Masteries + Notes
Zac is the product of a Zaun experiment to manufacture a hexchem-engineered supersoldier – the Zaun Amorphous Combatant. Combining brute strength with limitless flexibility, he is a versatile juggernaut: a creative fighter who bounces over obstacles and pounds his foes into submission. Though he was created inside a weapons laboratory, Zac was rescued and adopted by two loving parents who raised him to be a kind and friendly child. As the years passed, he grew up to be a fierce hero, sworn to protect the ordinary, everyday people of Zaun.
Long ago, two Zaun scientists developed an organic substance that could withstand extreme conditions, spontaneously alter its biological structure, and generate tremendous amounts of kinetic force. As the scientists, husband and wife, watched the prototype grow from a spoon-sized droplet to a small blob, they noticed that their creation would respond to their presence. It sprung forward when they called and bounced when they sang. The couple began to see more than an experiment; they saw a small child, filled with affection and joy.
After testing the prototype one evening, the scientists placed the blob back in its cage. It slouched and shuddered in the corner, inconsolably sad. At that moment, the couple realized that their beloved creation wished for a free life outside the lab. They were struck by their conscience and could not allow the prototype to be used as a weapon. The husband and wife fled with the young blob, replacing its weapon designation – Zaun Amorphous Combatant – with a proper name: Zac. In a quiet neighborhood far from the cities of Zaun, the scientists raised Zac as their own child.
Zac was always different from the other children. None had his powers of strength and flexibility, so the couple taught him to tell right from wrong and to use his gifts responsibly. Thanks to the care and affection of his loving parents, Zac lived a peaceful, happy childhood.
That childhood ended when the Zaun laboratory finally found Zac. Unable to replicate the formula used to create the amorphous prototype, the laboratory’s staff never stopped searching for the scientists and their experiment. When they tracked down the family, they threatened to tear it apart. The staff abducted Zac’s parents and demanded that the couple assist in his capture and return. Seized by the fear of losing his freedom and his parents, Zac unleashed every ounce of his raw energy and mass for the very first time. He subdued his parents’ captors, sent the laboratory’s workers fleeing, and brought his loved ones home. From then on, Zac vowed to defend all ordinary lives threatened by extraordinary treachery and wickedness. Originally built to destroy, he now protects the innocent and the helpless.
“Even if you don’t have a spine, you still have to stand up for yourself.” -- Zac
Pros / Cons
Greater Mark of Ability Power
Greater Seal of Armor
Greater Glyph of Scaling Magic Resist
Greater Quintessence of Ability Power
Boots of Speed
Rod of Ages
Rylai's Crystal Scepter
Boots of Speed is a great starting item, because it gives you basic Movement Speed (+25) and it helps make a First-Blood chase at the start.
Health Potions are a great way to regenerate your health. Health Potions are used all the time, they are cheap and they can help you survive.
Sorcerer's Shoes are an upgrade for Boots of Speed, they give you more Movement Speed (+45) and +15 Magic Penetration for increased Magic Damage.
Rod of Ages is a nice item, good for a lot of champions. It grants you health (much needed for Zac), mana ( Zac has no mana, so not needed), Ability Power and a handy Passive. The Passive grants you 18 health, 20 mana and 2 ability power per minute. Bonuses cap at 180 health, 200 mana and 20 Ability Power. It comes in handy when you level-up, it heals you.
Rylai's Crystal Scepter is a great item, very good for Zac. It grants you a lot of ability power, a good Crowd Control and a lot of health. The Crowd Control slows the one who you hit with your spell by 35% for 1,5 seconds (15% for multi-target spells, damage over-time spells and spells with a cooldown below 3 seconds. Health is much needed for Zac because he is a health user. It is in a good combination with all of his attacks.
Enchantment: Alacrity is good for Zac because he is a little slow, so by buying Enchantment: Alacrity you gain more movement, which is usefull. If you don't want to buy this item, it's your choice.
Zhonya's Hourglass is a great item for any AP champion, it grants you a great amount of Ability Power, Armor and a great Passive which puts you into Stasis, which makes you invulnerable and untargetable for 2,5 seconds.
Abyssal Scepter is a good item. Grants you Ability Power, Magic Resist and a nice Passive, which reduces the enemy's Magic Resist so you do more damage.
Rabadon's Deathcap is a must-have item for any AP champion, because it grants you so much Ability Power and a great Passive which grants you even more Ability Power. It will boost your spell damage.
Cell Division (Passive): This ability is unique and powerfull. It makes Zac so sustainable that he almost doesen't need to recall. When you use Stretching Strike or Unstable Matter, Zac sheds a piece of himself and it can be retrieved to regenerate health and sustain him on lane or in jungle. The second part of his passive is when he dies, he splits in four goos and if they reach the the centre of the explosion, Zac is revived. The cooldown for the second part of thepassive is 300 seconds.
Stretching Strike (Q): This is a good ability, when you hit your enemies with it, they take damage and are slowed. When used, Zac sheds a piece of himself which can be picked up for restoring health. In combination with other abilities, it is very usefull.
Unstable Matter (W): This is also a unique ability which is very usefull and should be used all the time in fights. It is mostly used for healing, like Stretching Strike.
Elastic Slingshot (E): This is also (for the third time) a unique ability which is mostly used for initiating a fight or to gank. Zac channels this ability and by channeling he increases the range. It can interupt other channeling spells and can be interupted by moving.
Let's Bounce (R): This ability (for the fourth time) is unique and very usefull. Zac bouces four times, dealing damage and slows enemies who are hit already and Zac gains movement while it is activated. It can be used for chasing and getting kills (because of the Crowd Control) and for runing away.
Heal is a good choice for Zac because he needs health and sustain.
Ignite is a good choice because it damages enemies even more and you can get first blood by using Ignite.
Flash is also a great choice, it can be used for chasing and running away.
I haven't tried jungling with Zac yet, but when I do, I will make a jungle guide.
