Power Armor Frame

The power armor frame is a piece of armor in Fallout 4.

Characteristics
The power armor frame is the base on which all power armor parts can be added and requires a fusion core to function. The base frame provides a boost to Strength, Damage Resistance, and Energy Resistance, even without any armor added on.

Bugs
If you try to modify a Power armor frame that has no pieces on or in your inventory, you can become stuck in an inescapable animation loop. The only way to escape it is to reload an earlier save.
