First build lol..... Talon is a assassin burst clean up role type of champion and excels in team fights nuking down one target and or escaping.

Pros. Cons.
Hes heavy nuker Very squishy
Great late game Item dependent
Great in team fights If he gets caught by alot of cc your screwed
Great in assassin role Item dependent
Can be in any lane Risky 1v1 if ult is down
Dominates mostly any mid lane champ

I go for 9 Marks of desolation always good for any AD Dps

Also 9 Seals of Resilience great for armor early game and makes u not worry about most defense items

9 glyphs of Warding again great defense for mage or AP damnage dealers like if your top lane against a kennen or rumble

Now Quints are usally desolation but i go for that little bit of Attack to go mid lane and shut them down

I go for a 21-6-3 build getting everything but crit in offense and armor and magic resist in defense so it can add on with my runes the 3 in uttility is 10% less time being dead good on any champion

This has been a debate on Talon like it has on Trundle

His passive mercy is good with frozen mallet
But Trinity Force provides that with a smaller chane yet it has Sheen built in which is great for Noxian Dimplomacy

Flash and Exhaust are great on him
Flash is good for catching up running away

Exhaust is good when someone in running away having the enemy carry do nothing to you or your teammates or just to slow someone down

Ignite is good to if you want to secure a little bit of kills early to carry

Lastly is ghost if you need a little bit more escape mechanism from heavy cc enemys or just scary hunters like noctrune yi fortune just grab ghost

Just harrass with w and you will dominate most of the game

I know this isnt the best build but it is my first
