Despite the name's connection to the sea, it does not act as a diving helmet. On the Test Server of 10.7 it was proposed by several testers that this helmet allow diving underwater, since its name implies a connection to the sea and the stats were very poor at the time. Instead, CipSoft added Ice Resistance and a Speed boost to it. Can be used as part of the Speed Set. Seems to drop as often as a Royal Helmet from a Dragon Lord.
