Thats my build for Talon, The Blade's Shadow.
Talon is a very strong AD Caster, his full combo can take down almost any squishy champion in no time.
This guide focus Atack Damage and CDR, as Talon's auto attack isn't that good.

PS: I haven't lost a match with Talon using that build until now.
(27/08/2011).

For runes i take:

Marks: Armor Penetration
Glyphs: flat Armor
Seals: flat Magic Resist
Quintessences: Armor penetration

That provides me enough armor penetration for my skills to deal alot of damage, and the armor and magic resist needed to stay in lane early game, since Talon is very fragile and has no espape mechanism before he gets his ult.

For masteries i take 21/0/9, focusing and CDR.

For itens i start with a and I try to stay in lane long enough to buy , the damage and CDR is very usefull early game, and if possible a .
Next time i go back to base i close .
After that go for a , the slow is very good to your passive and you will need that extra health.
Now it's time to really get the high damage, get a The Bloodthister, if you are doing well start with the , if not start building if from Vampiric.
Now it's time to finish your [icon=Frozen Mallet, if you are fed you can buy a before finishing the Frozen.
Your last important item is Ininity Edgeafter you get it you should deal a huge amount of damage with your combo.
Last item should be a , for the survability as you should get focused alot.(if you are not doing very well, build this befone )

I only finish building if there's money left, it isn't that good on Talon, the good part of it is the low price Damage and CDR from at early game.

Situational Item

As for any champion situational itens may be required.
Against heavy AD team or a fed AD carry, build a after you finish

Basically all you need to do is harras your enemy with non-stop, you can almost spam it non-stop as mana isn't a concern on Talon.
Once you see that's your oponent cant deal a nice ammount of damage on you at a short time, jump on him using Cutthroat, activate and use , now it's time to decide, get back or chase. Talon has no escape mechanism so you should be very carefull when deciding wheter to jump on an enemy or not.

: There's not a right time to activate your Ultimate, you can initiate with it, or jump then activate it. I actually prefer to Cutthroat, , and then use , because if the enemy tries to run away you can chase him with the Movemente Speed Bonus.

For Spells is a MUST. As you have no escape mechanism, you WILL NEED it.

can be substituted if you want, i prefer it because helps alot while chasing and grants you a successful win on a 1vs1 against AD carrys.

Talon has a great burst, but is very squishy, if you know when to engage you can kill almost any champion in no time, but if you dont, you will get owned.


Tip

Try to always lane with someone who has CC, as your passive makes you deal more Damage to an enemy who's under CC.

Pros

-Huge damage in a small gap of time.
-Great farmer.
- 's stealth is very usefull when escaping.
-Quite easy to play.

Cons

-Extremely Squishy without Health items.
-Gets focused alot.
-Can't escape a fight without or Fash.

Talon is very flexible on a team, he's a great ganker, you can jump on anyone using Cutthroat silencing him at the same time, use to slow them, and to chase.
You can even initiate fights with , but it is not recomended as if you engage after a fight has already started, you can make the best use out of your Ultimate.

Farming with Talon is very easy, all you need to do is spam , i recommend hiting once each minion and then use , you should kill the whole wave by doing this.
For hitting all the minions stay next to the middle melle one in front of him and use towards the caster ones.

Here are my scores with Talon so far...
