Good day, In this guide you will learn the basics on Jarvan. For the most part he is an AD tank who can take a beating and still come out on top. This is my 1st guide and I hope you can stand with me with the poor quality. I will however upgrade it as time goes on.

So I'm not a maker of guides but because of the new patch i'v found Jarvan to be Quite good as a jungler. All you need to do is Kill the small adds (baby wolfs, wrath ect) 1st then work on the big one.


Start off to Blue you will need a leash. (Because of Riots new patch update the jungle is quite a bit more difficult) After blue go hit up them Wolves and now you should be level two. (If not go get wraiths)

Pro

Supper good at ganks

Levels well

You're a god late game

Cons:

Very Item depenant

takes a while to get use to ult and learning when and how to gank.

Jungle

Start off Cloth Armor and five Health Potion
Boots is next upgraded to Ninja Tabi if team is AD heavy or Mercury's Treads
Rush Aegis of the Legion then shortly there after pick up Runic Bulwark
Follow up with Giants's Belt then into Warmog's Armor
If team has a lot of AP pick up a Force of Nature
otherwise pick up some Attack Damage/Attack Speed by buying Black Cleaver
Or Trinity Force if you can afford.

Support

pick up Bootsand 3 Health Potion
Build Aegis of the Legion then shortly there after pick up Runic Bulwark
Make sure you are buying Sight Wards to help your adc.
Get tank by Warmog's Armor
as a support you wont have much kills so make sure you ignore AD and focus on becoming a brute.

Both

Guardian Angel is always a good pick.
Maw of Malmortius is nice but not ideal.

Play Video A bit out dated but it gives you the basics on what to expect while playing this champ.

As the royal family of Demacia for centuries, members of the Lightshield line have spent their lives waging war against any who opposed Demacian ethics. It is said that every Lightshield is born with anti-Noxian sentiment in his blood. Jarvan IV is no exception, even though he is the first Lightshield born to the age of League of Legends. As his forefathers had before him, he led Demacian troops into bloody engagements with Noxian forces, and on many occasions he has bled alongside wounded allies and fallen comrades. In his most crushing defeat, he was outmaneuvered and captured by a Noxian battalion under the command of Jericho Swain. This mistake nearly cost him his life at the hands of Urgot, but he was rescued by the Dauntless Vanguard, an elite Demacian strike force led by Jarvan’s childhood companion, Garen.
Those close to him believed that his capture had changed him. Xin Zhao was quoted as saying: "His eyes never seemed to look at you, only through you to something he could not look away from." One day, without warning, Jarvan IV handpicked a squad of Demacian soldiers and left Demacia, vowing to find "atonement". He began by tracking and hunting the most dangerous beasts and bandits he could find in northern Valoran, but he soon tired of such prey. Seeking something that only he understood, he ventured south of the Great Barrier. He wasn’t heard from again for nearly two years. After many had assumed the worst, he returned to glorious fanfare on the streets of Demacia. His Demacian plates were adorned with the bones and scales of creatures unknown. His eyes bore the wisdom of someone twice his age. Of the twelve soldiers who had departed with him, only two returned. In a tone as cold and steady as steel, he swore to bring the enemies of Demacia to their knees.

“There is only one truth, and you will find it at the point of my lance.”
―The “last words” of Jarvan IV at his failed execution

Kill stuff.
