For conquest go Warrior's Blessing + Chalice and 3 or 4 Healing Pots. For other modes Warrior's blessing + Round shield + 2 Healing Pots and 1 Mana Pot start.

These are your cores, a must have in almost every single mode. Soul Eater can be implemented anytime in your build. Soul Eater is a substantial item on Sun Wukong; similar to Glad's Shield, this item procs on all his abilities to lifesteal like crazy. So Soul Eater combined with Glad's turns you into what others call "Vampire."

This is a frequent build to have in mainly conquest, Full CD reduction with antiheal in case enemies have tons of lifesteal or heals which is pretty frequent. This order can be swapped if against more magical gods than physical gods.

In my opinion, Hide of the Urchin comes in later because as a Warrior class you rarely fight to obtain assists/kills during laning phase. However, mid to late game most definitely.

Soul Eater is put before Hide of the Urchin because Soul Eater is much easier to stack, this item can be put behind your second defense item, for example, pestilence. Soul Eater can also be bought early if ahead and you just want to output some more damage.

Pretty similar to the conquest build, however Mantle of Discord instead of Hide of the Urchin and Brawler's or Crusher* would be a replacement of Glad's Shield. Reason is first, it would not be needed anymore having full stacked Soul Eater and second, Mantle of Discord would make your CD reduction past the max CDR. You would end up with 130-140 physical power with a good amount of mix defense with Breastplate, Bulwark, and Mantle of Discord.

*Would highly recommend Crusher if Brawler's is not needed due to the enemy team having small amounts of heal. Crusher's passive procs on all of Wukong's abilities.

Void Shield and Ancile has been the items for Warriors to shift their usual tank to a bruiser. It provides a good amount of dmg along with an adequate amount of defense. These two items can be replaced with any of the main defense items, for instance, Breastplate of Valor, Bulwark of Hope or even Glad's Shield.* Mantle of Discord can also replace Glad's if needed for more defense in conquest.* Blackthorn Hammer, the not-so-new item that has made mostly every warrior and some assassins seem extremely strong due to it's power boost with health and mana along with the amazing passive. Blackthorn Hammer can be replaced anywhere in Wukong's builds besides the core items, excluding Glad's Shield. It can replace Glad's Shield's 10% CDR with more bruiser potential.*

*In conquest, I would replace Glad's Shield with care and only replace if necessary.

Why Void Shield instead of Shifters? Void Shield just provides that good balance between physical protection and health along with 20 power + small penetration. While Shifters provides a ton of power, lacks in defense. Yes you get 35 protections of each being below 50% but when you ult and heal it's going to shift from defense to power. Shifters would be really situational in terms of how farmed you are.

Why Ancile instead of Runic Shield? Ancile's passive is just amazing, silencing enemies while taking dmg from a magical ability. This item also provides a little more power and 10% CDR along with its passive! Runic Shield can come in handy to lessen the damage of mages when you are in their face but what's 50 power less during late game? While it gives you 150 health, I wouldn't prioritize that and its passive over Ancile. You can build if Ancile's silence is pretty much useless on the mage you're fighting then Runic would be the replacement for Ancile.
