Jarvan IV Build
Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
How this build works
Plain and simple you need to start off well for this build to work out, if not then try a different build, however I believe starting off with a dagger and making berserker's grieves is a given for any build on him. The order I've given are the base items to start with and then build into, after you finish the inf edge work on the items in that order, getting rid of the your boots for the last phantom dancer, which will leave your end game move speed at 441 and 97% crit chance. If you're looking for crits early game I will generally get an Avarice Blade to help with gold gen and that's sold off somewhere near the end when I need room for the other items. This build is a very in your face build which is why I focus the q and e with one rank of w purely for the slow or the block of slight damage. end game you'll be critting for around 800 at max attack speed which leads you to ask "Well why not play Tryndamere?". The simple answer to that is that with this build Jarvan has much more utility with the attack speed buff for the team, the aoe slow and the knock-up with the q-e combo, not to mention 1v1 or even 1v2 with his ult is almost a guaranteed victory in the end game. Any comments or questions please feel free to comment and I'll get back to you all, and constructive criticism is always nice =)
