This build guide for Warwick and is a jungle build/guide by ExenoM.
After level six, his ganks are sure kills, it's getting there that's usually the problem. One of the tankiest junglers in the game.

Warwick is a jungler/tank. He is a safe jungler that keeps his health relatively high when jungling compared to other junglers. Warwick is able to inflict a high amount of damage while staying alive in team fights making it easy for him to focus the other team’s carries and take them down, which can be game changing. Pick Warwick when your team needs a Jungle champion that is able to tank as well. Warwick is a little harder to play when other team has heavy CC “Crowd Control” which prevents him from life stealing or stop his ultimate.

Lore

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.

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

*Warwick is a very experience reliant jungler with high sustain. Jungle as long as you can to try to rush 6 as fast as possible. Starting on Wraiths secures them so enemy junglers cannot steal them as you are a slower jungler. Always ask your teammates to not take your minigolems as it will delay your level 6 significantly. They can take your wolves instead, if they please.
