The Permafrost Greaves are a set of unique and incredibly powerful boots. They were given to a player for sacrificing 30 Plated Greaves, which was one of the tasks given to celebrate developer Papa Marsh's One Year Initium anniversary.
They are modeled and named after a piece of his developer armor.
"Frozen colder than ice, these greaves grant a superhuman swiftness in addition to a tenacious layer of protection."
