Diana Mid Full Guide [300k main]
Good day, Friends. Welcome to my Short Mobafire-styled post, to help you get that freelo :)<3 - As someone who has almost Half a Million mastery Points on her on 3 different shared accounts, I really wanted to share my tips on how you can play her properly. She's no the best pick for mid lane at the moment, however, If you can get that level 6 snowball started, you can solo-carry any game easily.
Pros:
- Burstiest Diver
- Naturally Tanky
- Hard to counter play, especially when fed
- Good roamer
- Amazing Splitpusher
Cons:
- Hard to play (Read below)
- Bad Laning Phase
- Mana Issues
- Good knowledge of Itemization required
RUNES: Flat AP Quints, Scaling HP Seals, Magin Pen Marks & Scaling AP Glyphs.
Masteries: 12/18/0 TL works fine, But I've found a much better success rate with 12/0/18 CotC to work much better - With Cotc, You win Early trades & can use your passive more in teamfights (Which deals more damage than thunderlords). Either one is Viable, chose upon your play style.
Spells:
is a must for obvious reasons.
If they have someone like akali, who won't be harassing you too oftenly.
is probably a better spell on diana right now, really good for that first early recall / Splitpush.
Very situational, Only take if they have a zed, or veigar etc.

BUILD: PLEASE READ ----- DIANA DOES NOT BUILD GLASS CANNON. If You're building Full AP DIANA, You're doing it Wrong.
START -

FIRST ITEM -
Generically. You can also do
or
situational, or even
if you want to skip roa badly. If you are skipping mana item, take dorans blade. You'll be fine without a mana's item generally speaking, however roa provides really good stats on her.
BOOTS -
- You can also go
or
If you're behind / if they have full AD team for example, you can you tabi. dont take any other boots on her, including cdr boots.
3rd ITEM -
is usually always your 3rd item. If you've decided to build it first, you can skip this and build your defensive item next
4th ITEM -
or
- Completely up to you. You can also build
here, and build your defensive item as ur 5th item (only if you're ahead)
5th -
read above
6th - 
If you've decided to Go Zhonyas/Nashors as a first item, and you have an open slot, you can build
/
- I recommend only building lich if you're really ahead. if you have an open slot, it's important to throw in a tanky item in there (It will prove to be useful, trust me).

Q: Why is diana hard to play?? I thought she was Easy?? A: People say she's easy out of the frustration. Yes, Her combos easy to land. That doesn't make her easy. She becomes easy when you master her and work around her flaws (early game, mana issues, etc).
But How Do I play Diana?
Q>R>W>E>Q(optional)>R>AA>AA>AA>AA>AA>AA>AA dead. this is why, boys and girls, you take
on diana. I've heard people cry about how its a horrible item, and that you should be building burst on her. lol. if you're building diana as a glass cannon like akali, you're making a huuuuuge mistake. Diana is not akali. she is not an assassin. her Passive and her W means that she can build quite tanky, and still dish out a ton of damage. especially when taking Cotc.
IMPORTANT NOTE FOR PRE 6 - Try to play safe. Poke with your Q. A good way to trade is stacking up your Passive, Then when your Passive is up, You Walk up to the enemy, W, Q, AA. Your AA will do enhanced damage because of your Passive, and your W will ensure that you outtrade them
When you hit 6 - Playing diana is all about knowing when and when not to go in. Firstly, Never EVER engage with your R. Always make sure you land your Q first, otherwise you will lose a ton of damage (unless theyre low of course). Even if you Hit your Q, think twice about going in. A good way to get a snowball started, is constantly Poke with Q. Once you've hit your Q around 2~3 times, you can Q them again and then go in for a full combo. They should be low enough for you to kill them. Try not to combo them if theyre at full health, there's a risk that they can outtrade you. If you are going to do this, Retreat right after you go in. Dont wait till your Shield dies out,
How low should they be before I engage? - Once they've lost around 25% health, you can combo them (assuming you're on full health) - and usually come out with either a very successful trade, or a kill. Dont be afraid to stay in for a passive proc. Always always proc your passive when going in for a combo, even if it means staying in longer (unless you're putting yourself in serious danger)
Diana is all about decision making. Knowing her mechanics is one thing, Knowing how to play her is another. All in all, she's a pretty good champion, counters a ton of mid laners, and can potentially be a pretty good pick when played correctly.
replace void with
), I would only use mana on W just to be able to CS with less harass, and the amount you spam Q early will depend on how difficult the champion matchup is and how competent your opponent is on avoiding Q.

and then 2 defensive AP items or 2 tank items. Works like a charm with anyone that isn't a tank. For tanks you gotta add
