because of the massive range of acid hunter, i would stay away from the sheen. you wont be close enough to make the passive useful. also for what it does, wriggles lantern is too expensive to be useful on urgot, as he is not a jungler. lastly i would suggest building acid hunter first, then moving on to terror capasitor as the shield makes urgot incrediby tanky.

looks good. i would make it more op by putting some heavy damage item with life steal like bloodthirstier or gunblade or something. then it will double that damage as well. worth a try!

Haha, epic title!
I noticed that with this build you don't have any crit chance. Why not trade your Wit's End for an Infinity Edge?
Anyway, looks good. Hope you can write the guide soon!
