Yves le Prieur’s Diving Mask

Origin
Yves le Prieur was an officer in the French navy who invented the scuba diving system with help from fellow inventor Maurice Fernez. Similar to Fernez’s design, oxygen was pumped to the diver from the surface, but le Prieur’s full face mask would balance out the pressure inside the suit.

Effects
The helmet will envelop the user in a correctly pressurized scuba suit when it touches water. Even though filled with breathable air, the person must remain close to the water’s surface to maintain the effect.
