Pipes of smoke monsters were ornate, magical pipes whose smoke could be shaped into the form of a creature by an attuned user. The user of these pipes could concentrate while exhaling to shape the smoke into the likeness of any creature, such as a Dragon, a Giant, or a Flumph. The shape of the smoke occupied a volume no larger than a cube 1 foot (30 centimeters) on a side for a few seconds, then dissipated.
