Lore: Centuries ago, an ancient water-dwelling race built a hidden city beneath a mountain in the sea. Though these creatures had their enemies, the city was an impenetrable fortress, and, in the safety it provided, they grew complacent. Fizz, however, harbored a curious spirit that could not be satisfied living so cushioned a life. Unable to resist the allure of danger, Fizz had a habit of sneaking out of the city to look for trouble. In his many adventures he grew to be a powerful fighter with a keen resourcefulness that let him skirt danger with clever ease. One day, Fizz returned to find the city abandoned: his people had vanished, leaving Fizz without a clue to explain their disappearance. With nothing left in the city to keep him, Fizz salvaged an enchanted trident from the ruins and set out alone.

For years, Fizz wandered the ocean, using the skills he'd learned during his adventures as a young boy to survive. Finally, Fizz discovered the port of Bilgewater. He was fascinated with the existence of life above the water and could not resist exploring the island. In his endless curiosity, Fizz inadverently meddled in the affairs of the humans who lived there and his presence did not go unnoticed. His mischief angered many residents who eventually sought to capture or kill him. Fizz found himself cornered, and he prepared to return to the sea despite the fondness he'd come to hold for Bilgewater. As he stood at the docks, a massive dragon-shark attacked the port. Fizz defeated the beast, using his resourcefulness and knowledge of the creatures' weaknesses to his advantage. Having earned the gratitude and respect of the humans, Fizz decided to stay in Bilgewater. He joined the League of Legends to further serve his new home.
''Fizz makes even the saltiest sailors of Bilgewater look like drunken landlubbers in a fight. Good thing he's on our side.'' -- Miss Fortune, the Bounty Hunter.

For runes i take :

Greater Mark of Desolationx9 ; Ur AD Fizz, youll need Armor Pen.
x9 ; Protects u from enemy ganks and gives u extra armor aggainst auto hits.
x9 ; u ask why ? easy.. i play AD Fizz cuz hes super strong since u can activate and gain additional Damage so u need to give that skill some bonus dmg.
x3 ; same here as with the glyphs.

For masteries i take 0/21/9.
U need those full tank masteries since ur Melee and oce ur opponente get that ur dealing great damage, theyll focus u and it really helps u in teamfights.
U could go 21/0/9, too, but i prefer the other one, cuz it makes u offtanky in lategame.

The skill sequence is easy.

w -> q -> w -> e -> w -> r ..
from then on max ur w-skill first, then q-skill at last e-skill.
Dont forget to skill ur ultimate everytime ur able to, at lvl 6, 11 and 16.

Ur AD Fizz takes a massive anmount of dmg from ur w so make sure to max it first.
Secondly ur maxing ur q-skill since it makes ur opponent almost impossible to get away, u can use it as an escape tool aswell, too.
Last ur maxinr ur e-skill, in my opinion its not a that much needed skill, on AD Fizz he deals almost no dmg, u rather use it as an escape tool to hop over walls or evade skills like Karthus, Lux or Caitlyn ulties.

For Items u start with lvl 1 boots and 3 potions.
First time u go back, try to get a . It gives u a massive anmount of attack speed which matches perfectly with ur w activated.
From now on, try to get then Berserker`s Greaves.
Next Item should be a since ur AD Fizz, u got ur attack speed, ur w but still need some extra damage. After that, u build it up to .
As soon as ur BT got nearby full stacks, youll do awesome dmg in 1on1, thats why enemies will focus u from now on.
Try to get a next, then get , it will give u the sustain u need.
To get even more dmg and to become a nice dmg dealing off tank, get Atma`s Impalernext.
Your last item should be and if u come that far, build a to give ur dmg the crown.

For summoner spells i take and .

Maybe ull be asking now, why not take instead of Heal?

The answear lies within the Champ ur gonna play, since u got your e-skill, theres no need for u to take Flash. U can jump over walls every few seconds, so u can take a summoner spell thats even more use to u and ur team.

Another option might be instead of heal, i think it depends on what ur opponents get in team.

Coming up soon..

So its still the question, why play Fizz on AD, while all of his skills scale with AP only ?

In my opinion, both strategies are very nice and do very nice dmg.
But other than AP Fizz, ull do constand dmg and u dont need so go out of tf´s as ur skills are all on cd, since ur not really using your skills to make dmg, u only activate ur w-skill and ur ultimate.

Now the pros and cons.

Pros :

Constant dmg.
Great mobility.
Ur an excellent tower diver.
Enemies wont escape u with Frozen Mallet.
Easy to land ultimate.

Cons :

Ur still Melee.
Laning phase / early game will be bit hard.
Without farm, ull just suck.
Once ur exhausted, ur useless.
