Hey guys, this is my brand new Diana guide. As you can see what I have right now is a build that works for a successful Jungle Diana. I will be adding more information over the coming week or so. Please try out the build (it works very well) and tell me what you think.

Cloth Armor and Health Potion
So although the cloth armor does not build into anything (unless you want your boots to become Ninja Tabi), it is a very good early-game item combination for jungling with Diana. You can (optionally) jungle Diana just as easily with Boots and three Health Potions.

Hextech Revolver > Will of the Ancients
Good, cheap early Spell Vamp and AP which allows you to, generally, successfully gank top or mid lane and come away with either a kill or assist. By later turning your Hextech Revolver into a Will of the Ancients you a) increase your AP by a further 30 AP (plus 30% from Rabadon's Deathcap and b) increase your ally's AP by 30 and spell vamp by 20% which allows you to provide support for your team mates.

Ionian Boots of Lucidity
Cooldown reduction allows you to spam your Q more often thus allowing you to harass enemies from a safe distance. Getting these before your Hextech Revolver is a viable option if you would prefer movement speed over AP in your early game.

Rylai's Crystal Scepter
This item is great in any scenario on any AP Melee DPS (Akali, Diana, Katarina, etc.) for four reasons:

1. Good amount of AP.
2. Passive slow makes it very easy to chase down fleeing enemies.
3. The 500 health is very handy.
4. There are two cheap AP items within the item build which allows you to get a little bit more AP most times when you are forced to recall.

Lich Bane
Lets face it - you need to mana and you need the magic resist.
