Hi! I am Ixoss, and I'm new on Mobafire. It's my first build, but I want you to be frank. I'm from Poland, so I can make some mistakes. Sorry for that.

Warwick is a really nice champ, his passive gives him something like lifesteal, his Hungering Strike can be used to esily get kills or to survivie hard fights, and his Blood Scent and Infinite Duress makes you a killing machine. There are two versions of build: build which I use, and build suggested for normal laning, especially solo topping.

Pros: + Good lifesteal + Nice survivability + Easy and fun to play + Great ganks above level 6 + Chasing enemies with Blood Scent

Cons: - Self-stun ultimate - Mana hungry before buying mana regeneration item - His ultimate can be stopped

This is my runes setup.

Greater Mark of Scaling Attack Damage: It gives you AD, so it means more damage
Greater Seal of Attack Speed: Gives you some attack speed, which is also important on Warwick, because you can steal life or kill faster
Greater Seal of Scaling Attack Damage: Just like in Mark of Might
Greater Glyph of Scaling Attack Damage: Like up
Greater Glyph of Attack Speed: Giving attack speed
Greater Quintessence of Life Steal: It gives you lifesteal, which makes you real Warwick.

This is suggested rune setup.

Greater Mark of Scaling Attack Damage: It gives you AD
Greater Seal of Scaling Attack Damage: It gives you AD too (it's surprising, isn't it?)
Greater Glyph of Scaling Attack Damage: It also gives you AD!
Greater Glyph of Attack Speed: That rune gives you attack speed, I explained why it is important before.
Greater Quintessence of Scaling Attack Damage: AD...

I use Ignite, because it can be used to easily get First Blood in early game, and to kill fleeing enemies in all moments of game. It can also be used as Anti-ks protection. I also choose Flash, because it's one of the best spells in the game - it can be used to flee, pursue, gank or something else. You can replace Flash with Exhaust. It makes easier to solo someone, because it lowers his damage, and it also can stop fleeing enemies, but it can be stopped with Cleanse or Master Yi's Highlander, and that's why I use Flash.

Q: Hungering Strike: Really, really good skill. It attacks with some dmg + your AP OR some percent of target's maximum health. It also heals you 80% damage done. It can save you, it can give you a kill, it can deal a very high damage. Really comprehensive skill.
W: Hungering Strike: It gives you and nearby allies boost to attack speed. Really good when soling something, great when doing solo Dragon or solo Baron, great when pushing turrets, and really, really great in teamfights, because all your allies have buff. It also helps you when you're ganking someone, because you can kill him faster.
E: Blood Scent: Skill that didn't need to be maxed. Just one point at level 4. It makes you a killing machine. When enemy has low health, you see him, even, when he is hiding, and you have movement speed boost. When somebody with low health hears Warwick's cry, he can only pray...
R: Infinite Duress: Your ultimate attack. It makes you jump on your enemy, stun him and deal 5 hits. When using this attack, you gain 20% lifesteal, and your 5 attacks triggers on-hit attacks (like Madred's Bloodrazor), which makes this skill a really dangerous attack. Perfect for ganks, but you shouldn't initiate a normal fight with it. It should be used to kill fleeing enemies.

I start with Doran's Blade because it gives me lifesteal, health and some Attack Damage. Perfect for beggining. You can begin with Boots and 3x Health Potion, especially when going solo top, but damage boost better fits to my style of playing.

After Doran's Blade, I build Berserker's Greaves, because it gives me movement speed and attack speed, and I think that this is the best boots to choose on Warwick. Then I buy Wriggle's Lantern, because it gives AD, Armor, Lifesteal and additional damage to minions. Then I buy Chalice of Harmony, mainly because of Mana regeneration bonus, because Warwick can be mana hungry. After it, i buy Madred's Bloodrazor, because of AD and great on-hit effect, which makes your ultimate a lot deadlier and stronger, and it's very effective when fighting tanks. Then, I buy Bloodthirster, because it gives you a great lifesteal and AD (especially when stacked). The last item is Phantom Dancer, because of great attack Speed. After completing build, you will can easily do solo Baron without losing even half HP, and you will be also nearly immortal.

But in suggested build, after Boots and three potions, you should buy Doran's Blade, because of AD, Health and lifesteal, which grants you more survivability at the beggining. After it, you should buy Berserker's Greaves, it gives you attack speed, and it's the best boot for ww. Then, you should buy Wriggle's Lantern, because Armor, AD and Lifesteal, and it can be used as a ward. It's a really nice item. Then, you should buy Recurve Bow, later, you will build Madred's Bloodrazor from it. Then, you should buy Frozen Heart, because it grants you Armor, which, in conjuction with your great AD and lifesteal, makes you really strong in teamfights and in 1v1 fights! Then, you should build Madred's Bloodrazor, then Guardian Angel, armor, magic resistance and it's ability to revive you is really nice, because you will be focused ine teamfights. And finally, Trinity Force, because it gives you boost to AD, AP and AS, and it also gives you slow effect, that is triggered on your target when you use your ultimate, so it's a perfect ending item that.
