Edit:6/7/2011 I will try and post a video of my gameplay in the laning phase of the game soon.

Edit: 6/9/2011 I think I will remake my guide and start fresh, if you have suggestions let me know, no tank items are needed

Orianna is a Dodgeball Captain who knows how to attack in style.

Orianna is uniquely her own, she is an amazing caster as well as amazing support.

Combos:

Q+W Great for laning it will harass the enemy champion enough but not make them want to run before its to late. Also good for slowing enemy team or speeding up your own team/minions.

Q+E+Q Great for destroying large minion waves as well as doing damage on the run.

Q+W+E Simply a good way to play safe when in a fight.

W+Q Great for speeding yourself up and catching up to people.

E+W Great for helping your team run or push.

Q+E+R+W For team fights mainly, you should try to use your E on your tank if none is available try to make your best decision.

Q+R+W Great to do good damage to the entire enemy team that was caught in her ultimate.

Gameplay: You must play from afar most of the time you should not be the one in the front line of a team fight. You must keep track of where your ball is at or else you are susceptible to most attacks even when casting you could lose track of where its at in a big team fight. You can also scout bushes and leave it in there as long as you stay close enough, which is extremely helpful as well as for safely scouting baron/dragon and potentially stealing the buffs.

Hard to lane against Heimerdingers as well as Ashes and Mordekaisers. Will update on this champion list as I come across them.

Doran's ring is an amazing first choice because it will give you the 45 AP at start and the mana regen necessary to lane longer longer. You will recall first to get boots around 400 gold unless you are dominating the enemy champion(s) in your lane. You should be doing well enough whichever lane you are in by now preferably mid in 5s or top in 3s you should be able to get Ionian boots once you get these your set for sometime til Blasting Wand. That will last til you are able to buy Rod of Ages.

Once you have obtained RoA your next item is a mages best friend: Rabadan's Deathcap. Once you have that you should have enough AP for some time. If the game continues to drag on then you next must start Lich Bane, it is an amazing item for Orianna because it can push a whole lane if she is alive after a team fight as well as do good damage to the ones who don't like to die easy by your abilities.

If the match is still going on then get Archangels Staff since you will have a little over 2000 mana by this point in the game which will have you around 600 AP. The final item is Rylai's Crystal Sceptor which will give some amazing slows as well as health. If the game lasts that long that is. If your doing well enough it could be over before you even finish Lich Bane at least in 3s that is. In 5s it can last up to Archangels, unless its a really close game.

Runes has the little magic pen that she needs as well as the 30 AP before Doran's Ring at the beginning.

Masteries are the standard 9/0/21

My skill sequence focuses on the Q & W at the start because it will give you the damage necessary to dominate most lanes. E is maxed last because the protective shield is nice so you can speed up friendly champions as well as yourself to save from ignite and maybe some incoming damage. It is not as important as the other skills because even with high AP you still give only a decent shield at max level.

Flash for the juking capabilities she has as well as getting that little edge to throw your ball a little bit farther.

Ignite helps for the life-steal champions as well as giving that little boost you need to finish someone off that can happen a lot with this girl.

[You really do not need ghost with her because of her W]

[You don't need clarity if you are playing smart]

[Exhaust you really don't need as well it could help but it wouldn't make much of a difference if you are playing her well enough]

In the early game its a bit hard to farm properly, but around level 8 you should be able to kill the magicians with your Q to your W, eventually you will be able to bring it back to you with your E and repeat process til minions are dead.

Since when do Dodgeball players attack people off the court? It's not allowed!

[Late game she can jungle a bit if she wants, but usually its not necessary]

Pros:

+Versatile
+Easy to escape with
+Pushes Great
+Team player
+Scouts
+No one likes to be hit by the ball

Cons:

-Squishy Early Game
-Skill Based

All in all she is an amazing champion that is uniquely her own, and if you don't read my guide all you should know is the combos which is in the first section highlighted green as well as experience through time. Follow my build and you should be fine.
