This is my personal Hunter Skill :)

It's a build for max damage per attack speed , armor penetration Greater Mark of Desolation Greater Quintessence of Desolation and a little magic resist to live a bit longer to make more dmg :)

Start Item ->
Just to live and fight a bit longer on the lane at the beginning nd make a bit more dmg to rise youzr leve a bit faster.

First Recall -> or
The Greaves are good for more attack speed. In most cases Mercury's Treads are the better choice. It's a choice between dmg and protection.

Second Recall -> + +
With this items the attack speed and crit is moving up and that increase your dmg very fast. Becouse yor attack speed is know higher, Vampiric Scepter is a good choice if the game is running slow. If u are going to rush the enemies base in next time, u should skip it.

Third Recall -> +
Know it is time to increase the dmg a bit more. Phantom Dancer let you hunt your enemies down faster.
The same with Madred's Bloodrazor, but it gives you as the first item some protection what you will need at the enemie base rush.

Fourth Recall -> +
Know it's time for more protection. You will see, good enemies will focus you, becouse you are the hunter most damage thingi ;)
Guardian Angel will be a very good choice to stand up after death and hunt the enemies down. They will be surprised. Banshee's Veil givces you a good protection too, with more live, mana and magical resist. But more important is the spell block.
If you are going to win and you are not the main target, you can skip one thing.

End Items -> or or
Now you have 6 items and it is time to sell the start item Doran's Blade when you don't have done it until now. The choice of which item you will use depends on your own play and how the match is going.
If you need only more damage, The Black Cleaver is the best choice and I recommend it.
If you are doing a lot of kills without dying, than The Bloodthirster is the better choice. But the stacks are loosing if you die.
If you are the main target at group fights and you needa bit more protection and also god damage, Frozen Mallet will help you.


At the end my six items.

is an importent Spell to get to and away from your enemies.
is a good choice at low summoner level. It helps you a lot to die not so fast.

On higher level with more general life and/or protection (or when you can play better ^^) you shuld use instead of Heal for the same reasons as Flash.


Alternative
is a good choice to support the towers and the other champions.
can be a good support spell, but let a Heimerdinger or someone else use it.
