Power Armour

Power armour' was a form of protective gear available on Earth's alternate time stream as created by Minax's interventions in Ultima II. It was the most powerful armour of that era and has not been replicated since.

Description
Much like the contemporary reflect armour, little is known about exactly what comprised a suit of power armour. Appearing only briefly in the course of the Stranger's adventures, power armour has long since faded from the fabric of modern Terran reality, likely having vanished with the Death of Minax. It is known that in addition to providing the wearer with significant defenses against the toil of melee, power armour was suitable for use as protective gear during space travel, much like the  vacuum suit.

Trivia

 * In Ultima II, a Strength statistic of at least 31 is required to don power armour.
