Diana is a medium early agency AP diver who wants to pressure Yone with her burst combo and deny his scaling trades.
Focus on using your Q + E + W burst to punish Yone before he can safely use his E + Q combo for trades.
Trading pattern
Initiate trades by landing Q then immediately using E to reset and follow up with W for burst.
Respect Yone's Q third cast knockup and his R for all-in threat; avoid trading when these are up.
If you miss Q, back off quickly to avoid Yone's counterattack; your all-in is predictable and punishable.
Danger windows
Avoid trading when Yone's Yone Q third cast knockup or Yone R displacement are available.
Be cautious when your E is on cooldown, as your pressure and mobility drop significantly.
Respect Yone's Yone E for trade extension and snapback; punish him only when it is used poorly or on cooldown.
Early game
Use level 3 power spike to trade aggressively with Q + E + W combo and shield from W.
Avoid extended trades if E is on cooldown since you lose pressure and can be punished.
Punish Yone when he uses E from a bad position to trade back hard or force him out of lane.
Power spikes
Major spikes: Level 3 unlocks your full Q-W-E burst with dash reset and shield; Level 6 R for all-in threat; first completed AP skirmish item increases damage.
Respect Yone's level 3 Q-W-E combo with E extension and W shield; his first back for attack speed also increases his threat.
Yone's R can instantly turn fights; keep track and avoid clumping near minions to reduce its impact.
Win conditions
Win by landing your Q + E + W burst combo when Electrocute is up to quickly chunk Yone.
Deny Yone's scaling by punishing his E usage and forcing him to farm under pressure.
Use your R at level 6 to set up kills or force Yone out of lane control in skirmishes.
Tip: For Diana vs Yone, read overview, trading pattern, and danger windows first for a fast Mid lane check.
