The Helmet of the Deep is used to dive underwater. Wearing it is required to be able to go underwater, but once there the helmet can be removed. However, without it players will take 5 times 20 Drowning damage kicking in after four seconds of standing still. It is useful out of the depths, too: some monsters, like Water Elementals, use drowning damage attacks. There is a 5,000 gp deposit for the helmet. You must be a member of the Explorer Society (beginning of the Explorer Society Quest - The Undersea Kingdom) and have at least the Rank of a Relic Hunter/Huntress to rent one. Renting one is not bound to any liabilities and you may return the helmet by saying 'return' to Captain Max.
Players above level 150 may opt to use the Depth Galea instead, which has 6 more armor points and weighs 164 oz less.
