Smite is the bread and butter of a jungler, use it to clear, steal, and dominate with! It scales with spell vamp as well!

Flash can really help you control where you go, if you miss a E, you can still flash for the W and Q or the Ultimate that will help cc the team.

Other Options

Ghost can really stand on when you are using your ultimate with that ghost and accelerating speed from your ultimate. It can also be used to chase down with Q so you can ensure CCs. Very viable option

In a team fight situation, having ghost can sometimes take a huge edge over flash because with ghost and the movement increase, you can surely hit your ult on everyone on the enemy team, but having flash can ensure that you could definitely flash to the person you want to get to during early and mid game. Even in team fights, sometimes taking flash can result in a better situation than ghost. Overall Flash is better in all aspects of the game, but ghost is nonetheless a viable option.

Passive: Cell Division

Each time Zac hits an enemy with an ability, he sheds a chunk of himself that can be reabsorbed to restore 4% of his maximum health.
Upon taking fatal damage, Zac splits into 4 chunks that attempt to recombine. If any of these chunks remain after 8 seconds, he will revive with 10-50% health depending on the health of the surviving chunks. Each chunk has 12% of Zac's maximum health, and 50% of his armor and magic resistance. This effect cannot happen again for 300 seconds.


Explanation: Each time Zac hits an ability on ANY enemy, there will be a random blob that generates and heals you for 4% of your Max HP. When you die, you turn into four smaller blobs that come in from North, South, East and West about 500 range from where you died, if they survive their way back to the main body, you will revive with up to 48% of your max hp, depending on how much they had.

Q: Stretching Strike

Zac lashes out with an elastic punch, dealing 70 / 110 / 150 / 190 / 230 (+ 50% AP) magic damage to enemies in a line and slowing them for 20% / 25% / 30% / 35% / 40% for 2 seconds.

Range: 550
Cooldown: 9 / 8.5 / 8 / 7.5 / 7
Cost: 4% of current health

Explanation: This is a long range nuke with your two hands that deal magic damage and slow up to 40% at rank 5, it has a relatively low cooldown later levels and is spammable. Make sure you use it to chase or to kite.

W: Unstable Matter

Zac's body erupts, dealing magic damage 40 / 55 / 70 / 85 / 100 plus a percentage of their maximum health 4% / 5% / 6% / 7% / 8% (+ 2% per 100 AP) to all nearby enemies (max 200 damage against minions and monsters).

Cooldown: 4
Cost: 4% of current health


Explanation: Your bread and butter, it can be used during your ultimate, and can be spammed during your creep clearing. It is very strong when clearing global objectives and should be used on cooldown in team fights.

E: Elastic Slingshot

Zac faces the cursor and begins channeling. After channeling or after reactivating the ability he launches himself towards the target location, dealing 80 / 130 / 180 / 230 / 280 (+ 70% AP) magic damage to all enemies hit and knocking them back for 0.5 seconds. The range of Elastic Slingshot increases based on how long 0.9 / 1.0 / 1.1 / 1.2 / 1.3 Zac channels.
Can be cancelled by moving; refunding 50% of the health cost.

Range: 900 / 950 / 1000 / 1050 / 1100
Cooldown: 24 / 21 / 18 / 15 / 12
Cost: 4% of current health


Explanation: It works a bit like malphites ultimate, except you cannot move while you are channeling, and it knocks people up for only 0.5 seconds. Great for interrupts and has a huge range for initiation.

let's bounce

R: Let's Bounce!

Zac leaps into the air and begins to bounce on the ground, up to a maximum of 4 bounces. Each bounce deals 160 / 240 / 320 (+ 25% AP) magic damage to nearby enemies, knocks them up for 1 second, and slows them by 20% for 1 second. Enemies hit more than once take half damage and are not knocked up.

Zac gains an accelerating movement speed buff (20-50%) and 75% crowd control reduction while active (does not reduce Suppression). Zac can right-click to move while in the air. While active, Zac is unable to activate Stretching Strike or Elastic Slingshot.

Max Magic Damage to the same target: 400 / 600 / 800 (+ 62.5% AP)
Cooldown: 130 / 115 / 100
Cost: No cost


Explanation: This ultimate makes Zac beyond godlike in team fights, an moving blob that can bounce everyone up by moving around the fight while bouncing, you are able to use other spells like Unstable Matter but not Elastic Slingshot. You can accelerating movement speed for the duration and 75% tenacity. Fool proof AoE CC.

Unstable Matter is your bread and butter for clearing jungle, ganking, and best part it scales really well with opponent's HP. Making ganks top or on ganks extremely strong.

The reason why I believe Elastic Slingshot and Stretching Strikes are equal in value is because while Stretching Strikes gives you additional slow and more damage, being a lower cooldown. Leveling Elastic Slingshot increases the ganking viability by decreasing cooldown while increasing the range of the slingshot, which makes it a much preference option and depending on where you are ganking and what your plan is.

You are a jungler, start with this.







Move onto these items for your early game, Spirit Stone helps you clear extremely fast, while Kindlegem gives CDR and health that is very pleasant for Zac.

Everything about spirit visage is good for Zac, the CDR, health, and the extra healing. Even the Magic resistance to make him more tanky, HOW DO YOU NOT GET THIS?

Since his damage is weak, but his aoe damage makes him phenomenal, Sunfire Aegis gives him not only damage, but armor and health. GO FOR IT.
Everything that he uses scales by HP, get Warmogs on this guy like you'd get it on Mundo, but you don't have to rush it at all.

Between these three items, its very situation which one you get first, although I believe that generally camping mid and getting spirit visage is good, getting sunfire cape is also a very pleasant idea. Even more, warmogs gives you the unbelieveable sustain that you will ADORE.

Locket seems to be the current meta of jungle s3, it's stacks match well with Zac's, and synergizes well with his passive and spells to use as a bait.

This item is rather good for Zac, however, for a 1300 gold difference compared to spirit stone for 10% cdr, 20% spell vamp (1/3rd because all of Zac's abilities are aoe) and 50 AP. I believe there are better options. It is a good option if you like to farm...A Lot.

This item works well with Zac's Stretching Strikes. If you do decide to get Rylai's Crystal Scepter it can scale amazing with Unstable Matter.
This item can prove to be quite godly for Zac, as he scales with AP and Health it befits him perfect. Using it to chase down your opponents, even if your Stretching Strikes can slow, this item won't fail you.

This item is always strong in team fights, which is where Zac shines, if your support doesn't get it. This item is STRONG.

This item has proven itself to be ridiculously good throughout season 3. If their team has a fed ADC, or their bruisers are just unstoppable, you can look into this to try stop their team while you are bouncing with that active.

If you don't get Mercury's Treads this is a good choice for the tenacity that you MAY need.

With all the magic pen runes and all the other magic pen items, you can reach 70 magic pen....Who needs AP when you can achieve 70 magic pen?! NO MITIGATION YO! Get this if you'd like that magic resistance and nobody else got it.

Rather odd item, but if your team has heavy on ap, its not a bad item to get, and synergizes well with Spirit of the Spectral Wraith

Health: 455 (+95)
Attack damage: 54 (+3.375)
Health regen: 12.5 (+0.55)
Attack speed: (+1.6%)
Mana: N/A
Armor: 14 (+3.5)
Range: 125
Magic res: 30 (+1.25)
Mov. speed: 335

Health is one of the most important stats that Zac wants, he casts his spells off his current HP, a bit like how Dr. Mundo casts his spells, except, he does it off Current Health 4% on each and every single spell, except his ultimate, let's bounce.

However, the best part of Zac is his passive Cell Division which gives him unparalleled sustain as a health based champion. While his spells cost Current Health 4% he heals by Maximum health 4% which increases to 4.8% with the item Spirit Visage.

So imagine a scenario where you just died, divided in 4 blobs, and they enemy has flee'd for his life away from the tower. Now, you don't need to back as it was a direct engage from a previous back. What to do? Well! You can directly enter your jungle and start clearing, why? Because everytime you use a spell that costs 4% of your current hp, really only costs you 2% of your maximum hp. Meaning you are effectively healing for the spells you are spamming. 4% - 2% = 2% healing on your spells. Don't forget, Unstable Matter only has a 4 second cool down, effective sustain at any stage of the game.

Wait, wait, wait, health. Let's put things into actually prospective. Let's take a mid game active health for Zac around 3000 HP. Let's throw him a Spirit Visage, since its one of his core items. In a initiation, he goes into the fight at full HP, pulls off his full combo, which effectively costs him 4% of his current health 3 times, which results in 0.96^3= ~88.5% = 2655 of his health left, excluding all the regen that he might have gotten since. Then he pulls off his ultimate, let's bounce which costs nothing to cast. Say he was hit to 50% = 1500 HP after casting all these abilities, and did not pick up the 7 blobs, 3 from the basic spells and four from his ultimate, during this time. He starts picking them up, which heals him for 7*4.8% = 33.6% = 1008 HP. Instantly, Zac is healed back up to 88.6% = 2658 HP in just a few seconds. WHAT IS THIS SUSTAIN, BURST HEAL?!





So after learning about how health works in general, you realize, God! Cell Division gives Zac SO MUCH SUSTAIN! So what if in clearing and team fighting, you were able to use more spells, have more blobs to heal off of, and most important do MORE DAMAGE. Well guys, that's I'm here to tell you. Spirit Visage is a Godlike item because everything about it, is ridiculously good for Zac. Not only does it give the desirable abilities of health, but magic resistance to increase the effective HP against magic damage. Increase healing capabilities such as Cell Division and spell vamp. Most important, it gives you cool down reduction to increase the amount of damage output you can do, and increase sustain during these team fights!

For this section, we'll focus more on your primary spell throughout the game, Unstable Matter. It has a base cool down timer of 4 seconds, and can be changed by cool down reduction 40% to 2.4 seconds. Compared to my current primary YOLO DIVE BUILD, which you are looking at either 34% with an elixir, or 39% with blue bluff, and doesn't waste any effective cool down reduction. Since you have 4 points in socery getting anything beyond 15% cool down reduction item decrease it's gold efficiency by a quite a margin.

Let's do some actual comparisons.

With 0% cool down reduction, you will be looking at this

Cool Down 0% 20% 24% 30% 34% 39% 40%
Seconds 4 3.2 3.04 2.8 2.64 2.44 2.4
Cast 40s 10 12.5 13.2 14.3 15.1 16.4 16.7

While the difference indeed exists, I believe it is minimal and cost ineffective to buy cost inefficient items just to increase 1 or 2 more Unstable Matter

Let's take 24% vs 34%, which 10% additional cool down reduciton is the most ideal choice without wasting any effective gold around buying. The typical choices Zac has are Spirit of the Spectral Wraith and an additional Kindlegem for Locket of the Iron Solari, which matches a respective 1300 gold compared to Spirit Stone and 850 gold for Kindlegem. Take solely cool down reduction, you will only gain 2 extra hits if you use Unstable Matter on cool down within a 40 second team fight, which is extremely unlikely, so most likely 1 more at max. Which makes rushing that extra 10% cool down reduction seem meaningless, although this doesn't factor in the health, spell vamp, and clearing speed and sustain from Spirit of the Spectral Wraith and Kindlegem.




Armor and Magic resistance are splendid stats for any tank, off tank, or even carries that just want that extra efficiency within a team fight, or a simple engage. Armor and Magic resistance works like this.

25 magic resistance → ×0.8 incoming magic damage (20% reduction).
100 magic resistance → ×0.5 incoming magic damage (50% reduction).
−25 magic resistance → ×1.2 incoming magic damage (20% increase).

A unit with 60 magic resistance has 160% of its maximum health in its effective health, so if the unit has 1000 maximum health, it will take 1600 magic damage to kill it.

This means, for someone like Zac who stacks health, the more armor and magic resistances you obtain, the more powerful and effective hp you have. That is why items such as Sunfire Aegis and Spirit Visage are core items for Zac because they help improve his tankiness whilst offering him incredible stats. If you feel that the enemy team has some over powered ADC, feel free to obtain that Randuin's Omen to tank him further, or even that Thornmail so he kills himself.




Ability power is the stat that effects how much damage your spells do throughout all of Zac's spells. However, since Zac does not have any significant AP ratios, with Elastic Slingshot scaling highest at only 70%, which isn't even a highly spammable spell. Hoarding lots of ability power is often a heavily wasted cost inefficient item.

However, for Unstable Matter 100 AP increases the health damage it does by 2%, which is quite effective. Compared to the effectiveness of a item such as Liandry's Torment it is only an insignificant number. Therefore, we have to conclude that it is not very effective.
