Zac

Tank / Fighter

League of Legends (PC)

Zac was last adjusted in Patch 26.5 (). Across 56 patches, Zac has received 13 buffs, 12 nerfs, 30 adjustments since release in Patch 3.5.

Abilities
Cell DivisionPC
Passive - Cell Division
Range: 700

Innate - The Secret Weapon: Zac gains increased percentage size equal to 1.5% of his bonus health, capped at 35% increased size at 2333.33 bonus health. Zac's size also reduces based on his missing health, down to 70% total size while at 0% health.

Innate - Goo: Whenever Zac damages at least one enemy with an ability, he sheds a number of chunks of himself to a nearby location, landing towards nearby sight enemy champions and lasting for 6 seconds. * Stretching Strikes: 1 chunk for the initial hit, and 1 chunk if the second hit is on a different unit * Unstable Matter: 1 chunk if it hits at least one unit * Elastic Slingshot: 1 chunk for each enemy champion hit, with a minimum of 1 if it hits at least one unit * Let's Bounce! : 1 chunk for each bounce that hits at least one unit

Both Zac and enemy champions can interact with a chunk by being within 50 units of it: an enemy will destroy it, while Zac will consume it to heal for 4% - 8.47% (based on level) of his maximum health.

Innate - Cell Division: Periodically, upon taking death, Zac enters resurrection for 8 / 7 / 6 / 5 / 4 seconds, instantly restoring 50% of his maximum health and becoming untargetable and lockout for the duration. Zac then splits into four uncontrollable bloblets away from his location, though stopping at terrain. After 1.5 seconds of the bloblets being untargetable, they start moving toward Zac's location over the remaining duration. Any damage the bloblets receive, excluding damage dealt in excess of each bloblet's total maximum health, is also redirected to Zac as true damage. While in resurrection, Zac cannot take damage from sources other than the redirected damage from his bloblets.

After the duration, Zac is revived with 10 - 50% maximum health. Zac will die once all bloblets are killed.

Stretching StrikesPC
Q - Stretching Strikes
Cost: 8% Current Health
CD: 14 / 12.5 / 11 / 9.5 / 8
Cast Time: 0.33
Range: 800 / 80
Effect Radius: 900

Active: Zac stretches his left arm in the target direction that catches the first enemy hit, dealing magic damage, slow them by 40% for 0.5 seconds, and forming a tether between Zac and the target for 2 seconds, during which they are true sight.

Magic Damage: 60 / 90 / 120 / 150 / 180 (+ 30% AP) (+ 3% of Zac's bonus health)
Total Magic Damage: 120 / 180 / 240 / 300 / 360 (+ 60% AP) (+ 6% of Zac's bonus health)

While the tether persists, Zac's next basic attack is replaced by a second Stretching Strike, empowering it to have a 0.25 -second cast time and gain 25 bonus attack range. This attack triggers on-attack effects, but cannot critically strike nor apply on-hit effects.

If the two Stretching Strikes affect different targets, both are knockdown and root for 0.5 seconds while the secondary target is dealt the initial magic damage and applied the same slow. After a 0.4 -second delay, Zac displaces them toward each other over 300 units, though not through terrain.

If the two targets are within 700 units of each other, they are instead slammed together through the displacement. Upon impact of each other, both targets are airborne and stun for 0.25 seconds and all enemies within the impact are dealt the initial magic damage and applied the same slow.

Both Stretching Strikes (the cast and the empowered attack) basic attack reset Zac's basic attack timer. Zac is unable to move or attack while his left arm is in flight.

Unstable MatterPC
W - Unstable Matter
Cost: 4% current Health
CD: 5
Cast Time: None
Range: 350

Active: Zac explodes to deal magic damage to nearby enemies, the damage based on the target's max health ratio is capped at 200 against minions and monsters.

Magic Damage: 40 / 50 / 60 / 70 / 80 (+ 4 / 5 / 6 / 7 / 8% (+ 3% per 100 AP) of target's maximum health)
Capped Non-Champion Damage: 240 / 250 / 260 / 270 / 280

Zac grants ghost to aggroed monsters hit for 5 seconds.

Unstable Matter's current cooldown is reduced by 1 second whenever Zac collects a Cell Division chunk.

Elastic SlingshotPC
E - Elastic Slingshot
Cost: 4% Current Health
CD: 22 / 19 / 16 / 13 / 10
Cast Time: None
Range: 1200 / 1350 / 1500 / 1650 / 1800
Effect Radius: 265

Active: Zac channel for up to 4.5 seconds to increase Elastic Slingshot's range over a cone in the target direction.

Maximum Range Channel Duration: 0.9 / 1 / 1.1 / 1.2 / 1.3 seconds
Magic Damage: 60 / 105 / 150 / 195 / 240 (+ 80% AP)

Elastic Slingshot can be recast within the duration. If Zac cancels the channel himself, or the charge completes without reactivation, 50% of Elastic Slingshot's health cost and cooldown are refunded.

Recast: Zac dash to the target location within the boundaries of the cone. Upon landing, he deals magic damage to nearby enemies and airborne and stun them for 0.5 seconds, increased to 1 second if Elastic Slingshot was charged for more than 1 second.

Let's Bounce!PC
R - Let's Bounce!
CD: 120 / 105 / 90
Cast Time: 0.3
Effect Radius: 300

Active: Zac bounces after the cast time, then bounces 3 additional times each second over 3 seconds. Each bounce deals magic damage to enemies hit, airborne over 1 second, and slows them by 20% for the same duration. An enemy can be hit by multiple bounces, but ones beyond the first deal 50% damage to them and do not apply the airborne.

Primary Magic Damage: 120 / 190 / 260 (+ 40% AP)
Reduced Magic Damage: 60 / 95 / 130 (+ 20% AP)
Total Magic Damage: 300 / 475 / 650 (+ 100% AP)

Zac can move while Let's Bounce! is active, gaining ghosting and 20% - 50% (based on level) bonus movement speed, but becomes unable to declare basic attacks, Stretching Strikes, and Elastic Slingshot. He also automatically consumes all Cell Division within the bounce radius.

Patch 26.5change

Elastic Slingshot

  • Bug Fix: Fixed a bug where it could be heard in Fog of War by nearby enemies.
Patch 26.4nerf

Zac has been truly explosive in the new season, and while his ability to tank and engage are meant to be core strengths, he's also too lethal for a tank with deep backline target access. So to give everyone a fair shot against him, we're reducing his burst damage when it's slime time, especially against squishies.

Patch 3.5new

Zac added to League of Legends

Cell Division (Innate)

  • When any of Zac's abilities hit an enemy, a piece of him falls to the ground. Zac can pick up fallen pieces to recover health. When Zac dies he splits into four blobs. These fragments will attempt to reform over a short duration. If any survive, Zac revives with a percentage of his maximum health based on the number of remaining blobs.

Stretching Strike (Q)

  • Zac throws a two-handed punch that deals damage and slows targets in a line.

Unstable Matter (W)

  • Zac's body explodes outward, dealing flat damage to surrounding enemies. Enemies struck also take damage based on their maximum health.

Elastic Slingshot (E)

  • Zac is immobilized as he charges up a dash toward the target location. The range of Elastic Slingshot increases up to a cap as Zac charges the ability. Zac then fires himself towards the target location, damaging and stunning all nearby enemies upon landing.

Let's Bounce! (Ultimate)

  • Zac bounces into the air, immediately knocking up, slowing and damaging nearby enemies. Once airborne, he bounces three times, dealing damage with each impact.
