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

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 toward 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.

Warwick is the best jungler in League Of Legends, if you ask me. At lvl 6 you can kill the dragon in 3v3 with ease, you can do it at lvl 4 if you know what you are doing.

Combine this with your E when you chase someone and you are going to very fast. This spell is good for WW cause he's really not that fast without it.

Use this and your R and your target is going to lose HP quick.

It's simple you part in teamfights is to deal lots of damage over short time.

Pros:
- WW is very OP!
- With all the lifesteal and amor it's not easy to kill you
- Squishy enemies dont stand a chance
- He's dificult to kill

Cons:
- He can be hard to learn so if you are new to the game i do not recomend that you start with this char. (Trust me he was my first main and i SUCKED!)

This was a 3v3 match

Another 3v3 match
