This two-piece legendary armor set, comprised of the Mantis Left Greave and the Mantis Left Armguard, is certainly one of the best in Fallout 4; however, it is so rare that most do not know it exists.

Fallout 4 has five standard variants of power armor, from weakest to strongest — Raider, T-45, T-51, T-60, X-01. Each suit of power armor has six parts — a torso, a helmet, two arms, and two legs.

Found in what is arguably the best-written side quest in all of Fallout 4, The Silver Shroud, you get to play vigilantly in Goodneighbor with your silver submachine gun.
