R: touch; T: object; D: [sum] hours
You touch a stone no larger than your head, and it grows a face like a gargoyle. You can designate [dice] conditions under which the stone will discharge water. The conditions must be obvious, as the stone is not very observant.
Water is sprayed by the stone in a [dice]x5 ft cone. It deals no damage, but has a [dice]-in-4 chance to extinguish torches. The water disappears once its 100 ft away from the stone.
At 3 [dice], creatures passing through the cone must Save vs Might or be knocked prone.
