Alright chumps listen here. This is the way Diana was ment to be played. IN THE JUNGLE. I'm seeing all these players play her in lanes and watching them mana starve her and lose their lanes quickly. There are a few items you can do differently its all about your play style and if well you wanna build a bit more tanky or if you wanna laugh as you instagib that tank over there.

Honestly. Masteries can go any way. They are ment to fit your play style. I choose mine for more of a heavier damage output while still being on the slight defense side. Change em up and tell me how you did with them or use mine and see if it fits the way you play.

For marks I suggest Greater mark of Alacrity Why? Cause I said so! no but in all seriousness for higher attack speed of course to hit faster and stuff you know!

For seals I suggest Greater seal of Resilience Why? well simply put more armor less damage less time spent in town.

For glyphs I suggest Greater glyph of potency Why? Because shes an AP champ. More AP = More damage easily said.

For quintessence I suggest Greater Quintessence of potency Now if i really have to explain that one again... then you're not paying any attention.

Pros

+ Amazing burst damage
+ Can win most 1v1 fights and even some 1v2 fights if played right.
+ Her Pale Cascade ability makes her somewhat tanky.


Cons

- Rather squishy early game
- Ganking is rather difficult until 6
- very item dependent

For the time being until I can get some pictures up I will just do a directional guide of what I'll do in the jungle

First like most champs start with getting blue with the help of a leash.
Second kill the wolves.
Third wraiths
Fourth them freaking giants who talk **** about your mother
Then lastly get red buff.

Now depending where the game looks at this point is weather or not you gank.
If the enemy is overextended and you know you can successfully gank them without losing one of your own or even yourself for that matter then why the hell not! Gouge that bastards eyes out.

Darn blue buff wore out and your getting low on mana. Now let me ask you. Do they have a jungler? No.... Then why the hell haven't you gone into their jungle yet! If they do... well then hit that button labeled B once your oom *if i really need to explain what oom is then you sir do not need to be playing a mana champ* buy your next item... and get right back out there champ!

Diana is a very dangerous champ if played correctly and well like any other champ if shes fed your gonna have a very bad time.

Overall I honestly have no idea what I'm doing but figured I would give this a shot as it seems to work pretty well for myself and the very very very very few others that actually use her to jungle like shes ment to.

Give your opinions maybe tell me what can be changed. This is still only my first guide ever so tis probably lacking some major detail compared to the others.

Thanks for reading. GL n HF.

and for all those TL;DR OP.
