Fallout 4 Legendary Power Armor – Piezonucleic Chest Armor
There are a variety of different models of Power Armor available in Fallout 4, which can be tricked out and modded to incorporate numerous features and benefits. Power armor is rare and powerful, and thus highly sought after amongst the commonwealth wasteland denizens. Even more rare and coveted are rumored legendary pieces of power armor, which have even more unique bonuses and perks.
The Piezonucleic Power Armor chest piece is one such item. Located at the Cambridge Polymer Labs, the Piezonucleic power armor can be obtained by combining certain elements with a breakthrough isotope. The ingredients needed are lithium hydride, gold, and the isotope U-238. These elements, as well as some other chemical reagents, can be found throughout the various rooms in the Cambridge Lab.
Fortunately, the lab is relatively small and the reagents easy to find. There are a number of ghouls to contend with, but once you take them out you should be fine. The correct placement of the chemicals are: lithium hydride far left, gold middle, and U-238 on the far right.
