Just finished doing a massive change to this build. Now does more damage at all points in the game!

I am planning on continually evolving this guide both as other players realize just how great Jarvan can be at devistating lanes, and as I find better items for this build.

My current experiment is going to be replacing the Manamune with the Bloodrazor in the build, as well as to find another item that would work in-place-of the Manamune. I shall be updating once I find out the results. I would still like to thank the two of you for reading the whole thing (long sucker isn't it?) and giving advice.

Jarvan IV really doesnt need manamune he doesnt have mana issues, also its impossible to cap it as jarvan. If you play smart there is just no need. If you do struggle with mana just get blue buff if you have to buy a mana item get chalice but its really wasted...

I like getting Madred's earlier and not sure about Manamune, but overall great build +1.
