[Wukong] mains, rise up! This build is primarily focused on doing nothing but braindead gameplay. You simply cast his 1 for his twin to kill stuff for you, then cast your 3 for bonus 1500 armor, and your 4th for either more armor (cold), more reload speed/holster speed (toxin), more health (heat), or more shield capacity (electricity). Ideally, you'll want to use heat for more health or cold for more armor.
This build works best with the [Kuva Bramma] since the twin can easily kill enemies for you, a status primer [Kuva Nukor] so that you can apply status on enemies for more damage, and a hybrid [Kronen Prime] build to take advantage of those status effects from the [Kuva Nukor].
