Most rocks are basic, run-of-the-mill objects. They're found everywhere on most planets, have little to no intrinsic value, and are about as ordinary as... well, a rock. Then, there are these. A rock of limitless water is a rock, stone, or other similar object that emits a steady stream of water from itself. Such an item is generally held as an object of reverence, either from a deity, other mystical force, or perhaps something more sinister. These items are generally desired for their otherworldly powers by heroes and villains alike.
