Cell Division

After using one of Zac's abilities, he creates a blob that lasts 6 seconds. The blob can be picked up immediately. If Zac walks over a blob, he absorbs it to regain 4% of his maximum health. If an enemy walks over a blob, it gets destroyed. If there is an enemy champion within 1000 units of Zac, the blobs produced from his abilities will spawn in between the enemy champion and Zac, and can be picked up 0.25 seconds after it spawns. The only exception is Let's Bounce, which lets you pick up blobs immediately, regardless of the time it takes for the blobs to land.

Upon taking fatal damage, Zac splits into 4 Bloblets that attempt to recombine. Each Bloblet has 12% of Zac's maximum health, and 50% of his armor and magic resistance. If any of the Bloblets remain after 8 seconds, Zac will revive with 10-50% health depending on the health of the surviving chunks. Zac's Bloblets are considered as minions, not champions. Ally champions can Teleport to Zac's Bloblets, just like Teleporting to minions. This also means that they can be Smited, Consumed, or pulled by Syndra. Although a Bloblet may seem visually farther than the other Bloblets, the respawn time will still be the same.

Stretching Strike

Zac punches enemies in a line, which deals magic damage and slows enemies for 2 seconds.

70 Magic Damage 110 Magic Damage 150 Magic Damage 190 Magic Damage 230 Magic Damage

Unstable Matter

Zac explodes, dealing damage plus a percentage of the enemies maximum health (capped 200 against minions and monsters). Zac can walk through monsters hit my Unstable Matter. Picking up a blob from one of Zac's abilities will reduce the cooldown of Unstable Matter by 1 second. If Unstable Matter is off cooldown, picking up a blob will reduce the cooldown of the next Unstable Matter by a maximum of 1 second.

Unstable Matter is the only ability Zac has that can be casted while using Let's Bounce.

Elastic Slingshot

Zac faces the direction cursor and begins channeling, increasing Elastic Slingshot's range over time. Zac then launches himself at the target. Enemies hit by Elastic Slingshot will get knocked up for 1 second. Elastic Slingshot will spawn and additional blob for each champion hit. Elastic Slingshot can be cancelled by moving, or exceeding the maximum channel time. If Elastic Slingshot is cancelled, 50% of the health cost and half the cooldown time will be refunded. CC such as a silence or a stun will cancel Elastic Slingshot.

let's bounce Let's Bounce let's bounce

Zac jumps into the air, and knocks back enemies for 1 second and slows them by 20% for 1 second. Zac then bounces 3 times, gaining a 20%-50% speed boost. Zac can only knock back targets once, and subsequent bounces on the same target deal half damage. While bouncing, Zac can use Unstable Matter, but not Stretching Strike or Elastic Slingshot.

Zac Jungle: Skill Sequence

Upgrade Let's Bounce whenever possible, since it's your ult. Max Elastic Slingshot first as it increases your damage and the distance, improving your ganking abilities. Unstable Matter is maxed second, as it's easily spammable and shreds jungle monsters and enemy tanks with percentage health damage. Stretching Strike is maxed last.
