Diving The Diving skill allows a player to swim assisted down to depths lower than around 10 metres. It is also a requirement of the Caving skill. At base level, a diver can swim assisted to a depth of 10 metres – the same depth as a swimmer or freediver, but with the ability to use underwater breathing equipment. At Instructor level, a player can teach the skill to others and dive to a depth of 40 metres. At Artificer level, the player is able to construct underwater breathing equipment, goggles, lights and other diving equipment.
