sol to respond or lose objectives.
Respect Aurelion Sol's spike after completing Rylai's and his ultimate upgrade at 75+ stacks by playing safer and avoiding extended fights.
Win conditions
Deny Aurelion Sol free scaling by forcing early fights with stacked Fury and (R) windows.
Use side-lane pressure and splitpush to force Aurelion Sol into unfavorable one-on-one duels.
Convert low-health fights with (R) into kills or tower damage to snowball the lead and close the game before Aurelion Sol scales.
