Playing against Diana

How to counter and exploit weaknesses

1

Diana needs to land Q for the E reset — if she misses Q, she has to engage without a reset and loses a lot.

2

Spread out when Diana is in the fight — her R deals more damage with more nearby targets.

3

She's relatively weak in early game (pre-6) — harass her before she has her Q → E → R combo.

4

Buy a Zhonya's or Banshee's to survive her initial burst.
