Ward your non starting buff first with the vision ward then run to your starting buff. I like to start blue but i typically always favor a Bot lane leash as its faster and the better clear is great. typically I'll do Blue->Frog->wolves (scuttle if im not power farming) Red/raptors (if you did scuttle its pretty time consuming youll want the blue buff to keep your Q up on raptors theyre mean this season) then scuttle/gromps. I skip scuttles if im power farming to 6.
this point ill run back to blue side and get frog+wolves again. this is my first back. on your return start looking at lanes youre going to be hitting 6 after 1-3 camps. PING talk let your laners know where youre going. focusing bottom is fine for dragon control always watch where the enemy jungler is and hit those vision plants as much as possible.

depending where Iam at i might pick up an early Cinder (fire part of sunfire cape) this help with warwicks clear and also buffs your keystone nicely (CoC shield). at this point you should also be scanning the enemy team for what boot upgrade.. lots of CC? lots of AP? .. get Mercs.. your laners need lots of your help? swifties to run to em pronto (maxing E 2nd aids this too)..things are kinda going okay not much CC not much AP get the CDR boots, for that quicker Ult

At this point you should have a good understanding on whos carrying the enemy team and what items you need to build to resist that. if youve been ahead and they had AP I assume you have a Witts End, Bloodrazer, and a boot up grade of your pleasing. now if youre ahead and theyre AD i would sub witts for BOTRK as its been buffed nicely. If youre even or behind tank items after blood razer, sunfire cape/spirit visage are core spirit first if theyre AP mostly, sunfire first if AD

now if you have taken a big lead at this point go ahead and build witts or botrk other wise
pick up a nice Guardian Angel. this item is OP on the Wick. youre 50hp you ult, you die mid ult.. youre doing damage STILL, youre healing STILL, then when GA brings you back you have even more health and theyre stil hurt, then lastly snag a witts/botrk
a damage item last will keep you effective and you wont fall off you can still be beast wick and eat everyone

Now if you read this far theres some other items that work well on the wick like black clever, its hard to get kited and is proct with your ult and works with blood razer and Blade of the ruin king. Titanc hydra is nice as well as your ult procs this and if theyre mostly a melee team its great you can hurt them all at once instead of one at a time king of 1v1 becomes a God at 2+v1
