Let me explain something. This is not a build for all games. This is a build i created trying to win ranked games in bronze and silver. THIS IS NOT A BUILD FOR HIGH ELO GAMES! this is just a build for the good players of yours who win mid lane and always lose because the F***N TOP feed... so, try this when you are the most fed champ of your team but all the enemy team focus on you. With this build katarina will be able to survive during all the teamfight, dealting tons of dmg to the enemy team, at the same time. well. the reason this build will never gonna work in high elo games is because if they buy magic resist, you are completelly F***ED UP. But in high elo games, you dont need to do it because there are not such scores as 0-4-0 in 8 minutes games from your top.

I actually i believe that katarina is a champ able to chase kills till her last breath. + if you know how to play katarina you know very well that you must find the perfect moment to enter a teamfight. so i believe that you need both of them (Flash + Ghost) if you want to reach her limits.

Yes it is. IT IS TROLL. But remember. You are playing with bronze. They believe you are the katarina they know, one of the most squishy champs riot has create. and they will use all spells on you but you will be still alive. You have good dmg around you (+sunfire), high HP, more than 100 armor, almost 100 magic resist, and tons of LifeSteal and SpellVamp.

Use W for farming till lvl 3. After lvl 3, try to farm without using E. try to keep it for a case of gank...or to avoid any enemy spell

Keep in mind : you are a kind of tank, you are not the one who will start the teamfight, but you are the one who will do lot of dmg so dont wait... when you see a teamfight. SHUNPO IN THERE.

You have to play many games... Play aggain and again and again and again because katarina is champion as good as the summoner. The fastest your reactions are, THE FASTER KATARINA YOUR KATARINA IS...

Try this build. This is an advices by someone with great experience in bronze and silver.
