Kratos encounters them twice upon the icy cliffs of Mount Aroania. They attack Kratos by moving quickly, and swiping at him with their massive claws. Another power the Dredge of Boreas has is the ability to spit an icy mist at Kratos, which can freeze him where he stands. The only way to harm a Dredge of Boreas is for Kratos to first activate Thera's Bane, and slice into its icy hide while doing so. The fire of Thera's Bane will penetrate the icy flesh, causing pieces of it to break off. Beware, however, that as the pieces are removed, they will transform into Boreas Spawn (see below). Once he has stripped it of its icy armor, and has weakened it, Kratos can kill a Dredge of Boreas by grabbing on and repeatedly stabbing it in the head, followed by a final stab to the throat.
