Laning

Talon is a great champion, however many believe he is difficult to play or do not play him properly.
As Talon ur early game job is to harass in lane with Rake. The constant rake harass will drop down you opponent untill your jungler is able to come top lane for a killer gank or two.
I start with boots and three health potions for more mobility in case of ganks, and for the sustain with the potions.
After getting a phage(for my 10% passive damage) and boots, I begin to gank, after pushing your opponent out of lane its simple to gank mid, after tellig mid to let the enemy push, for a quick kill because of the massive amount of ad burst and ap burst.

Talon with this build is a great ganker, at level 6 he has his ulti, which allows him to cloak to iniate a fight.

Begin with your ulti and run to the opposite side of your opponent, quickly shoot rake.
This should deal a great amount of damage.
Follow quickly with your Noxian Diplomacy.
At this point they should be running, but theyre not getting away, jump to them with E and smack em a few.
If theyre not dead by this point, they need to B back. Remember to always push a clear lane quickly.
Build up your items whenever possible, however take every advantage possable to push out lanes when clear, your noxian diplomacy (q) will work on turrets (- the dot), and using it frequently will help drop turrets quickly.

Talon late game as the build, is the most scary sob u will ever see/not see ever. Forget a Nasus with 3000000 stacks on his Q if u cant pull it off theres no point. I use the infinity edge for the crit and large attack damage.
I use the bloodthirster for the lifesteal, and the +100 attack damage stacks, making him godlike.
The Trinity force often confuses people. I use it for the attack/movement speed on the zeal, the slow and life from the Phage, and the 10% damage from passive when slowed. Finally I use it for the sheen passive woth double damage after a skill, and since Talon is a great combo and auto attacker, they drop quickly, as well as it works along with his noxian diplomacy. Giving him even more damage burst with his combo.
The Ghostblade is a great item. Its used for the armour pen. along with the active. Using the ghostblade before your combo greatly increases the damage.

The last whisper is quite obvious. Damage+penetration. If the enemies built no armour, simply swap it out for a warmogs, or if your Godlike, a sword of the occult. Never too late if you can pick off an emeny within a second if they stray from the pack.
