Fractal Sponge
--------------
Rarity: Rare
Aura: Transmutation
A fractal sponge is an object slightly larger than your hand that has the structure of a Menger Cube, and can absorb arbitrary volumes of water.
When submerged, a fractal sponge absorbs one gallon of water per round, or about an hour and a half to absorb a 5ft cube of water. This does not affect the weight of the sponge.
The water is inaccessible once inside the sponge; it is permanently dry.
The sponge can absorb any liquid, however things such as lava and acid will damage the sponge as normal.
The sponge has 5 HP and 12 AC.
If destroyed, the sponge folds in on itself and dissapears from existence.
