I was adventuring in the wasteland with a X-01 power armour thinking that nothing can be a harm to me until I faced a big scorpion and his attack was poison damage which killed me in seconds, so that was the reason I decided to make this power armour that can resist all types of damage and none draining fusion core. This power armour can resist grenades, mines and even nukes.

This is a standalone power armour and you have to craft it at the chemistry station under utility.
