Infinity Sponge

I continue my Dungeons & Dragons home-brew illustration series with another original item: the Infinity Sponge.

"This magical item, when placed in a body of water such as a small lake or stream, will absorb the entirety of the liquid for one hour (after of which it will release the water and return to its original size). The Infinity Sponge can be used once per day and will drain immediately if squished.

Any creature standing within the original confinements of the body of water upon the Infinity Sponge's release must pass a dexterity saving throw to avoid 3d8 bludgeoning damage."

The Infinity Sponge cannot be moved while absorbed and cannot contain anything other than liquid. Creatures and items found within the body of water will be exposed in the ground left behind.
