This is my endgame [Wukong] build, It's very expensive but it will keep you alive and allow you to get the most out of your [Iron Staff] as well.

Arcane [Guardian] will help reduce damage and Arcane Energize will keep your energy up.

With Arcane [Guardian] and Defy active you will have 2900 total armor.

You can also use an Aura Forma for more flexibility.

This build works in conjunction with my Speed build.https://overframe.gg/build/15048/
