Introduction

Heyy, I am Erknaite! I am Grandmaster, currently peaking 599 LP playing exclusively Zac with 63% winrate reaching Rank 4 Zac EUW. I have been playing League since Season 8, I have 4 million points on Zac and I strive to be the best Zac OTP in the world.

I made this guide due to a lack of updated guides on Season 13 and a big amount of requests from people wanting to learn Zac.

In this guide I will explain runes and item builds. However I won't go in depth with how to play Zac mechanically because he is not that mechanically demanding to begin with.

Season 14 Current Patch Peak

Socials
Twitch - I am striving to be a successful Twitch Streamer. Be sure to follow, my purpose is to make it educational and entretaining.

Twitter - Where I discuss about league, post memes and other stuff.

Youtube - This is going to be my channel where I will upload selected gameplay, work in progress currently.

Discord - My server where you can ask me any Zac related questions and talk with other members.

Aftershock

Aftershock provides you safety when you engage in providing you bonus Armor and Magic Resist when immobilizing enemies with Stretching Strikes, Elastic Slingshot or Let's Bounce!. Transcendence is important this season because of the lack of ability haste in the game, its passive also reduces your remaining cooldowns by 20% on takedowns which can come clutch every often in skirmishes and teamfights. Waterwalking is exceptional this season too because of the new Voidgrubs objective, there are a lot of fights in the river and its adaptive force is extremely strong since the recent changes to the rune, the movement speed is also very useful. Conqueror Conqueror is the best rune for Zac when the enemy team is quite tanky and has very little burst damage and excels in sustained damage as it provides you Ability Power when hitting abilities, and 8% healing based on your damage dealt. Enemy Team Example: Top: Ornn | Jungle: Hecarim | Mid: Sylas | ADC: Jinx | Support: Leona The only downside of this rune is that you lack the tankiness when engaging but shouldn't be an issue when picked in the right scenario.

FLASH Flash is Zac’s most important tool to guarantee game winning engages with your Stretching Strikes after landing Elastic Slingshot. Can also be used for Let's Bounce! + Flash combo to surprise enemies.

SMITEI think it's kinda self explanatory why you go Smite on jungle.

The Erknaite Build Template

I came up with this build template that anyone can use for Zac in their games with the objective of being simple, straightforward and successful.

It was made with the intention to balance all the stats you need against each type of team compositions with maximum efficiency. Item order can vary depending on your needs throughout the game







Early Core Items

Mosstomper Seedling Mosstomper Seedling provides shield and tenacity. It's a good pet vs teams with burst and/or CC. You don't need to buy Health Potion because Zac's clear is healthy enough and it's better to save that tiny bit of gold for your early spikes.

Dark Seal Dark Seal is the best item in the early game for Zac as it provides you free 55 AP when you reach 10 stacks which is fairly easy to do on a Tank like Zac that has very low deaths. You may ask, why is 55 AP that good on him? Zac has one of the highest AP ratios in the game specially on his Unstable Matter which has a 3% max HP per 100 AP ratio. You only sell the item when you buy your 6th item.

Bami's Cinder Bami's Cinder is a really strong component that provides you with a decent amount of health and clear speed. Look to upgrade it to Sunfire Aegis or Hollow Radiance.

Ionian Boots of Lucidity Ionian Boots of Lucidity are a must to rush after your finished your first item Zac scales exponentially with ability haste increasing your clear speed. more Haste = more Abilities = more Blobs = more Abilities = more Blobs ... which increases your damage and sustain significantly.

Armor Items

Randuin’s Omen Randuin's Omen is very effective vs Crit champions like ADCs and some Melee champions such as Yasuo, Yone and Tryndamere.

Thornmail Thornmail is very good vs Heavy Healing auto attack based champions and draintank items such as Blade of the Ruined King.

Knight's Vow Knight's Vow has similar stats to Iceborn Gauntlet but it's way cheaper, it's a good alternative when you need to enable a carry on your team as it provides them damage reduction and the damage they deal to enemies is converted as healing to you.

Magic Resist Items

Spirit Visage Spirit Visage is arguably one of the best items in the game for Zac as it provides you healing amplification which makes you almost invincible at Lvl 16 when your passive Cell Division spikes and your blobs start healing for 8% of your Max Health.

Abyssal Mask Abyssal Mask is extremely cheap and gives you up to 105 Magic Resist and up to 25 Magic Resist shred. It's overpowered right now. Although consider replacing it with Spirit Visage if you don't have any AP ally or if one of your allies already has Abyssal Mask because it doesn't stack with eachother.

Kaenic Rookern Arguably the strongest Magic Resist item in the game currently, even then, Zac prefers Abyssal Mask over it, consider buying it against 3+ AP comps where the enemy champions are ranged with a lot of burst.

Force of Nature Force of Nature provides you with a ton of magic resist and a decent amount of movement speed. Consider buying this against comps with heavy damage over time champions such as Brand, Cassiopeia and Azir

Health and AP Items

Liandry's Torment Liandry's Torment is a really good as a 1st item rush on Zac. Its burn helps with clear a lot and provides you with great damage early game.

Riftmaker Riftmaker is a good alternative AP option for Zac in long fights against tankier targets as it provides you with 10% damage amp and 10% omnivamp [100% effect in AoE] when fully stacked and it converts your bonus HP into AP.

Cosmic Drive Cosmic Drive is the best AP option when the enemy team is mostly squishy and can kite you easily as it provides you a lot of movement speed and ability haste.

Morellonomicon Consider buying Morellonomicon if the enemy team has non-auto attack based heavy healing such as Soraka, Vladimir and Aatrox.

Mejai's Soulstealer Mejai's Soulstealer is the cheapest AP option you can get, although risky, it has a very big reward giving you up to 145 AP at 25 stacks for only 1250 gold (considering you already have Dark Seal).

Void Staff Consider Void Staff as replacement on your AP slot if the enemy team is going to stack a lot of Magic Resist against you.

The Rabadon's Deathcap of the Tanks

Jak'sho, the Protean Jak'Sho, The Protean is insane on Zac as it provides health and a lot of Armor and Magic Resist with its 30% resistances amplification! It's the equivalent of Rabadon's Deathcap for Tanks.
