Kill Windows and All-In Timing

Diana needs the enemy below roughly 60% HP for a clean kill without burning summoners — less if they have MR items. Above that you're trading, not killing. Learn the difference.

Dashes and blinks break your second E. If the enemy has an escape on a short cooldown, you need to bait it before jumping. Walking up aggressively with Q often forces the panic flash you need.

After you force flash in a trade, you have a 5-minute window where the kill is much easier. Track it. That window is when you should be looking to roam or fight again.
