Welcome to my first Mobafire build.
This builde its about Diana i start to play her since she come out.
I am fokusing on mid laning u can play her also top and jungle but I have never try her jungle and mid makes more fun then top.
I hope this guide is usefull for you.
Comments are welcome and if my english is bad I am sorry.

Pros:
- strong shield
- fun to play
- Great Damage
- Hight Mobility
- No cd on ulti
- Assasine,Mage,Jungler,Fighter
- has a pull


Cons:
- not much Damage before lvl 6
- no escape skill
- often focused in teamfights
- often banned in ranked
- In Normalgames sometimes picked

I will explain why I choose this items later
I start with Boots of speed Boots of Speed and 3x Heal Potions or you can also start with dorans ring.
with my first recall i try to buy 2 or 1 dorans ring and a Kage's Lucky Pick.
Then Abyssal Scepter for the magic resistance u need if u are against Talon then build first Frozen Heart.
After you build this two items you buy Giant's Belt for the hp u need and then Rylai's Crystal Scepter.
Then u need some ap for this buy Rabadon's Deathcap.
And after all these items Guardian Angel.

I choose Abyssal Scepter for the ap u gives, Magic Resistance and the passive because u wont have much place for Magic Pen. so take this.
Frozen Heart .. I love this item on Diana 99 Armor, 500 Mana 20% CDR (if u fail your Crecant Strike) and then 20% Attackspeed reduction nice against an fed ad carry.
Rylai's Crystal Scepter ap, Health and now you can slow Attackspped and Movementspeed.
You need some more Damage so take Rabadon's Deathcap.
Your last item is Guardian Angel Armor, Magicresist. and a second Life <33.

So why the hell i take so much Mobility ?? You don't have much escape skills well you don't have 1 so buy Mobility.

There isn't much to say Lunar Rush > Crecent Strike > Pale Cascade > Moonfall

Ulti first like always. Crescent Strike for Damage and lower CD for your ulti. Pale Cascade for some mobility and it do much Damage. Moonfall use it always after you used ulti on the enemy carry for pullng to the team .

Combos : Crescent Strike ulti if u get him Moonfall Pale Cascade Crescent Strike ulti if need.
If you didn't get him then go back or if he got low hp and u need only 1 ulti and he die so use it.

I take Flash and Ignite but Ghost and Clarity or Teleport but be sure you have an escape skill Ghost or Flash.

Now why :

Flash : For escaping fights or ganks.
Ignite : Some true Damage if they flash out.
Ghost : For escaping fights or ganks.
Clarity : Diana is gettin fast out of Mana its nice for laning
Teleport : For defend your own lane if u are ganking, ask your Teammates if they could ward the lane for fast ganking.

Early : Stay at your lane farm till you have 950 gold and dont fight before you are lvl 6. If your enemy dont let u to farm ask your jungler for early gank maybe after blue. After lvl 6 you can start ganking other lanes and ask your jungler for the blue bacause you are often out of mana.

Middle : Start to play in team go take dragon ,steal blue or ganking and don't forget to farm for your mobility in the late game.

Late : Now the teamfights are starting and it will show who can play better together and don't play solo. Focus carry and never forget your Mobility if u get focuse and you are dieing to fast so buy Guardian Angel before Rabadon's Deathcap. Take Baron before the enemys take it.

So all in all play safe, farm well and buy Mobility and never miss Crescent Strike ,help other lanes if they flame and don't fail because no1 can be in evry game the best!!!

i hope it helped you and cya Beotes
