Warwick counted himself amongst the most powerful and revered men in his home city-state of Zaun. Over the course of his infamous career as an alchemist, Warwick won many honors for his craft, not the least of which was a lucrative offer for service in the Noxian military during their campaigns against Ionia. Sequestered in his labs far from the front lines, Warwick and his apprentice Singed toiled relentlessly to manufacture all manner of appalling concoctions for the Noxian army. So potent was his art that even the greatest of Ionia's healers - under the leadership of the Starchild Soraka - struggled to combat the poisons and chemical weapons generated by his despicable mind. Warwick's reign of terror grew so horrific that his very name became a curse in the eyes of his Ionian foes, and they began referring to him only as ''the Deathmaker.''

But even one under the protection of the Noxian High Command is not wholly beyond the reach of retribution. For as Soraka strode across the myriad of death and destruction left in the wake of one of Warwick's chemical attacks, her heart finally gave way. She called down the wrath of the cosmos on Warwick, wishing that his form should mirror the cruelty in his heart - a curse that would come at the price of her aspiring divinity. Within his laboratory, a terrible thirst took hold over Warwick. As his apprentice looked on in horror, Warwick threw open the doors to his bastion and sprinted off towards parts unknown, a bloodcurdling howling marking his passage. He had become a werewolf; a wild, murderous beast. Today, the Blood Hunter fights for Noxus within the League of Legends... thankful of the curse that his now-mortal enemy bestowed upon him.

''The rage of the beast now compliments his predatory spirit.'' -- Singed, the Mad Chemist, upon witnessing his master's transformation

Hello all.
My name is Joachim, i come from Denmark. And i just one week i have been trying different builds to Warwick. But finally i made the perfect build that gave me a 22/1/9 score. My attack speed was pretty high so was my run speed and attack damage. There is no one who can run away from you when your BLOOD SCENT activates, and i seriously love that.
And because of your BLOODTHIRSTER and PHANTHOM DANCER its very difficult to take you down 1v1. Your lifesteal is insane and your attacks speed is pretty high too.

The first item is Berserker´s Greaves, only to increase you movement speed and attack speed.
Next its good to buy a frozen mallet so that your target gets slowed. After that i buy a Phantom Dancer, to increase my attack speed, critical strike and movement speed. Then i buy a Black Cleaver to increase my attack damage and attack speed. Then comes Bloodthirster so that i can get more attack damage and life steal over time. And the last item is Infinity Edge so that my attack damage get higher together with my critical chance.
Remember this works best when you have them all i lvl 18.
ENJOY!
