So I've picked up two pieces of legendary chest armor. One is marked Cavalier's, and specifies a damage reduction of 15% when blocking or moving (maybe sprinting?) The other piece I have is marked Powered, and says that it increases Action Point refresh speed. Problem is, it doesn't specify by how much. And add to my quandry the fact that I already have a Powered leg piece, as well as one perk point invested in Action Boy. Tried looking "Powered" up on the Fallout wiki, and got no more information than is in my Pip Boy.
So does anyone know how much Powered refreshes your Action Points? Would it stack with my other piece of Powered armor? Does it stack with Action Boy? Is it worth sacrificing for Cavalier's armor?
