Create a controlled first engage
0:00 until the lane stops being the primary pressure point; strongest when your duo has level, wave, and ally-follow-up advantage
In the opening waves, identify whether your ADC wins the level-2 race. If your duo reaches level 2 first or has a larger wave, pressure with the threat of E and wait for the enemy to last-hit before committing Q; Sunlight matters only when an ally can consume it. If you lose the race, give up dangerous CS rather than entering a full enemy wave. Crash before recalling, and use a crashed wave as the condition for a safe river move.
