“As you progress through the zone, you’ll gain access to your very own khyek, a personal maneuverable boat that allows you to venture across the open sea,” Cryptic said. “There are several tiers of khyeks you can find in the zone that improve in speed and appearance with each tier. These vessels cannot be summoned beyond the Sea of Moving Ice.”
The sailboats — sorry, “khyeks” — have another purpose as well: to allow players to engage in some hearty deep-sea fishing. By fishing in the zone, players can haul up catches that can be exchanged for reputation, complete collections, or enhance various weapons. There are also treasure maps to be found, although these sound rare and difficult to complete.
