This is an easy guide, based only on Items, skills sequence, runes and masteries and spells! Using this build you will never loose a game with a score of s**t ^^

If you think that this runes are crazy, try to play with them! I think that runes help you only at the beginning, and with Ability Power, Magic Penetration and Mana Regen you can spam your Q and do a lot of damage without loosing life!

Classic masteries for a killer, cause i want to get kills, and i need some help with Magic and Armor Penetration (Offense). In Utility I put this masteries for Buffs, Warwick need a costant blue baff to spam his abilities, including ultimate.

At start that is too hard a blue baff without a pull and smite, you need Doran's Ring, for mana regen and a bit of AP. You need Cooldown Reduction and at the same time Health, than what is better of Kindlegem? Upgrade it with Zeke's Herald for Lifesteal and Attack Speed (and with this item you will be a bit support xD) and after get a Spirit Visage, a very nice Item on WW. Madred's Bloodrazor it's fundamental on this champ, mainly for his ulti! Wit's End will make you more aggressive, and at last a Phantom Dancer for Movement and Attack Speed! According to how is going the game you can get some other Item for Defense!

A nice couple is Warwick - Gangplank! Their Q skills will bore a lot yours enemies, and at level 6 you will get an easy kill (probably).
