Early: earn the angle before you spend the engage
0:00–about 14:00, especially level-2 races, wave crashes, and first objective setup windows
Build a lane state that gives you an approach angle rather than forcing every cooldown. During the first waves, respect the level-2 race: if your duo reaches level 2 first and the enemy is exposed, threaten Q/W with ADC follow-up; if you are behind the race, give up dangerous last hits until both kits are online. Build Trample stacks by damaging enemy champions when they must walk up, and value Triumphant Roar charges from controlled trades and nearby deaths. Transition when a crash creates a recall or visible roam; if behind, preserve experience and wait for the enemy to overextend instead of diving through a large wave.
