alternative item:black cleaver, phantom dancer, madreds bloodrazor or last whisper
alternative item that isnt taken already
3:rd alterbative item that isnt taken or alternative defense item

Great guide, don't listen to the idiots who think that their small amount of experience beats large amounts combined with math to back it up.

Like I've said before, number crunching is truly a major pain to me and I'm no longer doing such a thing anymore in my replies. If you really think that Bloodthirster significantly beats Black Cleaver overall after building an Infinity Edge AND a Phantom Dancer, get it then.

Honestly, I've made my point in both my guide and my replies and STILL people refuse to read the reasons why I pick such items and why they're viable and provide the consistency and damage you need going from early to late game. It truly boggles my mind why people choose to have a weak early to mid game and then have a powerful late game in the end when you can be successful in all phases of the game.

Must say that I agree with leagues df, I have been testing different builds and build orders, and I will tell you where you error is:

Early mid game most of the damage you will deal will come from Q and R and the early construction of IE and BT will give you a huge damage increase to both.

Starks will aid in the form of arp but not in damage.

You may say as is better than skill casting, but I have found that early rush of this items and then construction of as is gamebreaking.

I believe that in lane poking is better than attacking constantly. This is the reason why AS is to me the last thing you should build.

Rushing this items can lead to riculous results such as 2 hitting a leblanc. I qd her from brush, saw her remaining hp and decided i would r. She died.

Afterwards I build PD and if the game continues I decide between Black Cleaver, LW and Starks. Black cleaver is better vs low armor targets. LW is better vs high armor. Starks is good in a AD heavy team.

All in all the only thing I may add is SotD is usefull vs jax and ninja tabi users. It provides a good ARP and AS as well and making you undodgeable.

I must also say that ad runes are not optimal, ARP are 80% better. The only good thing about ad runes is the probability that you will secure a higher cs, but overall it becomes useless as you increase yor ad.

I really like how you explained the playing style. I don't have anything to complain about with this build. Good job dude.

Misuse of words and poor sentence structure will result to a belief of insults.

Also, I find Black Cleaver serving a stronger purpose than Last Whisper. If they were put together, then that's fine. As one item on its own however, Black Cleaver is superior in quite a few ways. All of this number crunching is starting to make the headache worse, so I'm just going to make this math quick. Black Cleaver gives 55+ Base Damage, 15 x 3 Armor Pen (A total of 45) and a significant amount of Attack Speed increase. That allows more damage input with Phantom Dancer / Zeal and Berserker Greaves when you build this vs. Last Whisper that only has 40% Armor Penetration and 40+ Damage. The percentage only works well with people that have a very large amount of armor. Mostly the tank will have this significant amount of armor. However, lets take Caitlyn for example with Last Whisper.

At the time that you would build Last Whisper or Black Cleaver would average around Lv. 10 - 11+, at least that's the case for me. Her starting base armor is 13 + 3.5 per Level. So lets take that up to that level range and do the calculations of Last Whisper there.

13 + (3.5 x 11) = ????
13 + (38.5) = 51.3 - (51.3 x 0.40) = ???? <--- Calculations with Last Whisper
51.3 - 20.52 = 31.1 Armor Penetration.

That's 14.9 away from being equivalent from Black Cleaver's Armor Pen, -15 damage, and -30% Attack Speed. Now lets do the FULL calculations with the entire build.

I'm assuming you want Berserker's Greaves Infinity Edge Phantom Dancer Last Whisper then Bloodthirster? So I'll do consistency from start to finish in a match with that + the 15 Armor Pen that you start out with minus the Armor Pen quintessences.

Again, lets start at Lv. 11 - 15 with the calculations we have now.

Your build @ Lv. 11:

31 APen (Last Whisper) + 15 APen (Runes) = 46 total APen.
It stops there and raises bit by bit as players increase in level and if anyone buys armor, so it fluctuates.

15 x 3 Apen (Black Cleaver) + 25 APen (Runes) = 45 + 25 = 70 total APen.
Mine stops at 90 after Starks. 90 APen = Above AP Champ / AD Carry Champ Base Armor @ Lv. 18 if they don't buy armor, this means they have a base armor below 0 if you attack them which results true damage + bonus damage because the APen is exceeding the person's total Armor.

Then lets talk about consistency as you build Caitlyn :

I'll skip up to Infinity Egde and Zeal, because that's where the build changes anyways. Remember that I talked about consistency with Caitlyn. There's two ways you can go from this point on that will definitely become faulty as you progress to your final item. Here it is :

If you choose to build Phantom Dancer first, you lose consistent damage for the sake of trying to build up for more Attack Speed and Critical Chance.

If you choose Last Whisper, you drop down considerably again in consistency, because you're now lacking in attack speed at this point for the sake of 40% armor pen and some raw damage that isn't helping you at this level range because this item does not work till later or if EVERYONE buys a large amount of armor.

Remember that I said consistency works best with Caitlyn, if you can balance the armor pen, damage, attack speed and critical chance, AS YOU BUILD UP AND FINALIZE THE LAST ITEM then you'll do great in the end. That all leads up to Starks.

Gonna stop here on the reply, getting too long again for my brain to handle.

Wow, no need to get so angry. Im defently not trying to say that u suck or something, im just giving constructive critisisem. U should learm how to take it better... I'm commenting because I want to help that's all. Ofc u can not listen to me and keep the build as it is, but im just saying my opinion, in order to open your eyes for some stuff that at least I, find not to be the best way to go. I'm not just going around builds and trying to say that every1 are stupid or somehting...

Now, ill just make my self clear. I dont mean that u should not get Stark's and Arp Quints and stay with 60 Arp. What i'm saying, is that I think, AND ITS ONLY MY OPINION DONT GET MAD, is that u should also swich The Black Cleaver with LAst whisper. Since u wont have A lot of Flat Arp, LW will be very effective, especially against tanks/offtanks.

Just trying to help m8, no need to get angry.

I'm more or less insulted that you're saying that I don't know what I'm doing in the end. Honestly, if you don't agree with the build, don't comment in my guide the way you are now. I think I've played enough Caitlyn games in full premades to know what I'm doing.

You truly underestimate what Zeke's Harbinger can do ultimately in the end and it seems like you're not doing the number crunching here on your own. You also didn't read my explanation of Zeke's Harbinger did you?

Berserker's Greaves, Phantom Dancer, Black Cleaver, and Zeke's Harbinger.
They all have 1 thing in common, and that is Attack Speed. What synergizes with faster attack speed?

Damage Output. The faster you hit, the more damage you can put in giving you more even more chances to do critical damage per second. Zeke's Harbinger helps you obtain that extra 2 1/2 - 3rd hit per second.

Life Steal. 15% + 10% Life Steal and 60 + 40 Physical Damage from Bloodthirster. No Armor Penetration, No Attack Speed, ultimately meaning slower, less life leech and damage output. Do the calculations of Armor Penetration and Attack Speed.

Now lets talk about your silliness of replacing 10 Armor Pen, from a total of 25, with silly Attack Damage runes + The Bloodthirster. You might think that it helps early game for whatever purpose, but you forget that ALL Champions start with a bit of Armor, this means reduced damage. Not only that, you're not doing the total math of Armor Penetration that's being added here.

Armor Penetration Math:

25 (Runes) + 15 x 3 (Black Cleaver) + 20 (Starks) = 90 Armor Penetration if Black Cleaver stacks all 3, which it will.

Don't forget that some don't even have over 81 starting armor. Going over the person's total armor with Armor Penetration means EXTRA BONUS DAMAGE. That's assuming that the player doesn't buy armor.

You want me to drop it to 80 minus 20 (without Starks) for the sake of 6.75+ Extra Damage and 5% more Lifesteal and 100+ Damage that can be reduced greatly? That's silly talk when I can ultimately have 90 APen, Incredible Attack Speed, Nice amount of damage still thanks to APen and Attack Speed, and faster lifesteal. Never underestimate armor penetration and attack speed.

There's more deeper calculations of the build I'm using, but I'm not gonna cover that in my response because that's just too much explaining for my brain to handle to put into words.

I've argued enough about masteries and summoner spells, let alone the fact that this reply is long enough as it is. So I'm stopping it here.

OK, Ill answer ur answer, because again i dont really agree:

Starks's gives 40% attack speed, which is pretty high, 20 Arp and life steal which is low, and 20 HP/5 which is usless late game. All around, its not a good DPS item, mainly for the fact that it provides no AD at all, while Bloodthirster gives 60-100... This item is maily bught for its aura effect, and again, should be bought by some1 else on your team.

About exhaust. U say that in a well built team u will already have enough exhausts. Not true.
The meta eight now is that Carries takes exhaust, and a lot of it is because, no1 else will take it!
jungler-Smite
Solo top offtank- usually ignite to get an edge in the lane, and have more damage later on.
Mid Mage- Ignite, to add to the casters burst damage.
Support- CV
As i was saying, no1 is going to take Exhaust other than u! Maybe solo top. Anyway, Exhaust is great on carries, and most of the times the carry is the only one that will take it, and u want exhaust on your team...

"Why not take Perseverence? Save yourself the trouble of lacking mana to fire Ace in the Hole. If you're the type to die more often than you should, then by all means take Good Hands."
Save troubles? At lvl 18, Perseverence gives you 0.8 mana per 5 sec. Oh well OK thats it I saved the trouble its so awesome this even not 1 mana point. And thats at lvl 18, earlier, you will have somethin like 0.5 mana per 5. Lame. I would much prfer to have 6 less seconds to death time at late game. Those seconds can be game breaking, for example when u are dead, enemy tem starts baron, and your team are waiting for you so u can jump on them, ace them and take baron, or if u wont be in time, the enemy team will have baron, push and win.

AD Quints are awesome. Few people understand their ability to dominate early mid game. :(

I hope I made things more clear.

Some Updates:

Fixed a typo error on the explanation of 90 Caliber Net.
Added a section discussing about proper use of the Headshot Passive during laning phase.
Added further explanation of the use of Zeke's Harbinger in the Item Building section.
