Team Synergy

Zac is a disruption engine. In Mayhem, where damage flies constantly, he forces enemies to respect his engage range or die trying. He needs teammates who can capitalize on his knock-ups and follow up when he dives deep. He does not need a babysitter; he needs a firing squad. The champion functions best as a primary engage or a counter-engage anchor, depending on how the enemy team moves.

Core Team Needs

  • Follow-up Crowd Control: Zac’s slams scatter people. He needs allies with area stuns or roots to lock down targets after his initial knock-up ends.
  • Reliable Burst Damage: Zac creates openings, but he often cannot finish high-health targets alone before they recover. He needs mages or assassins who can delete a target during the two-second window he provides.
  • Long-Range Poke Pressure: While Zac wants to go in, having a poke mage forces enemies to hide behind minions. This makes landing the Elastic Slingshot easier, as enemies are too busy dodging skillshots to check the fog for his charge-up.

Top Synergy Pairings

1. Orianna (High Value)
This is the classic "Ball Delivery Service" combo, and it remains terrifying in Mayhem. Zac engages from fog of war with a charged Elastic Slingshot. Orianna places her ball on him before he launches. When Zac lands, he knocks everyone up; Orianna instantly activates Shockwave. The chain crowd control leaves the enemy team airborne for nearly three seconds.

  • Best Scenario: Zac lands a multi-man Slingshot onto a clumped backline. Orianna follows with Command: Shockwave to keep them locked in Zac’s ultimate bounce radius.
  • Enemy Answer: Quick reaction crowd control like Soraka silence or Janna tornado can stop Zac mid-air, dislodging the ball and ruining the combo timing.
  • Failure Risk: If Orianna is too slow, enemies may flash out before the Shockwave lands, leaving Zac isolated.
  • Recovery: Zac uses his ultimate to push enemies back toward his tower or uses Cell Division passive to bait cooldowns while Orianna repositions.

2. Miss Fortune (High Value)
Zac is the perfect setup for "Bullet Time." His Elastic Slingshot and Let’s Bounce both group enemies tightly in a small circle. Miss Fortune loves targets that cannot move. When Zac lands, Miss Fortune channels her ultimate, stacking massive damage on top of the crowd control. In Mayhem’s chaotic fights, this combination often wipes a team from full health.

  • Best Scenario: Zac engages over terrain, knocking up three or more enemies. Miss Fortune channels her ultimate immediately, covering the entire knock-up zone.
  • Enemy Answer: Hard engage on Miss Fortune. If the enemy assassin or diver ignores Zac and goes straight for the gunner, the combo falls apart.
  • Failure Risk: Miss Fortune gets interrupted or forced to move. Zac is then left in the middle of the enemy team with his damage output mostly spent.
  • Recovery: Zac peels for Miss Fortune using his remaining slams, buying her time to reset and cast again or escape.

3. Yasuo (Strong Value)
Yasuo’s Last Breath requires airborne targets. Zac is an airborne generator. Every part of Zac’s kit—his passive blob pickup burst, his stretch, his slingshot, and his ultimate—counts as a knock-up for Yasuo. This synergy is almost effortless. Zac lands, Yasuo clicks R, and the chain CC continues.

  • Best Scenario: Zac hits a long-range Slingshot onto a priority target. Yasuo dashes through minions to reach the fight and instantly ults the knocked-up victims.
  • Enemy Answer: Point-and-click crowd control. If Yasuo gets stunned or grounded before he can ult, the chain breaks.
  • Failure Risk: Yasuo might ult too early, leaving enemies still alive and ready to fight back while Zac’s cooldowns are down.
  • Recovery: Zac uses his ultimate to push enemies away from Yasuo, creating space for the swordsman to stack his flow and dash to safety.

4. Vel’Koz (Strong Value)
Vel’Koz needs enemies to sit still for his true damage beams. Zac provides that stillness. When Zac engages, enemies often panic and burn their movement abilities. Vel’Koz can then land his knock-up or slow, setting up his ultimate. The sheer damage output of a full-channel Lifeform Disintegration Ray on a team stuck in Zac’s crowd control is overwhelming.

  • Best Scenario: Zac dives the backline. The enemy support tries to peel. Vel’Koz uses the chaos to land a full-duration ultimate on the enemy frontline and backline simultaneously.
  • Enemy Answer: Long-range poke or disengage. If Vel’Koz gets poked down before the fight starts, he cannot follow up on Zac’s engage.
  • Failure Risk: Vel’Koz misses his crowd control or gets flanked. Zac is left swinging alone while the enemy collapses on the squishy mage.
  • Recovery: Zac switches to a defensive peeling role, using his body to block skillshots aimed at Vel’Koz, allowing the researcher to reset.

5. Lulu (Situational Value)
Lulu turns Zac into an unkillable monster. In Mayhem, Zac already heals constantly. Lulu’s Wild Growth adds massive health, a slow, and a knock-up on top of Zac’s kit. When Zac goes in, Lulu ults him. The resulting AoE knock-up combined with Zac’s own disruption creates a massive zone of denial. Whimsy also saves Zac from burst, letting him survive long enough to collect blobs.

  • Best Scenario: Zac initiates. Lulu ults him the moment he lands. The double knock-up disrupts the enemy formation, and Zac becomes too large to ignore.
  • Enemy Answer: Anti-heal and percent health damage. If the enemy builds Executioner’s Calling or Liandry’s, the extra health from Lulu matters less.
  • Failure Risk: Lulu uses her abilities on the wrong target. If she shields herself instead of Zac, Zac gets burst down before his passive triggers.
  • Recovery: Lulu uses Polymorph on the biggest threat to Zac, buying time for his blobs to revive him or for cooldowns to reset.
