Talon is a assasin. He is really well in killing squishy targets and jump in and out fights. His spells give him good crowdcontrol and he is a good chaser.
Talon can farm really well and can dominate the game.

I play Talon on the solo top. I try to farm as many minnions as possible. I try not to waste my mana 'cos Talon only has about 500 mana in early game. When i do farm with my spells i use Rake. But if I do so I always try to kill atleast 2 or 3 minnions and hit the enemy to. With the first gank i try everything to get the kill for having a good early game. In the late game I try not to die in the teamfights. If Talon gets stunned he will die instantly, so care. Jump first on the AD-Carry and the sqishy targets to kill they're damagedealer.

Passive: Talon deals more damage against targets with disables( silence, slow, stun, snare )
Q( Noxian Diplomacy ): Talon next basic attack deals bonus damage and marks the target. The target gets visible and looses health over a short time. The speel resets the attacktimer
W( Rake ): Talon sends out three blades in a cone and then they fly back to Talon. Every blade deals damage and slows enemys that are hit.
R( Shadow Assault ): Talon sends out blades around him that damgaes all hit enemys. Then he grants invisibility and bonus movement speed. After a short delay or when Talon hits an enemys the blades fly back to Talon and deal again damage.

Skill combo: E-basic attack-Q-W-R-Ignite

Pros: - Talon bursts the enemys down really fast
- instantkill on squishy targets
- good chaser ( assasin )

cons: - really squishy ( that why frozen and early giant belt )
- mana intensive
- when focused instant down

Marks: I use armour penetration marks for dealing more damage
Seals: I use mana reg seals per level 'cos he needs at al times mana
Glyphs: I use mana reg glyphs again for more mana and cdr glyphs for casting at all time
Quints: I use again armour penetration quints for more damage

I focus on having as much damage with 20 points in offense and 9 points in utility for more mana reg and a bit more speed.

I max Rake right away at level 9. Noxian Diplomacy is maxed at level 13 and cutthroat at level 18. At level 6,11,16 I give one point in Shadow Assault.

Summoner Spells

Flash
Highly recommended
Gets you in good position or gets you out of tough situations. Definitely a good summoner spell, especially when you flash over a wall and deny enemies a kill muhahaha. Highly recommended.


Ignite
Highly Recommended
good for getting kills you might otherwise won't. General usage in a standard game is pretty often so this is immensely useful. If playing draft pick try to predict who you will be laning with. Generally its quite easy to tell.


Cleanse
Highly recommended; situational
If you don't like getting mercury's treads or find that the enemy team is stacking CC, this is the spell to get. It literally is a free quicksilver sash, so its great.


Exhaust
Recommended
The ultimate chasing spell but sacrificing survivability. Also makes use of your passive. Not bad


Ghost
Decent - aimed at survivability
The opposite of exhaust. Good for escaping, but offensively its not as great as exhaust. Recommended.


Teleport
If you have a Teemo/someone who wards
This is great if you have a good Teemo or a ward *****. Nonetheless, using this defensively is not great, but if in the event that you can use this offensively, its great

normal build:

-Boots: good speed for the beginning and let you get 3 health pots for better early on the solo lane
-The Brutalizer: good amount of damage, amour pen and cdr
-B.F. Sword: nice damage again. Start getting a nuker
-Boots:- Cdr Boots: normal speed + cdr
- 3 Boots: really fast
- Mdef: normal speed + mdef + lesser cc
- 5 Boots: best chaser + roomer + get into position
-Giant's Belt: bonus health. let you play more agressive
-Zeal: ats + crit + speed
-B.F Sword/Infinty Edge: more damage and heavy crits
-Phantom Dancer: more ats + crit + movement ( Pahantom Dancer + Infinty Edge = hard and often crits )
-Frozen Mallet: slow + damage + enough hp for dying instantly
-Youmuu's Ghostblade: dmg + crit + amazing active

Alternative Items :
-Guardian Angel: not dying often 'cos resists and passive
-Banshee's Vail/Quicksilver Sash: mdef + dont getting any cc ( Malzahar ult me but I ate some oranges and it was k! ^^)
-Hexdrinker: you cant getting nuked *trollface*

Talon is really well in killing squishys and he can chase good. He deals tons of damage, but he is still squishy. He is totaly viable in ranked games and is a nightmare in every game.
