Playing against Katarina

How to counter and exploit weaknesses

1

Save a CC to interrupt her R (Death Lotus) — she's very vulnerable during the channel.

2

Avoid daggers on the ground: don't walk over them and stay away from where they land.

3

Katarina is weak before level 6 and in short trades without her daggers — punish her early.

4

Buy MR: her damage is almost 100% magic, even in on-hit builds.
