Katarina vs Diana

Updated May 31, 2026

Overview

Katarina has low early agency and lane pressure versus Diana's medium pressure and burst potential.
Focus on surviving early trades and punishing Diana when her Diana Q or Diana E are on cooldown to prevent her from all-inning.

Trading pattern

Trade around dagger placement and only commit when Diana's Diana Q or Diana E are on cooldown.
Use E to engage or reposition after Diana uses her mobility, punishing her cooldown downtime.
Avoid forcing trades without dagger setup or when Diana's shield (Diana W) is active, as it reduces your burst effectiveness.

Danger windows

Diana is dangerous when Diana Q and Diana E are up, enabling her burst and mobility.
Avoid engaging when Diana's shield (Diana W) is active as it mitigates your damage.
Be cautious channeling R if Diana's crowd control (Diana R) or burst combo is available to interrupt you.

Early game

Avoid engaging before level 3 when Diana unlocks her Q-W-E burst combo with shield.
Use cautious dagger setups to poke and create escape routes without overcommitting.
Respect Diana's ability to trade aggressively when her Diana Q and Diana E are available, especially with Electrocute.

Power spikes

Katarina's major spikes are level 3 dagger combo, level 6 R all-in, and first completed burst item.
Respect Diana's level 3 Q-W-E burst with shield and level 6 Diana R for all-in threat.
Both champions scale with item spikes, so early kills and resets favor Katarina's snowball potential.

Win conditions

Survive early lane pressure and punish Diana's missed Diana Q to create kill opportunities.
Use dagger resets and skirmishes when Diana's crowd control and mobility cooldowns are down.
Roam effectively after pushing wave to snowball other lanes and leverage Katarina's high mobility and resets.
