Katarina can farm effectively early game with Bouncing Blade but is melee so needs to be careful during the laning phase.
Don't initiate team fights with Death Lotus. Instead let your team initiate and then come in to the middle of the enemy team with Death Lotus.
LoL Katarina players could find her to be a dynamic champion to build out properly. You will see that her build changes when she is up against either diversified or homogenous team compositions, meaning you shouldn't select the same Katarina build every round of League of Legends
The most essential items to incorporate into your champion's build are: Hextech Rocketbelt, Rabadon's Deathcap, and Lich Bane. Those who included these items in their gear had a much higher win rate than players who utilized other Katarina builds. Moreover, if you are facing a mixed enemy team arrangement, you should really consider grabbing her the Domination, and Resolve runes. In recent matches, she won the greatest fraction of her matches when equipped with these runes.
