This build Ins't a build for every game as Talon. If you find yourself playing against squishy carrys and you would like to see them melt in front of you through out the game. This guide for you (i have yet to try this in ranked)

THIS IS MY FIRST GUIDE =)

Pros

VERY HEAVY NUKE
great escape
low ult cooldown
good mid against squishes

Cons

easily focused down
no real escape until level 6
has a lot of issue laning against tanks

Armor Pin marks- is great through out the game helps you do true damage on creeps, all your abilitya are easily countered by armor this helps a little
armor seals- help for survivability early game
mag res glyphs- again to help with survivability early game

like a said before this build is not for every game its for those ones where your going against squishes
first you start withand x3

then when you get 800g in your lane go back and grab a this will help you regen mana and hp helping you to lane for a long time plus the 5GP10 helps you get your items late game i hold onto this item untill late game

the next time you go back if you can grab your thats great but if you dont just start buying the x2

now heers where the good stuf starts to a
sell your pick up a for the damage + armor pin

upgrade your boots
at this point you should be nuking everyone in the game for over 75% hp with 1 burst

Now you just finish up the build with 2 more
and make sure to farm them!
