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 complements his predatory spirit."

So Jungle Warwick is open to discussion with what he brings to the table, but these are the main facts, he allows all lanes to get pretty much 100% EXP from them since he isn't needed due to him jungling to start with. With this in mind he allows you to have map control/awareness due to jungling he will be grabbing Wards and with the build above you can switch out the Madred's Bloodrazor with a simple Wriggle's Lantern for the free ward, this allows early game control which can help your team massively in the long term. Also in mind, Jungle Warwick will be picking up the constant blue and red buffs making Top Lane and even Bottom Lane Ganks insanely easy with your ULT and your Team mates piling on the targeted enemy.Finally it allows you to help any ... ANY ... ANY!!!!! lane which seems to be struggling or weak since you are peacefully leveling up in your jungle you will stay on track with leveling, however your team mates may get an early death which will in turn result in a weaker lane, So Warwick can help clean any lane and put it back on track.

In case you want to play Lanewick, this allows another champion to be a jungler which can throw the enemy team. In general you want to have the solo lane, however this doesn't mean you have too, LaneWick is just as good or better in your opinion with a partner since the extra CC. In the best case a 1v1-Lane, this will let you realise your full potential due to the level advantage (you want to reach level 9 aka level 5 @ Hungering Strike as soon as possible) and your lane dominance possibilities will increase...meaning...you will kill...alot!

If there's no other jungler for your team, your lanepartner should have another stun or some CC to compensate your weakness when you use your ult.
Some great laningpartners: Amumu Alistar Ashe Evelynn Fiddlesticks Shen Udyr Veigar

Dont play Lanewick if your team has no initiator or at least enough CC. You CANT initiate a teamfight as Warwick, if jungling or not. If your team has no initiator and not that much CC, you wont be able to play any style of Warwick anyway...apart from one ;)

Lanewick is another funny way of playing this awesome champion. Don't get stuck with jungling, there are always alternatives!

A lot of people playing standard jungle-Warwick complain about his lategame-weakness. Well, they're right. Escpecially since the Bloodrazor-core offers you not really any survivability (what you really need since you are absolutely melee: your Hungering Strike is short-ranged, your Hunters Call buffs your melee-autoattacks, your Blood Scent is to get close to the enemy and even your R is to get to the enemy...), just some offense (which is also the same what your Hungering Strike offers and since a Bloodrazor-Warwick cant just run to the enemys and autoattack, spamming your Hungering Strike is more viable. But with this build Warwick is more like an offtank with a strong defense, smart damage, some support and the ability to shut down the enemys DD with the Infinite Duress

You never need to use Smite which is like ... BONUS! since you can switch with Ignite or Exhaust .

So what's difference so far ? well this is an over-looked build but when used effectively it will prove itself as a major build to be considered. MageWick allows you to build AP and not waste it on smaller bursts but allows giant survivability, due to the major fact of Hungering Strike this will deal around 300 - 700 damage (lets say) and then it will heal you at least 1/4 - 1/2 of your health which is so mad for Warwick players, this allows you to hit considerably high and chase with Blood Scent which shows you how great MageWick can be. One down fall compared to the other builds is your basic attacks don't deal a great amount but still has killing potential.

With this a whole new door opens up to you since your building AP like a boss you can play like an AP Nunu & Willump which in terms is insane since of the high hits you will make, item build can be swaped alot easier for the sitution since if you need HP grab an Rylai's Crystal Scepter if you need Magic Res grab Abyssal Mask the items are limitless and yet still can benefit you.

Eternal Thirst

Eternal Thirst - Each of Warwick's attacks will heal him for 6 / 12 / 18 health. Each successive attack against the same target will stack this amount of healing to Warwick up to a maximum of 3 stacks per strike. The stacks remain for 4 seconds.

This Allows you to have a built in Life Steal which means you dont need to focus on grabbing a large amount of Life Steal items, which benefits you in money, also it allows you to jungle alot more effectively and to kill the dragon with ease.

Hungering Strike

Hungering Strike - Takes a bite out of enemy unit for damage and heals Warwick.
Strikes an enemy for the greater value between 75/125/175/225/275 (+1 per ability power) and 8/11/14/17/20% of the target's maximum health (can only do flat damage to monsters), and heals Warwick for 100% of the damage dealt.

Cooldown - 10/9/8/7/6 seconds
Cost - 60/70/80/90/100 Mana
Range - 400

With all builds this is your main weapon it deals a mass amount of damage and heals you, depending on the build you choose determins the Damage and Health Regain.

Hunters Call
Hunters Call - Warwick lets out a howl, increasing all nearby friendly champions' attack speed for a short time.
Warwick lets out a howl that inspires all nearby allied champions. This increases Warwick's attack speed by 40/50/60/70/80% and all nearby friendly champions' attack speed by half of that for 10 seconds.

Cooldown - 30/27/24/21/18 seconds
Cost - 35/35/35/35/35 Mana
Range - Self + 1200 AoE

This doesn't change on any build apart from when it reach's level 5, this will grant you attack speed and while jungling this is a key skill to choose.

Blood Scent

Blood Scent - Warwick passively senses weakened enemy champions around him. The scent of blood sends him into a fury causing him to move at incredible speeds.
Warwick senses enemy champions under 50% life within 1500/2300/3100/3900/4700 distance of him; Upon sensing an enemy at low life he will gain 20/25/30/35/40% Movement Speed.

Cooldown - 4 seconds
Cost - Passive/Toggle
Range - 1500/2300/3100/3900/4700

This is useful mainly for the MageWick and Jungle Warwick since it allows you to chase your enemy down easier with the large buffs you will gain from it.


Infinite Duress

Infinite Duress - Warwick lunges at an enemy Champion, stunning them and dealing damage for a few seconds.
Warwick lunges at an enemy Champion, stunning them for 1.7 seconds. While they are stunned, Warwick quickly strikes the target 5 times for 33% of his attack damage plus 40/60/80. Warwick gains an additional 30% lifesteal while performing Infinite Duress.

Cooldown - 90/80/70 seconds
Cost - 100/125/150 Mana
Range - 700

This is your ULT and OH MY its so fun and usefull, in team fights when you have an initiator such as Ashe with her Enchanted Crystal Arrow you can jump instantly on them with this to either finish or to get them down to around 20% or below HP which is great since you can finish with your Hungering Strike. This ULT is the reason GANKING with Jungle Warwick works because it surpress's the enemy and deals a large proportion of damage and heals at the same time.

From here i just simply shown the three main builds i believe Warwick is great at, i didn't include TANK Warwick since i think its pointless since your there to kill not to take damage ... however if you guys like the builds and the differances comment and like the build and if you want more adding to it such as Jungle Routes, and so on...REQUEST IT!!! :) and ill gladly do it.
