Jhin & Shaco Synergy

Why this duo works

Shaco's boxes and poison reliably mark enemies to set up guaranteed Deadly Flourish (W) roots, locking targets into lethal CC chains. Their combined traps create an impenetrable defensive zone that protects the immobile Jhin from ganks and dives while their missing-health executes seamlessly finish off low-health targets.

Playing the duo

Layer Captive Audience (E) traps adjacent to Jack in the Boxes (W) in side bushes to create defensive deathzones that deter enemy engage supports from sweeping or facechecking.

Jack in the Box (W) fear and Two-Shiv Poison (E) apply damage and debuffs that mark enemies for Jhin's Deadly Flourish (W), enabling Jhin to land an instant long-range root while the enemy is feared or slowed.

Stacking Shaco's Jack in the Box (W) with Jhin's Captive Audience (E) forces enemies triggered by the fear to flee slowly through blooming lotus traps, ensuring the delayed trap detonation hits before they can escape.

Both champions feature heavy missing-health execute damage (Shaco's Two-Shiv Poison deals 50% bonus damage to targets below 30% health, while Jhin's 4th Whisper shot executes based on missing health), allowing them to reliably secure kills once a target drops below half health.

How to play as Jhin

Hold Deadly Flourish (W) until an enemy triggers Shaco's Jack in the Box (W) or gets hit by Two-Shiv Poison (E); chaining your root immediately extends the crowd control long enough for multiple box hits and Dancing Grenade bounces.

How to play as Shaco

Place Jack in the Boxes (W) along river choke points and behind Jhin's farm line rather than only in lane bushes, establishing a retreat safety net so Jhin can push and harass without fear of jungle ganks.

When Jhin activates Curtain Call (R), use Deceive (Q) to flank behind retreating targets and slow them with Two-Shiv Poison (E), steering them back into Jhin's firing cone.
