PS: Sorry for bad english!

Hello, and welcome. I just tryed this one out (on hard bots^^) but in the end they didnt hit on me ^^

I have picked hp, armor and magic resist runer, gives u a small boost at early games.

I have picked out 0-21-9, for better mana/hp reg, exo and money. But you can try 9-21-0 if you prefer more dps.

I wanted frozen mallet in early game, slows the target, and give some dps and hp. After that i go for some heavy armor/magic resist. But last item you can choose between with Randuin's Omen (melee attackers) and Banshee's Vail (spell casters/magic attackers).

I max out E (Demacian Standard) for better defence while active, and W (Golden Aegis) for better defence "buff". And finaly, Q (Dragon Strike).

I choose Clarity and Flash.
Clarity for mana, found out in the hard way that Jarvan always gets om in the ends of fights in early games ...
You can choose between Flash and Ghost. You can easly use E+Q to get away, but if they have slowed you, flash is the "little extra"

And now the end of the little build.
I have tryed to talk about runes, masteries, items, skills and summoner spells. I hope this one works :)
Happy Jarvan Tanking!
