Bottom Feeder. While attuned to this coat, you can breathe underwater and your movement speed is not halved when swimming. Additionally, you may expend all of your movement to ascend or descend 90ft. in a straight vertical line underwater.
Part of Your World. When you are underwater, you have advantage on all Stealth checks as the organic parts of this coat obscure you lightly from vision.
