Playing against Orianna

How to counter and exploit weaknesses

1

Watch the ball's position: if it's close to you, move away to avoid the R (pull).

2

Orianna is immobile and relies on her positioning — assassins who can gap-close punish her well.

3

Her R is powerful but has a small radius: spread out so she can't pull everyone.

4

If Orianna E's an engaging ally, expect the R when that person dives.
