Orianna/Strategy

Skill usage

 * provides sight. Use it to check bushes before approaching to prevent ganks.
 * can be used on yourself to return the ball back to you quickly. Combine this with for quick harassment.
 * is a very powerful escape tool if Orianna has the ball. The combination of a movement speed boost and leaving a slowing AoE can be quite powerful.
 * can be used to drag enemies towards or away from you if you position the ball properly.
 * can create great synergy with all AoE skills, since it flings enemies towards the ball, so if you manage to catch the whole team, they will most likely be flung into the same place, making it a great opportunity to use skills like
 * can also be used interrupt channeling abilities, so try to save it for enemies that depend on channelled abilities, such as and her.
 * Using on an initiator is a powerful strategy; it gives the initiator an armor and magic resistance buff, a shield and it brings the ball into the battle. Just make sure not to get too far from it.

Build usage

 * Orianna is very mana hungry, so an early or  is a very good choice. This can also be remedied by buying 9 mana regen per 5s Seals and starting with a  during early laning.
 * Mana and survivability are necessary too, making, , , and good choices.
 * A good general rule for your build is: While you always want cooldown reduction, the better the game progresses for you and your team, the better it is to give Orianna an ability power build, and the worse the situation is, the more necessary the survivability build will be.
 * As a support/caster she benefits from ability power and cooldown reduction, like ,,, , , and.
 * If you have a team that consists of 3 or more casters, then is also a good choice. A tanky Orianna build with 35-40% cooldown reduction can lead to great survivability and lets you escape quite easy, thanks to  and, while still being able to support your team well.
 * Since all four of Orianna's abilities can deal AoE damage and scale with ability power, she can also be built as an extremely effective burst mage by putting more emphasis on ability power and magic penetration than cooldown reduction.

Countering

 * When playing as a mage champion, it is advised not to trade auto-attacks with, as her makes her auto-attacks stronger than yours.
 * Her main strength comes when you are inside her ball's AoE: keep out of it.
 * When uses her  or, try to avoid the ball's path as it will damage any enemy it passes through.
 * ball speed is fairly slow. Keeping your distance away from her ball will make it easier to dodge.
 * Standing behind minions will lower the damage from.
