Cloak of Rat Speed is a magical item that grants speed to the user.
Contrary to its ragged appearance, this item is far from an ordinary cloak and is considered an unimaginably powerful magic item in the New World.
At first glance this cloak resembles a simple grey blanket, which disguises its true value.
The cloak allows for increased movement (travel) speed, agility and evasion.
