This is a guide that shows how you can play warwick.
I play Warwick this way so it has been tested.
One footnote at the first. You will need a chapion in your team that can solo a lane 2 vs 1.
So far best champs for this are Annie or Tristana. Others will be able to do this too. But it will be risky. Even though most of the time it is not this lane in the game that fails.

The Real Guide

Summoner Spells

I think smite is very usefull in the jungle but if you do as in the guide it is not a requirement.

Flash is very usefull for escaping or ganking.
Ghost can be even more usefull since it greatly increases movementspeed for some time.

What I use myself:

Smite: it just makes you jungle a lot faster and with the masterie some gold every now and then.
Flash or Ghost: depends how i am feeling at the time. Both very usefull in ganking or escaping ganks

Masteries

Offensive (21)

Deadliness 3/3
Plentfull bouny 1/1
Alacrity 4/4
Sunder 3/3
Offensive Masterie 2/2
Brute Force 3/3
Lethaly 3/3
Sorcery (1/4)
Havoc 1/1 (optional Havoc 0/1)

Defensive (0)

Utility (9)

Good Hands 1/3
Perserverence 3/3
Awareness 4/4
Utility Mastery 1/2 (optional 2/2)

I use Havoc myself but Utility Mastery 2/2 can be very usefull too.
Since you get a lot off buffs over the time.

Another Good build is:
(21/9/0)

Offensive (21)

Deadliness 3/3
Plentfull bouny 1/1
Alacrity 4/4
Sunder 3/3
Offensive Masterie 2/2
Brute Force 3/3
Lethaly 3/3
Sorcery (1/4)
Havoc 1/1 (optional Havoc 0/1)

Defensive masteries:

Resistance (1/3)
Hardiness(3/3)
Evasion(4/4)
Nimbleness(1/1)

This build makes the starting with jungling a bit harder but is better in late game.

Runebook

This is what I use:

Marks : attack speed (red)
Seals : dodge (yellow)
Glyphs : mana regen (blue)
Quintesses : attack speed (purple)

These are quite usefull but i dont know if attack speed is what you realy need.
Crit chance would be nice to.
I am also sure that crit damage is quite fun.

Abilities

if you want to know what the skills do try warwick in a practise game ...
My build on this is :

1) Hungering Strike
2) Hunters Mark
3) Hungering Strike
4) Blood scent
5) Hungering Strike
6) Infinite Duress
7) Hungering Strike
8) Hunters Mark
9) Hungering Strike
10) Hunters Mark
11) Infinite Duress
12) Hunters Mark
13) Hunters Mark
14) Blood Scent
15) Blood Scent
16) Infinite Duress
17) Blood Scent
18) Blood Scent

Why do i max Hungering Strike?

It gives you a lot of extra damage and also heals you for the same amount.
It is great for finishing champions and has more range then your basic attack.
And since I dont go for lifesteal very soon it replaces it a bit.

Hunters Mark > Blood Scent?

Bloodscent doesnt realy help you in the jungle. And the extra attack speed gives you more lifesteal (passive ww)

Blood Scent at lvl 4?
It gives you an advantage in ganking low health champions. Not only it gives you more movementspeed but you can see the low-health champion when its not too far away too !
so its worth the 1 skill at lvl 4.

Item Build

1. Cloth Armor
2. Cloth Armor => Madred's Razors

The bonus dmg from this item is almost just as usefull as smite !

3. Boots of Mobility

Gives realy much movement speed and makes you travel easy. I prefer this boots over any others because it realy saves some time.

4. Madred's Razor => Madred's Bloodrazor

Realy Great item that helps you kill champions with much health easier

5.a Black Cleaver

Greatly boosts Ulti

5.b Frozen Mallet

Doesnt realy help you that much but a great item if the other team focusses you a lot + you dont need the lizard buff anymore

After this a bloodthirster might be a good idea. and try some other things if the game still goes on.


How to play
Well in the start go to the big fat Golem. Wait in the bushes and dont attack untill you are realy sure you wont be ganked. Once they see your Summoner Spells they will figure you are a jungler even before the game starts.

Go in the fight like this:
Smite on Golem.
Normal attack golem
When you lost a little hp use hungering strike.
From this part only hungering strike and basic attack.
Kill the 2 little lizards too.

go kill the 2 golems below (or up if you are purple team)
then go for the group of banshees.

Next is the lizard buff but kill the little lizards first.

now kill the last group of jungle creeps on your side.

Recall and finish you Madred's Razor.

Go for either a kill ( if there are some champs with low health)
or go finish the dragon ( you are strong enough and this realy helps your team).
If you go for the dragon: this is the time to use your Rally-spell. You might not need it but it sure helps you kill him faster.

After go jungle some of the creeps that respawned again. Or if you feel the enemy team wont gank you, you can try to farm the buffs from the enemy side.

Be sure you get your boots as soon as possible now

Once you get lvl 6 you can help your team gank the enemy at their lanes. Your ulty will finish or nearly finish enemy low health champions and if its not enough use your hungering strike which does a lot of damage too.

From now on just jungle and come help gank some people when you got your ulti or whenever you feel you can kill some people without getting killed yourself.


Last Word

I hope you like my guid. If you have anything to add or got some hints for improving be my guest. I am open to suggestions. Have fun playing warwick !

Jungling is evil, costed me around 200 matches ¬¬

-Fami ^^

This is a very bad guide. 2/10 for trying.

Well , soso guide , Hunters mark should stay level 1. Bloodscent is like ghost in every teamfight. WW has many ways to be played. You can get long sword and 1 potion isntead of cloth armor and 5 potions since it will boost your speed and u dont need more.Try it

You don't mention putting a point into archaic knowledge - 15% spell pen - which helps his q and madreds bloodrazor which is most of your damage. Extra crits are just unnecesary on WW.

WW i my main and i can only say lol at your skill order... stoped reading after that

Btw dude u have to max blood scent before hunter's call
cause u will get a huge range detection of low hp enemies and a huge speed boost and for the jungle 1 lvl of hunte'rs call is enough

Smite is a must have when jungling, speeds it up by so much and you can't have buffs, dragon and baron stolen by the enemy jungler easily.
