The Diving Gear is an accessory which allows the user to swim and breathe underwater for an extended amount of time. It combines the functionality of the Flipper and Diving Helmet. Apart from combining the two effects into a single accessory, it does not have other unique properties.
Like all diving equipment, the Diving Gear prolongs the underwater breath to 1minute and 33.33seconds or, while holding the Breathing Reed, to 3minutes and 6.67seconds. In addition, the rate at which health is lost while drowning is reduced to 1/4 or 1/8, respectively. While it is possible to equip multiple pieces of diving equipment, doing so does not cause them to stack.
The Diving Gear is one of the few items that combine a piece of armor (Diving Helmet) with an accessory (Flipper). This allows equipping a complete armor set, which usually grants a set bonus, without having to go without the single piece's functionality.
Note that while the Diving Helmet, one of the ingredients, grants +2 defense, the Diving Gear does not grant any. Contrary to the Diving Helmet, however, the Diving Gear may gain modifiers, being an accessory, potentially granting a +4 defense bonus if obtaining the Warding modifier.
