It's a very pretty looking guide. I would suddgest adding an alternative items chapter. Because Abyssal Mask and Deathfire Grasp are two items I have seen on a lot of Dianas. If this has any help +rep me

NO!You people don't understand,do you?
1st thing:Starting Cloth Armor to upgrade in Madred's Razors is a waste of money.Starting boots+3HP pots will do better job,or even starting Doran's Ring if you see that you will have a good leash.
2nd thing:You state that Diana is an assassin,but you build Nashor's Tooth which is completely useless on assassins.
3rd thing: Lich Bane way too late.
4th thing:No Tough Skin nor Bladed Armor ,WTF?
5th thing: Rylai's Crystal Scepter too late,it needs to be first major item.
6th thing:Because you're jungling,try maxing your W first,or at least put 2-3 points in it before you max Q completely.
7thi thing:YOU NEED MORE TANKYNESS.

Nice guide man! Im just not sure about Nashor's tooth . That item is more about clearing jungle mobs, its not usefull without good cc aggainst players. It should be like optional item, depended on team. Well, it just my opinion. :)

Still, great guide! Create more!

Great guide man. This is how i wanted my guide to look like aswell:)

If you Que solo with people with poor initiate i recommend Zhonya's Hourglass as mandatory as its awesome to Q-R-W-pop glass. This will be a brilliant initiate!

I was aswell considering the Tooth in the build, but i find it that the majority of DMG come from AP, and the melee dps is pathetic so Deathfire Grasp or another item with more AP would make you more deadly.

But i think you have an Excellent guide here, and i will most certainly try it out!

keep up the good work!
