Zac's AoE damage and self-healing skills provide him with a lot of flexibility on the battlefield. His 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 area damage and healing makes him a natural jungler. If you're partial to early game aggression, starting with an early lizard buff and spending your second skill point in Elastic Slingshot can open early gank opportunities. Since Zac's abilities have no mana cost, you might also consider donating an early golem buff to your AP carry. Once the action starts ramping up, you can make use of 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 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 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 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 mobility and strong crowd control make him a tremendous asset in team fights. With some patience and setup, you can use a fully channeled Elastic Slingshot to deploy Let's Bounce! from huge distances. Once you're in the thick of it, the additional bounces from your ultimate let you pressure fragile, high-value targets, disrupting enemy positioning as you draw fire off less durable allies. Since every bounce of your ultimate yields healing chunks, you'll also have the 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'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.
- Champion Spotlight
Zac quickly tears through monster camps using a combination of high-sustain mechanics and potent area damage. With a little setup, Zac also has some of the longest range initiation potential to date, enabling a variety of particularly devious ganks. Add in a powerful AoE ultimate and you've got one boisterous blob that's ready to lead the charge on the Fields of Justice.

- Recommended Items

- Ability Usage
- Although all of Zac's abilities cost a percentage of his current health, the cost is always compensated by picking up the blobs from Cell Division.
- In fact, because bloblets recover a percentage 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 expose you to crowd control, or more damage than you would heal.
- Cell Division allows Zac to survive many situations that other champions could not.
- For example, getting hit by Zac can reach safety, he will be able to 'respawn' with half of his maximum health. at low health is fatal to many champions, but so long as
- 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 over a quarter 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.
- Unstable Matter is a great AoE damage ability. Its 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 teamfights 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 small jungle creeps because of their low maximum health.
- Zac can jump over walls with 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, 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 teamfight 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 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 amount of your maximum health (even more with )
- Since Zac's bloblets count as minions, allies can to them to give Zac a brief period of invulnerability while reviving.

- is the most suitable keystone for Zac as he can accrue stacks quickly in the jungle with his relatively fast clears. The extra 300 health and sustain he gets from the mastery benefit his already high tankiness and sustain.
- Item Usage
- As a tanky initiator, Zac should purchase items that offer survivability. CDR is also extremely important since he is manaless and reliant on cooldowns for engage or peel. AP and Magic Penetration can also be considered if ahead or if his team needs more damage as Zac's AP ratios and base damage are quite high.

- Since penetration works so well in combination with Unstable Matter, is also 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.
- Zac more effective healing due to the healing from 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 which is an effective healing increase of 40%). 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 passive gives
- Zac heals from the blobs that separate from him. You can crush them by stepping on them.
- Kill all of Zac's bloblets when he splits apart to prevent him from reforming.
- You can use and on the bloblets.
- Silences, roots, stuns and knock ups 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 he will, therefore, chop down his own health.
- Building a Zac can be extremely effective, since it significantly reduces his healing. or against
- 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. 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 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's bloblets by using a mage with a lot of AoE damage. Champions such as Malzahar, Brand and Swain can easily kill Zac while Cell Division is activated.
- Champions like Gragas, Janna, Lee Sin, Tristana and Xin Zhao can throw Zac away when he uses Let's Bounce!, by using their own ultimate abilities.
- Zac deals only magic damage with his abilities. As such, you can buy magic resistance to counter his damage.
