Jhin excels against squishy champions but requires flexible itemization against tanks.
Always utilize your 4th shot. Place E in bushes or entry paths proactively. Use Q for maximum damage via minion bounces and R to execute low-health enemies.
For core damage, consider Stormrazor and Infinity Edge. If facing many tanks, pick the Cut Down rune and prioritize armor penetration items like LDR/Mortal Reminder early.
