In this guide I will show how to play better with Talon - The Blade's Shadow.

Pros.

Good Damage all game.
Good Farmer.
Great Cooldown (lvl 18 Ultimate cooldown 24 seconds).
If you have a good enter on team fight you can kill easily and judge the TF.
Great Ganker.

Cons.

Learn enter in Team Fight.
Ranged Champs.
Low Mana until sheen.
Focused on TF.

Marks - 9x Grater Mark of Desolation
Seals - 9x Grater Seal of Resilience
Glyphs - 9x Grater Glyph of Celerity
Quintessences - 1x Grater Quintessence of Desolation
2x Grater Quintessence of Fortitude

With this runes you can get a good damage all game and great Cooldowns.

Marks - 9x Grater Mark of Desolation
Seals - 9x Grater Seal of Clarity
Glyphs - 9x Grater Glyph of Warding
Quintessences - 1x Grater Quintessence of Desolation
2x Grater Quintessence of Fortitude

Alternative more mana still do good damage too.

I adopted a 21/0/9 Masteries for doing good damage all game and kill more easily.

(if you take Second solo lane you should take 9/21/0 Masteries)

Flash - Good for offensive and defensive jobs.
Exhaust - Good to kill and gank or flee.
Ghost - Flee and make a perfect Ultimate.
Ignite (not necessary)

All other spells is for trolling

E > Q > W > R > Q

I prefer this Sequence you go silence the enemy, make damage, slows the enemy and you can do more easily a perfect Ultimate.(it's more effective on ranged champs)

W > E > Q > R > W > Q

Mercury's Treads - In Seals i have Armor and now Magic Resistance for survivability, and Tenacity if you get focused by enemies.

Youmuu's Ghostblade - This item represents all Talon is Damage, Critical Strikes, Cooldown Reduction, Armor Penetration and 5 gold every 10 seconds (helps you earn more gold). The Active ability helps you gank mid, bot or top (depends your lane) and your Melee mates in Team fights.

Trinity Force - Combo with Noxian Deplomacy doing a great damage also with your other skills, more movement & attack speed will help you with ganks and kill more easily.

The Bloodthirster - Damage and Lifesteal to help your hp. Collects kills and get more damage.

Infinity Edge - The ultimate AD item more damage.

6º item - Banshee's Veil, Bloodthirster, Frozen Mallet, Guardian Angel, Madred's Bloodrazor, Quicksilver Sash.

In early game you have collect max gold you can, and try kill anyone(You need farm).
Don't let they kill you.
Use the bushes and attack your opponents with the Noxian Diplomacy.
At lvl 6 combine with your mid mate and go gank mid.

IMPORTANT: Buy constantly 3/4/5 Red Potions and 1 ward.

Push lane if need, go gank enemies and jungle after you destroy your lane tower or your tower.
Help your mates with buffs.
Keep Collecting Gold.
Kill the Dragon/Baron.

Find a place you can hide 2 seconds after start the battle attack with the first skill sequence if you need use Flash. Your target is AP dps, Support and Carry, try make the sequence as fast as you can if your team destroy the other team keep attack if not leave the Team Fight.
One of the obstacles is Thornmail, don't attack a champ with thornmail talk to your mates how to distract and kill the champ with.
