Hey whats up, This is my caitlynn build that i made. It took me a long time to get used to her and start doing well, i was getting frustrated at first and was like why did i buy this champ? But i persaveered and tried diffrent kinds of builds and i really wanted one with some mana regen and i picked an item that many people dont use and i think they just glaze right over it like its nothing. So then my build improved and it started shaping up.
This is one of my builds that im actually going the whole 9 yards and writing a indepth guide. (or at least for me :p) So please feel free to critize and tell me where i can improve, but please dont just vote this down and not comment. I know i do need help in my runes cause i am not that great so if any1 could help me thatd be great. Thanks and Enjoy

-Pros

Great Damage dealer with her passive
Can Shut down runners with Ult and using net backwards to chase
Great Top and Bottom laner because of bush's
Great harraser
Can be detemining factor in team fights
list]
-Cons
Squishy
If targeted by team can be taken out of the fight
Mana pool

Yes the big thing that determines how good a build truly is. Now i went to get the mana regen item leading up to tiamat which i find very useful for 3 main reasons. One because the damage alone, Second because of the mana regen which is great for Caitlynn because of her lack of mana, Third for the nice splash damagae. Now you maybe saying that as a main reason? well it can make or break a team fight because if you hit with so high and usually their all around in a clump so the damage is nicely distributed. Now next is berserker greaves no big reason their just for the Attack speed that aids you. next is Frost mallet, i picked this for to go before black cleaver because of the Health, 4th is Black cleaver which is for the attack speed and damage. 5th is Infity edge,Last madreds, i am still debating wether to get phantom's or this the passive is nice on madred but phantom gets more crits and speed, Anyway it is not abig matter cause you wont get to this point usually in a game. Those are my item choices by all means give any ideas.

So as i exlaine in my introduction that i am bad with runes and i really need help, anyway i went with damage so as to be more beefed up at the start inbetween getting your boots and the cleavaaaaa, next i went attack speed to add a little more cause you prob will be sitting at around 1.2 to 1.3 As before you get your late game Attack speed item, Next was mana regen which i only picked one item that had mana regen, its not really a major necesity but i like to do alot of spells with her specially her Piltover spell. Last was health because she is in dire need of health till you get frozen mallet even then she is kinda squishy. So their you go my rune choices :)

For masteries i went with a common 21-0-9 I went to get max damage but also to get some mana regen as to help out, again this is my own use and you can pick what ever you want to go along with my build. But feel free to post and tell me if you find a better mastery set then mind, i will try it and and if its better alter the one i have on atm

You should not initiate team fights unless you know you can come out alive. Now in team fights you should stick back and attack from afar hitting really hard, Once again if you see your team starting to lose you should use piltover then net on the main attacking and chasing your team, but if you are winning you should use ult on the first runner then net backwards to try and follow the chasers
Laning is a big thing, you usually want to get somekind of stunner/holder/disabler, good laners are, Morg for her nice little hold, Lux for the same reason, Malzahar just because of his ult so kinda, Rammus for stun and taunt, Ashe for her slow and her ult, although she could possibly be mid soloing, Blitz crank for his pull and knock up. Theirs more but i cant think of them.

Ah yes not a big chapter in my guide to caitlynn but one to talk about, i go for the piltover ability to max out first by getting the net 2nd and the trap 4th, after that igo for net to max out last of course the traps. Im not to big on the traps but they have gotten me a few kills so by all means you can max those before nets, but the key to this build is the piltover ability.

Ah yes the big Summoner spells question, i went with flash and exhaust exhaust to slow and get the kills, while flash combined with ur net can escape and also catch runners in no time, You can also defer to ghost which is usefel. But those are my summoner spells :)

All in all i kind of made this build on a whim and it worked for me with successful results, all though i have not tried it in ranked play because i am not high enough level to play in ranked play, (Only level 26 :( ) This build was made in about 30-40 minutes and as i said my really fuild build and i hope you guys find success with this one. Thanks and i ask again Please comment and rate ^_^.
