This is the second draft of the wilderness section of the ocean.
The Wilderness Ocean is the most dangerous and rewarding part of the swimming skill. To swim through the rough waters of the wilderness requires a minimum of 55 swimming for the surface. The mid depth requires 65, and the deep waters require 75. Because it is in the north of the world map, the waters are freezing cold and will slowly sap your stats, at a rate of one level per minute. There are also many dangerous animals lurking in the water. Great white sharks are in abundance, as well as killer whales and even polar bears near the polar region. Because the currents change so frequently, there is no map of the currents for the wilderness. Their lack of recognition does not stop them from smashing innocent travelers up against the jagged rocks of the coastline, however. The northern edge of the wilderness is lined with steep cliffs. To get to the water one must dive down. Fortunately for divers the water by the wilderness is deep enough to allow for this... that is if you can reach the water. Sharp jagged rocks litter the water, and collision with them is almost certain death.
There is only one point of interest in the wilderness waters for swimmers. The underwater caves. As water slammed into the rocky cliffs caves during the great melt in the Second Age were formed. These caves were eventually carved into enormous caverns. When the receded the caves remained, along with a massive underground lake, stretching the length and width of the wilderness. There are varying requirements for the different entrance points to this cavern from the sea. The easier entrances require only 60 swimming, but upper level caves can have requirements stretching into the 90s. The higher the cave level the more rewarding the results. The highest level caves will have large deposits of concentrated mithril and adamant, as well as occasional non-concentrated rune rocks. Rock monsters, however, will not be down here. Instead there are aggressive slayer monsters, ranging in difficulty from 30 to 92. Other features of this system of caves include new special fish, a wide array of fossils, and the world's greatest furnace.
