Hello Mobafire! I've made this guide to share how I personally play tanky Warwick. With that said, this build has room for changes. I believe that this Warwick build can allow for great sustain and decent damage as well, this guide will high light my favorite way to play. I'm not a professional gamer, I'm just one who enjoys league of legends.

Warwick is an awesome assassin type who has great dueling and sustain abilities. The point to Warwick is to be like a wolf, sneaky but yet aggressive. Early game you play more one the passive side while the build progresses, don't take to many risks. As late game comes you can be more aggressive and start focusing the most dangerous champ on the enemy team and also tanking for your team.

Expect to take time and practice, as with most champions. Very few people can pick up a new champion right way. If at first you don't succeed, try again!

Anyways, my name is Joe. Enjoy my guide.
P.S. this is my first guide so if there are any suggestions feel free to let me know. Friendly advice is wanted.
Oh and I don't know how to do all that fancy stuff to my build guide yet but hopefully I will learn eventually.

Pros decent mobility Great ganker once lvl 6 ( Infinite Duress) very nice cc on ult good sustain damage great passive life steal ( Eternal Thirst) great attack speed buff ( Hunters Call)

Cons not to good early game quite mana hungry bad early ganks when jungle people blame you often take intelligence at times

Starting Items

Personally I recommend boots and 3 pots but if you prefer or feel something else go for it because the starting items are not end all be all.

Item Break Down

Reduces stuns and other things of similar nature and gives magic resist which is nice.
*but if the enemy team does not have much cc or ap/ their ap carry isnt doing well adjust for that and feel free to get what ever boot you think would work the best in your game.
As a tank you need magic resist and i feel this is the best magic resist item for warwick due to the attack speed. I get this first just for that reason, attack speed. "The sustain on WW is great early game in general. Hard to get a jump on him in jungle if your low on health, and hard to get away if he has red or your low health due to his free speed boost Blood Scent. Also Wit's end does on hit damage, which means the passive magic damage activates 5 times when he ults Infinite Duress, so Wit's End is even more useful than just the MR.
This is great because it gives damage, slow, and health. Once you have this item not many people with be able to run away, especially when they are low because of your e. Also this is when your ability to tank starts to become noticeable.
This item adds to your health and armor. After this item is complete tanking should be relatively easy. Now you have solid health and good armor and magic resist.
If this game happens to last this long it is good to get this item because it add to your sustain do to the life steal and give you more damage. Also when activated it give you a speed buff and the enemy the ability was activated on a speed debuff, the speed boost is similar to Blood Scent.
If the game happens to last this long it is great to get Warmog's Armor due to the extreme health increase. Now it is not necessary to rush Warmog's because they took the slowly building it up process. Now its finally official there isn't much to worry about, you should be able to tank for days with the build complete.



Consumables
Once your main build is complete all that is left is consumable and dont for get the boots now have an upgrade so do that too.
Oracle's Elixir
Elixir of Brilliance
Elixir of Fortitude

This is still a work in progress, not the build itself but the guide. In other words I will eventually make it look better and more organized and more in depth. I might even add some cool little icons but for now this is all I knew how to do.
