Champion Background Strategy Skins & Trivia

Skill usage

  • Although all of  Zac's abilities cost 4% of his current health, the cost is always compensated by picking up the blobs from  Cell Division.
    • In fact, because bloblets recover 4% of  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 put you in danger of enemy damage or CC.
  •  Cell Division allows  Zac to survive many situations that other champions could not.
    • For example, getting hit by Ignite at low health is fatal to many champions, but so long as  Zac can reach safety, he will be able to "respawn" with 50% of his maximum health.
    • This also includes tower diving. At maximum range of the turret, at least two of  Zac's blobs will land out of range, allowing him to survive and come back with 30% of his maximum health.
  •  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 is facing) without turning Zac around. This makes it easy to use as an escape skill.
  •  Unstable Matter is a great AoE damage ability. It's percent damage makes it perfect for clearing jungle camps and gives Zac strong sustained damage against enemy champions.
  • Spamming  Unstable Matter is a massive source of AoE damage in team fights since it has a low cooldown and the percent damage is effective against champions.
  • The percent damage on  Unstable Matter actually makes it a worse skill for farming minions in lane and killing the small jungle creeps because of their low maximum health.
  • Zac can jump over walls with  Elastic Slingshot, allowing him to avoid area with a Sight Ward in them. Therefore, this skill is invaluable both in setting up and performing ganks.
  • When initiating using  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 and  Let's Bounce! is an amazing initiation tool, which can easily stack a team fight in your favor from the beginning.
    • When using  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 or  Elastic Slingshot during  Let's Bounce!, you can use  Unstable Matter. Take advantage of this to maximize  Zac's damage output.
    • Even when building very tanky, Zac has a 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's abilities.
  • Using  Let's Bounce! will result in the dropping of four blobs from  Cell Division, which you can pick up for a whopping 16% of your maximum health (19.2% with Spirit Visage)
    • This makes  Zac's a deceptively tanky initiator. You will likely lose a lot of health during  Let's Bounce!, but you can gain most of this back so long as your resistances are high.

Build usage

 Zac effectively has two build paths; full tank and AP bruiser.


  • Randuin's Omen is a strong item on  Zac for a tank build, since it provides health, armor, and useful passive effects.
  • Spirit Visage adds sustain, health, cooldown reduction, and magic resistance, all of which benefit Zac greatly.
    • Since Spirit Visage gives cooldown reduction and no mana-related stats, making it perfect for  Zac.
  • For boots, your decision should be between Mercury's Treads, Ninja Tabi, Boots of Mobility.
    • 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'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
  • Rylai's Crystal Scepter works well even for a tank build because it provides a lot of health and gives utility and bonus damage.
  • Spirit of the Ancient Golem can be useful because of the tenacity, CDR and health.
  • Sunfire Cape is amazing. It gives AoE damage, health, and armor, which all tanks need in order to be effective.
  • 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 is a good item to rush on Zac. Since the item synergizes well with Zac's  Cell Division, he is granted a "second life" which makes Zac incredibly difficult to kill and adds extra turret diving capacity.


  • Rylai's Crystal Scepter is a core item for this build.
    • The slow, health, and AP all work perfectly with  Zac's damaging style.
    • This item functions well in combination with Sunfire Cape.
  • Abyssal Scepter can be used to provide some penetration and magic resist to help in dealing with enemy mages.
  • For boots, you should either use Mercury's Treads or Sorcerer's Shoes. The decision is based on whether you want survivability or magic pen.
  • Like with the Tank build, Randuin's Omen is recommended, as it provides armor and health to deal with the fact that  Zac needs to be so close to deal damage by comparison to other AP's.
  • Rabadon's Deathcap is not recommended, but can be used if more damage is necessary.
    • Consider substituting it with a Warmog's Armor for more survivability.
  • 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 active effect.
  • Deathfire Grasp can be effective on  Zac since it gives him a lot of ability power and a decent amount of cooldown reduction, which allows him to spam  Unstable Matter more quickly and increase his damage output.
  • 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 even more potent. This is a particularly effective pick in combination with Rylai's Crystal Scepter.
  • Since penetration works so well in combination with  Unstable Matter, Void Staff is a viable pick.
  • Try not to waste gold on items with mana or mana regeneration components, as these are wasted on Zac.
  • Any slots not taken up by AP items should be slotted to increasing survivability, since  Zac needs to be so close to enemies to effectively deal damage.

Other notes

  • Spirit Visage is highly effective on him, and it is recommended that you pick it up regardless of build path.

  •  Zac heals from the goo that separates from him. You can crush the goo by stepping on it.
  • Kill all of  Zac's bloblets when he splits apart to prevent him from reforming.
    • You can use Ignite and Smite on the bloblets.
  • Silences, roots, stuns and knockups will all interrupt the charging of  Zac's  Elastic Slingshot.
  • All forms of crowd control are especially effective against  Zac, since without mobility to allow him to collect his healing blobs from  Cell Division and he will, therefore, chop down his health.
  • Building either a Executioner's Calling or Morellonomicon against  Zac can be extremely effective, since they significantly reduce the amount that he can heal.
  •  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 has a very long cooldown of five minutes. 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.
