Kratos in the Icarus Vent.
With the Icarus Wings, Kratos can use the Icarus Vents that are placed around Olympus. These vents transport large amounts of air upwards, and Kratos can ride it up to different parts of the Mountain. Besides using the air to fly upwards, Kratos has used the Icarus Wings to travel a vent without air downwards as well. During his flight however, Kratos must dodge wooden support beams and flaming rocks, to ensure safe passage.
Smaller air vents exist as well, producing currents strong enough to carry Kratos upwards, but not fly. They often lead to new areas, with Kratos occassionaly having to create air vents himself, by igniting bramble pots by use of his bow, or through use of a Cerberus Mongrel.
