Not Updated For Current Season
I made this build just to specify the item you should get for Caitlyn and getting some feed back. First of all You would start out with a Doran's Blade and a Health pot. I personal don't really take mid and let a Stronger Castor to take mid, but it is an option. Do not solo a lane if you have a jungler on you team, Caitlyn does not do well 1 v 2.
Once you head back you should have enough money to buy bersker and stock up on some health pots.By mid game you should have now finsihed 2 zeals and now working on you b.f. and placed 2 or 3 wards down. Elixer of Fortituede and Agility for the extra hp and atck speed. You should have gotten at least 2 kills by now if you are doing this correctly stay in the bush while laning and just harass with you 8th shot.
once you have your b.f. sword and your two elixers up you turn that B.F. to an infinity edge for your main noob slaughtering machine. Quickly turn your 2 zeal's into phantom dancers so you have insain movement speed and a garanteed crit. The atck speed will aid in the noob slaughtering feast as well.
Now all you have to worry about is the tanks... quickly grab your last whispers and move onto your bloodthrister, but if your getting many kills then just build a bloodthirsters and worry about the tanks later, because after all they are tanks their not suppose to die...
Alright now its time to finnaly kill those tanks that you couldn't kill as easily as a meele dps,because they have those snazy randium's, force of natures, psp, gamboys, t.v., anyways you can't kill them... If the tanks are truly bothering you or if they have more than 2 or 3 people on the team that has 100 or more armor grab last whispers if not grab Black Cleaver.
Once you finish all your items you can easily snip all the squishy carry's down and score a pentakill while you finish off the tanks.
REMEMBER NEVER START A FIGHT LET YOUR TANKS DO THAT! Count to 3 then go into the fight behind the enemies team, or just hide behind some wall and just press your q if you guys are just waiting for the chance to start one.
That sums up probably all I need to talk about Caitlyn does have some mana issues, but if you are smart then grab the freaken dang blue buff or ask nicely to the jungler.
Please I apologize for my many grammer mistakes and spelling errors. I wanted to just show everyone this build, but if you are goign to copy my item build then please give me some credit.
