Hello there, my name's Therux, and this guide is to show how I play Warwick. He excels as either a jungler or a solo-top champion, and should be played as either. This build is specifically for jungling.

Full Size Here

Pros:
-One of the strongest junglers
-Easy to use
-Great sustain
-One of the best chasers
-Great on-hit ap dmg + physical.
-EXTREMELY powerful ult

Cons:
-Ultimate can be disrupted
-Quicksilver sashes
-Vulnerable to stuns/blinds
-More item-dependent

For runes I go with Armor penetration quints and marks, attack speed glyphs and armor seals. Using this setup, the monsters you jungle against wont have any armor, and most champions will have little to no armor until mid-late game.

20/10/0 is my favorit way to build warwick. You get all the CDR/AS/APEN/MPEN/Lifesteal.. everything warwick loves to have. Then the armor/magic resists and jungling masteries from the defensive tree.

A MUST: and . There are no other options here. WW has no escape mechanism, and flash is the best way to get out. Also, in chasing an enemy, you can flash + ult... it's range is decepticon and will have other champions saying WTF!!>!?

Hungering Strike Takes a bite out of enemy unit and heals Warwick.
Strikes an enemy for the greater value between 75/125/175/225/275 (+1) and 8/11/14/17/20% of the target's maximum Health as magic damage (can only do flat damage to monsters), and heals Warwick for 80% of the damage dealt.

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.
Toggle: Warwick senses enemy champions under 50% Health within 1500/2300/3100/3900/4700 distance of him; while he detects a low-health enemy, he gains 20/25/30/35/40% Movement Speed.

Infinite Duress Warwick lunges at an enemy champion, suppressing his target and dealing magic damage for a few seconds.
Warwick lunges at an enemy champion and supresses them for 1.8 seconds. During this time, Warwick attacks his victim 5 times dealing a total of 200/300/400 (+) magic damage (every attack applies on-hit effects).

Warwick gains 30% Life Steal for the duration.

Eternal Thirst Each of Warwick's attacks will heal him. Each successive attack against the same target will restore increasing amounts of health to Warwick.
Bonus-per-hit starts at 6/12/18 and increases by 6 at levels 7 and 13. See mathematical breakdown for full reference.

Goals in priority order:
Max Ultimate
Max Q
Max W
Max E

I find it beneficial to get 1 point in blood scent at lvl 5 to help with ganks.

ALWAYS start with cloth armor, and how many pots you think you'll need. With my warwick, I NEVER take pots on TTL or SR. He just doesn't need them.
Madreds asap > boots > Vampiric scepter > Wit's end. At this point, you are at Warwicks core build. From here, build as you think is necessary. At this stage, your resists are relatively high for this point of the game, and you have great sustain.
Core:

Vs heavy AP


Vs heavy AD

TTL: Start at closest camp in mid-jungle, then go to the opposite side camp, use smite. Teleport back, go to upper jungle and kill closest camp, then use smite on whatever buff it is (Green or white). You now have enough for madreds... go buy it, get red buff, then have top lane help you with dragon. Now jungle some more until you get 6 and win.
SR:
1- If you're new, it's a must to start at blue. You don't need a leash if your teammates are busy/rude. Then work your way down the jungle, to wolves / wraiths / red / golems. Get madreds ASAP and keep farming until you get 6. It's not reccomended to gank until 6, unless the enemies are overextended.
2- If you feel comfortable with taking dragon at lvl 5, do golems, wraiths, wolves, blue, golems, wraiths, red, dragon. (Make sure you have madreds)

All in all, Warwick is a very fun champ to play. Try the builds out before any criticism. This build works for me, and hopefully it will work for you too.
