Warwick is a very weak early game ganks, but get a lot stronger once he hits level 6. Warwick is an easy jungler to master so if you are looking to try a jungler I would recommend starting off with Warwick. My jungle pattern is very simple, start red work your way to either wraiths or wolves whatever is closer and then go though the mid tier 1 and 2 towers, once again get the wraiths or wolves whatever side your on, blue or purple, and then get blue. By this time your red should be just a couple mins. from respawn, so kill some time by ganking top/bot.

For runes I got Attack Damage Quints and Marks for stronger ganks, armor seals for better sustain in the jungle and magic resist glyphs for counter jungling.

For warwick I like to go for AD offensive items and tanky defensive items. At the end of the game my build is Frozen Mallet for the at and health, Trinity Force for, once again, the AD and health, a Blade of the Ruined King, for the active so when I gank I can do some extra damage, boots are really your choice, either ninja tabi, or berserkers greaves, but always upgrade to home guards when you can, just for the extra health regen I'll go for a warmog's armor. To finish it off for the AD I'll grab a Infinity Edge for massive damage.

For skills your best bet will be to grab your w for the attack speed first if you are getting a leash. If not then your best option will be to grab your q. Either way at 2 grab either w or q whatever you didn't get at level 1. 3 grab e, and then max your q first maxing w second, e third, and the ult at the normal levels of 6, 11, and 16

For masteries I go 9/15/6 focusing on attack damage in offense, and sustain in defense and utility

Early game is the weakest for Warwick as you need a load of gold to set up for mid/late game. So the best thing to do is just farm the jungle until you hit level 6. If first blood has not been drawn yet try to gank to earn/assist in first blood. Go back and farm the jungle ganking lanes when they need it.

Aside from Wukong (I will be doing a jungle guide on him later) at level 11 warwick has the biggest power spike in the game in the jungler section. So try to take advantage of this and gank lanes trying to farm for xp as well. Once again you won't have much HP yet so try to farm jungle for gold setting up for late game.

Late game is really simple if you set up for it correctly by farming the jungle and lanes as you gank. If you a tank with AD as well, start the fights with your ultimate focusing the squishy ones, tell your team to focus someone else. You AD with your w, e combo will destroy the champions health bar. If you have gone for a tankier build then let someone else start then follow up with your ultimate

Please keep in mind that this is my first guide, so any help you can give to me in the comments section would be greatly appreciated. :) - RetryoGamer
