You probably have so little votes because you require a comment with it. Some people just don't want to comment or don't know what to say i.e. me. But this guide has been very helpful as I am just starting to use Talon and I am looking for different ways to play him. Thank you for taking the time to make this

scratch that, i now take:

Doran's Blade
Ionian Boots of Lucidity
brutaliser
Maw of Malmortius
Bloodthirster
Last Whisper
Banshee's Veil
Bloodthirster

yeah its ok overall, personally i take heal over ignite and take the 9 defensive points in accordance with the improved heal.

i start with Doran's Blade for the health and AD rather than the lifesteal. then merc treads (as you have) and brutaliser for the cheap AD and armor pen at an early level.

Hexdrinker and Maw of Malmortius next for even more cheap AD (the Long Sword's) and the great passive, perfect for talon when enemy teams try to burst you down.

Last Whisper is another core item for talon and i take it as my 3rd item for the incredible armor pen it provides, in synergy with brutaliser most armor is gone :)

Sheen is perfect also for talon as when combined with your Q with the items listed above, the damage is excellent and is basically another burst ability. the thing to note here is to not go all the way to Trinity Force as Zeal and Phage aren't going to help your burst. rather Bloodthirster is better for the AD and is better at this stage of the game as your AD is just about as high as you will get (for the lifesteal).

Guardian Angel makes you that much harder to burst out of a teamfight in combination with Maw of Malmortius and is still preferable to finishing Trinity Force. finally finish of Trinity Force and you have an incredibly bursty, hard to take down assassin.

Thanks for reminding me to upgrade Brutalizer, I had forgotten to put that in.
As for life steal,
It isn't a main theme in the build. The only lifesteal item is Bloodthirster, and I just had a couple of lifesteal masteries.
Also, with all of the AD Talon has, the lifesteal will still give you a significant amount of health on every attack. Furthermore, even with low attack speed, his Q gives him a double attack every three seconds, which more than makes up for it.
As for the other team not letting you autoattack their carries, the lifesteal still counts with only a couple of attacks. More importantly, the lifesteal in this build is for sustain in lane and out of fights as well.

Thanks for reading!

you have brutaliser but don't turn it to yommumu's? also if your going lifesteal u need attack speed and talon can't be built as an AS champion as the enemy team are not going to let you stand around auto attacking their carries
