Hey guys. I enjoy playing Diana and she is one of my main/favourite junglers and mid laners. Diana is a champion worth trying out and this guide should make it easy to start with her. Hope this guide is helpful and will help you be a better player in league.

Pros

• Strong Burst damage
• Easy to chase people down with Lunar Rush, Moonfall
• Strong defense with Pale Cascade
• Easy jungler to play
• Good ganks using combo Crescent Strike -> Lunar Rush
• Lunar Rush is instantly off cooldown if target had been hit with Crescent Strike
  

Cons

• Very squishy at start (rush Glacial Shroud)
• Ganks aren't great until level 6 when without Lunar Rush
• Focused often

Take Flash no matter what as it is good for escapes and reaching fleeing opponents.

Take Smite when jungling to clear camps easier

Take Ignite when going mid lane to secure kills

Take Teleport when in mid lane to be able to recall and get back to hold the lane quickly.

When jungling start with a Hunter's Machete 1 Mana Potion and 3 Health Potions,
When going mid lane take Doran's Ring and 1 Health Potion.
Take Boots after and a philosopher's stone if low on money while jungling.
As Diana is melee and many of her moves require you to get close to opponents so rush Glacial Shroud for armor and extra mana.
Depending on their team then go for Abyssal Mask (for magic resist) or Frozen Heart (for more armor.)
Get Rabadon's Deathcap for more ability power. Then Rylai's Crystal Scepter for some more health and AP also with some slows for chasing. Take Sorcerer's Shoes whenever and take a buff at end game. I usually use Furor for hunting people down or Homeguard if my team is doing badly and I need to get to the turrets quick to defend them.

Final build

Take Crescent Strike 1st in the case of mid lane.
Max out Pale Cascade early but take a point in crescent strike early and Moonfall just before your ultimate Lunar Rush. Max crescent strike next then finish buy maxing moonfall. Take ultimate points when available

Go Straight to
1. Blue buff (Ancient Golem) and try to take it smite-less with a leash from your lanes.
Then go down to
2. Red buff (elder Lizard) and take it quickly with smite.
Then move to clear
3. the Wolves,
4. then Wraiths,
5. then Big golem,
Gank while you have both buffs, and keep clearing the jungle as you wait for the buffs to re-spawn.
If there is no enemy jungler take their blue and red to save time and to pressure lanes with ganks.
GANKING:
As Diana it is better to wait until you are level 6 to gank as she can dash quickly, using Lunar Rush to end opponents. If your team is holding lanes well i suggest waiting until then.

Take all the ability power masteries in offense then reduced damage from monsters/minions for jungling, otherwise take either more points in offense or in defense.
