Mechanik’s Union

Between military salvage operations and Ordic salvagers preying on the ironclad carcasses left by the clashing of the kingdoms, there has been more activity in the depths than ever before. Which means of course, more contact with their less agreeable denizens. A fire and forget method for blocking up submerged corridors, plugging holes and inconveniencing pursuing beasties was in demand, and to some extent this explosive fulfills them. It it far larger than your average grenade, more of a large clay jug than anything. Instead of a stopper there is a small winding key for a air-tight clockwork flint striker, set to spin in approximately 6 seconds [1 round] after being wound. The impressive bit is all hidden away in layers of clay and glass. Within the clay casing is enough flashfreeze to solidify some 200 gallons or more of water. Suspended in the center of this alchemical mix are two glass containers, one within the other. The inner tube is full of spark powder and is what the flint striker ignites when it spins. The striker also shatters the inner glass tube, exposing the sudden intense heat to the mixture of liquefied true air in the outer glass tube. This in turn promotes a rapid expansion which shatters the entire device apart and spreads the flashfreeze into the surrounding environment. Freezing all water within a 10ft radius of the blast almost instantly, leaving a large rough ball of ice in its wake
