You summon a yellow sponge the size of your head. The sponge can instantly absorb [sum]x100 L of liquid without growing heavier. You can squeeze the liquid out, but only at the rate of a normal sponge (10 L/minute). The sponge can be reused if wrung out completely.
The sponge is impervious to harm caused by the liquids it absorbs, but you are not.
