NOTE: THIS GUIDE ONLY EXPLAIN THE GENERAL INFORMATIONS ABOUT JARVAN THE GUIDE BASED ON MY OWN EXPERIENCE This is my Jarvan Guide I hope u like it.This my custom Build I like to play him on AD.I've had good experience with it so Good Luck ;)

I recomment to takeand .If the enemy team has much CC u should take for a quick escape.

U can easy Farm with ur Passive and with a Q+E combo u can harrass the enemy and farm creeps.
If the enemy is ranged Use ur Q to farm it has an longe range and stay to the turret.

Ward near the Dragon to see early the enemey jungler.You can also ward in the Tribush.

In early Game try to farm much as you can you will need it in the late game.You can poke the enemey much with you Passive if you get early kills the late game will be easy to dominate.

In the Mid game you should take down the first top lane Tower to push your lane and going Mid / Bot to help your Teammates.

late in the game trying to run as many team fights as possible to achieve an ace and kill a tower / baron. Its easy to push with Jarvan so kill many Tower to get some Gold.

U can start the teamfight with your Ultimate and focus the Ad/AP Carry use the Q+E Combo to knock up the enemeys and use CC to slow them to pick and Kill for your Team.Pocke the enemeys with your AA [Autoattacks] with an Frozen Mallet. For the positioning stay in front to tank some DMG and then Cage the enemeys with your Ultimate to pick up a kill.

U can walk trought walls with your Q+E Combo to escape.
Farm with your Passive [Also in Farming/Warding].
Only a Team with lot of CC in Jarvans team is a good Team.

DONT DO THIS

If the enemeys has much CC then I recommend Tenacity Items like Mercury Treads .

For more lane stability, I recommend live items like Warmogs's Armor.

I only say better nerf Irelia....

You dont want to see and fed Yorick don't you?

Comon no one like Olaf on his Lane ;)
