The Submarine is a submersible vehicle in Rell Seas that allows users to travel stealthily from one location to another without the interference of other seafarers. Along with that, it also protects against various sea creatures that usually tend to attack ships traveling on top. Speaking about the appearance, the entire vehicle is coated in black and has a rusty texture. Also, from the image, you can easily find a periscope attached to the top of the Submarine that may allow players to spy upon other ships on land or scout for new islands.
