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 character to build out properly. You'll find that her build changes when she is playing against either diversified or highly focused team compositions, demonstrating you shouldn't take the same Katarina build every game of League of Legends
The most critical items to use in your champ's build are: Hextech Rocketbelt, Lich Bane, and Nashor's Tooth. Players who included these items in their builds had a higher win rate than those who tried for other Katarina builds. Similarly, if you are playing a varied enemy team comp, you should strongly consider getting yourself the Domination, and Precision runes. In recent games, she won the largest number of her rounds when equipped with these runes.
We established our Katarina build recommendations by examining 83,764 recently ranked League of Legends matches with her in them.

With so many games in our dataset, we are very confident in our recommended builds.
