Kha'Zix deals massive damage to isolated targets; always prioritize engaging enemies that are alone. An isolated full combo is lethal to squishies and even some bruisers.
Early game snowballing is crucial. Secure kills through counter-jungling or ganks to quickly gain a lead and dominate the game.
Always evolve Q first for burst damage. Subsequent evolutions should be flexible based on team and enemy composition, focusing on assassinating vulnerable targets.
