Against katarina, Katarina’s major power spike comes with finishing her first component item- giving her more sustain and more burst damage. Upon purchasing this item, Katarina will force more skirmishes and trades.

Once Katarina hits level 6, her kill pressure will intensify as her Ultimate R is a great tool and deals tons of damage. Respect her all-in once she hits level 6.

Katarina is really good in team fights. Make sure you lock her down with CC as soon as she engages so she cannot get a good Ultimate R off.
