Renekton is a strong early-game laner, especially at level 6 with his ultimate, excelling in short trades and all-ins, making early jungle support crucial.
He struggles against certain champions like Rumble and Poppy; adapt your playstyle by building Stridebreaker (teamfights), Shojin (duels), or Eclipse (solo kills).
Be wary of large enemy minion waves when fighting him, and capitalize on impulsive Renekton players who might overcommit with their ultimate or teleport.
