Zac Zac's Unstable Matter.png AoE damage and Cell Division.png self-healing skills provide him with a lot of flexibility on the battlefield. His Cell Division.png high level of sustainability makes him an ideal choice whether you're tearing through the jungle or trading hits in top lane.

In the jungle

Zac's combination of Unstable Matter.png area damage and Cell Division.png healing makes him a natural jungler. If you're partial to early game aggression, starting with an early Crest of Cinders.png lizard buff and spending your second skill point in Elastic Slingshot.png Elastic Slingshot can open early gank opportunities. Since Zac's abilities have no mana cost, you might also consider donating an early Crest of Insight.png golem buff to your AP carry. Once the action starts ramping up, you can make use of Elastic Slingshot.png Elastic Slingshot's massive range to create sneaky gank opportunities by circumventing popular ward locations.


Zac's skillset also makes him excel in top lane. His Unstable Matter.png AoE presence allows you to quickly clear waves from your turrets in high-pressure situations or shove the lane when you're on the offensive. The healing mechanic on Cell Division.png Cell Division also helps win exchanges with your lane opponent, allowing you to bully enemies back to base and create opportunities for counter-jungling or ganks. While you're roaming, the mobility afforded by Elastic Slingshot.png Elastic Slingshot can help you get the drop on an unsuspecting enemy or escape from sticky situations by hopping over terrain.

Team Fights

As the game progresses, Zac's extreme Elastic Slingshot.png mobility and strong Let&#039;s Bounce!.png crowd control make him a tremendous asset in team fights. With some patience and setup, you can use a fully channeled Elastic Slingshot.png Elastic Slingshot to deploy Let&#039;s Bounce!.png Let's Bounce! from huge distances. Once you're in the thick of it, the additional bounces from your Let&#039;s Bounce!.png ultimate let you pressure fragile, high-value targets, disrupting enemy positioning as you draw fire off less durable allies. Since every bounce of your Let&#039;s Bounce!.png ultimate yields Cell Division.png healing chunks, you'll also have the Cell Division.png sustainability you need to keep up the attack. If the opposing team making aggressive moves, you can opt to use the knock-up and slow from Let&#039;s Bounce!.png Let's Bounce! defensively, creating valuable space for the rest of your team to safely disengage. Whether you're initiating or counter-initiating, Zac has ample crowd control to keep your team out of trouble.

Zac Zac quickly tears through monster camps using a combination of Cell Division.png high-sustain mechanics and potent Unstable Matter.png area damage. With a little setup, Zac also has some of the longest range Elastic Slingshot.png initiation potential to date, enabling a variety of particularly devious ganks. Add in a powerful Let&#039;s Bounce!.png AoE ultimate and you've got one boisterous blob that's ready to lead the charge on the Fields of Justice.

Playing As Zac Zac
Playing Against Zac Zac


Ability Usage
  • Although all of Zac Zac's abilities cost a percentage of his current health, the cost is always compensated by picking up the blobs from Cell Division.png Cell Division.
    • In fact, because bloblets recover a percentage of Zac Zac's maximum health, picking up bloblets has a net healing effect which is increased at low health. Therefore, do not be afraid to spam your skills provided you can safely collect the bloblets.
    • However, do not overextend to collect a bloblet if doing so will expose you to crowd control, or more damage than you would heal.
  • Cell Division.png Cell Division allows Zac Zac to survive many situations that other champions could not.
    • For example, getting hit by Ignite.png Ignite at low health is fatal to many champions, but so long as Zac Zac can reach safety, he will be able to 'respawn' with half of his maximum health.
    • This also includes towerdiving. At maximum range of the turret, at least two of Zac Zac's blobs will land out of range, allowing him to survive and come back with over a quarter of his maximum health.
  • Stretching Strike.png Stretching Strike is a powerful slowing ability with a deceptively long range. Use this ability to lock down targets when pursuing or escaping.
    • This skill can be cast backwards (opposite to the direction Zac Zac is facing) without turning Zac Zac around. This makes it easy to use as an escape skill.
  • Unstable Matter.png Unstable Matter is a great AoE damage ability. Its percent damage makes it perfect for clearing jungle camps and gives Zac Zac strong sustained damage against enemy champions.
  • Spamming Unstable Matter.png Unstable Matter is a massive source of AoE damage in teamfights since it has a low cooldown and the percent damage is effective against champions.
  • The percent damage on Unstable Matter.png Unstable Matter actually makes it a worse skill for farming minions in lane and killing small jungle creeps because of their low maximum health.
  • Zac Zac can jump over walls with Elastic Slingshot.png Elastic Slingshot, allowing him to avoid warded areas. Therefore, this skill is invaluable both in setting up and performing ganks.
  • When initiating using Elastic Slingshot.png Elastic Slingshot, be sure to jump towards the back of the enemy team in an attempt to hit and focus the AD/AP carry.
  • The combination of Elastic Slingshot.png Elastic Slingshot and Let&#039;s Bounce!.png Let's Bounce! is an amazing initiation tool, which can easily stack a teamfight in your favor from the beginning.
    • When using Let&#039;s Bounce!.png Let's Bounce!, try to hit each member of the enemy team at least once to maximize the damage and number of knock-ups that the ability can achieve.
  • Although you cannot use Stretching Strike.png Stretching Strike or Elastic Slingshot.png Elastic Slingshot during Let&#039;s Bounce!.png Let's Bounce!, you can use Unstable Matter.png Unstable Matter. Take advantage of this to maximize Zac Zac's damage output.
    • Even when building very tanky, Zac has surprising damage output in teamfights. The enemy team will either be forced to focus you (allowing your ADC and APC to wreak havoc) or else take lots of damage from Zac Zac's abilities.
  • Using Let&#039;s Bounce!.png Let's Bounce! will result in the dropping of four blobs from Cell Division.png Cell Division, which you can pick up for a whopping amount of your maximum health (even more with Spirit Visage item.png Spirit Visage)
    • This makes Zac Zac's a deceptively tanky initiator. You will likely lose a lot of health during Let&#039;s Bounce!.png Let's Bounce!, but you can gain most of it back so long as your resistances are high. As such, Zac Zac effectively has two build paths: full tank and AP bruiser.
Mastery Usage
Item Usage
  • Randuin&#039;s Omen item.png Randuin's Omen is a strong item on Zac Zac for a tank build, since it provides health, armor, and useful active and passive effects.
  • Spirit Visage item.png Spirit Visage adds increased sustain, health, cooldown reduction, magic resistance, and no mana-related stats, making it perfect for Zac Zac.
  • For boots, your decision should be between Mercury&#039;s Treads item.png Mercury's Treads, Ninja Tabi item.png Ninja Tabi, or Boots of Mobility item.png Boots of Mobility. However, Boots of Mobility item.png Boots of Mobility should only be used if you need to be getting back to lane very quickly, or if you're jungling and need more mobility.
  • Warmog&#039;s Armor item.png Warmog's Armor should be taken to provide tons of health as well as very strong health regeneration effect. It is especially effective when combined with Spirit Visage item.png Spirit Visage
  • Rylai&#039;s Crystal Scepter item.png Rylai's Crystal Scepter works well even for a tank build because it provides a lot of health and gives utility and bonus damage.
  • Juggernaut item.png Cinderhulk can be useful because of percent health boost and area damage.
    • Sunfire Cape item.png Sunfire Cape is amazing, since it gives AoE damage, health, and armor, which all tanks need in order to be effective.
  • Locket of the Iron Solari item.png Locket of the Iron Solari is really effective on all tanks, since it gives health and magic resist, as well as an active that allows you to shield your entire team, making your strong initiation skills even stronger.
  • A Guardian Angel item.png Guardian Angel is a good item to rush on Zac Zac. Since the item synergizes well with Cell Division.png Cell Division he is granted a 'second life', which makes Zac Zac incredibly difficult to kill and adds extra turret diving capacity.
  • Rylai&#039;s Crystal Scepter item.png Rylai's Crystal Scepter is a core item for a bruiser build. The slow, health, and AP all work perfectly with Zac Zac's damaging style, plus this item functions well in combination with Sunfire Cape item.png Sunfire Cape or Juggernaut item.png Cinderhulk.
  • Abyssal Scepter item.png Abyssal Scepter can be used to provide some penetration and magic resist to help in dealing with enemy mages.
  • For boots, you should use Mercury&#039;s Treads item.png Mercury's Treads, Ionian Boots of Lucidity item.png Ionian Boots of Lucidity, or Sorcerer&#039;s Shoes item.png Sorcerer's Shoes. The decision is based on whether you want survivability, cooldown reduction, or magic penetration.
  • Like with the tank build, Randuin&#039;s Omen item.png Randuin's Omen is recommended, as it provides armor and health to deal with the fact that Zac Zac needs to be really close to deal damage.
  • Rabadon&#039;s Deathcap item.png Rabadon's Deathcap is not recommended, but can be used if more damage is necessary.
    • Consider substituting it with a Warmog&#039;s Armor item.png Warmog's Armor for more survivability.
  • Zhonya&#039;s Hourglass item.png Zhonya's Hourglass is a viable purchase because of the survivability it provides as well as the large amount of AP, not to mention the stasis active.
  • Magus item.png Runic Echoes offers ability power and movement speed, making it a very efficient source of damage and mobility for Zac Zac.
  • Liandry&#039;s Torment item.png Liandry's Torment is basically a must on him, since he is so heavily based on health and that penetration will make his percent damage on Unstable Matter.png Unstable Matter even more potent. This is a particularly effective pick in combination with Rylai&#039;s Crystal Scepter item.png Rylai's Crystal Scepter.
  • Try not to waste gold on items with mana or mana regeneration components, as these are wasted on Zac Zac.
  • Any slots not taken up by AP items should be slotted to increasing survivability, since Zac Zac needs to be so close to enemies to effectively deal damage.
  • Spirit Visage item.png Spirit Visage is highly effective on him, and it is recommended that you pick it up regardless of build path, unless there are no champions on the enemy team that do significant magic damage. It is extremely strong because Spirit Visage item.png Spirit Visage's passive gives Zac Zac more effective healing due to the healing from Cell Division.png Cell Division being partially negated by the health cost of his abilities. E.g. you're at 50% HP, you cast an ability which puts you to 48%, and then you pick up a blob which heals to up to 52.8% (rather than 52% without the Spirit Visage item.png Spirit Visage which is an effective healing increase of 40%).
  • Zac Zac heals from the blobs that separate from him. You can crush them by stepping on them.
  • Kill all of Zac Zac's bloblets when he splits apart to prevent him from reforming.
  • Silences, roots, stuns and knockups will all interrupt the charging of Zac Zac's Elastic Slingshot.png Elastic Slingshot.
  • All forms of crowd control are especially effective against Zac Zac, since without mobility to allow him to collect his healing blobs from Cell Division.png Cell Division he will, therefore, chop down his own health.
  • Building a Morellonomicon item.png Morellonomicon against Zac Zac can be extremely effective, since it significantly reduces his healing.
  • Zac Zac needs to be very close to you in order to deal the majority of his damage, which makes kiting a very viable strategy.
  • Cell Division.png Cell Division has a very long cooldown. Popping this before a teamfight or other major engagement can cripple his effectiveness.
    • Be sure to keep an eye on when this is available, as it will allow you to more accurately determine whether you can win a 1v1 with him. Click Zac Zac before a teamfight to see if his passive is active.
  • Even though they take reduced AoE damage, you can still easily destroy all of Zac Zac's blobets by using a mage with a lot of AoE damage. Champions such as Malzahar Malzahar, Brand Brand and Swain Swain can easily kill Zac Zac while Cell Division.png Cell Division is activated.
    • It may be helpful to wait to use AoE abilities against Zac Zac's Cell Division.png Cell Division until the blob chunks have come close enough together that all can be targeted at once.
  • Champions like Gragas Gragas, Janna Janna, Lee Sin Lee Sin, Tristana Tristana and Xin Zhao Xin Zhao can throw Zac Zac away when he uses Let&#039;s Bounce!.png Let's Bounce!, by using their own ultimate abilities.
    • Alternatively, champions with knock up CC available like Janna Janna or Nami Nami can keep Zac Zac from moving around a teamfight if used after Zac Zac activated Let&#039;s Bounce!.png Let's Bounce!. This can significantly reduce the effectiveness of the ability.
  • Zac Zac deals only magic damage with his abilities. As such, you can buy magic resistance to counter his damage.
