In-game description
"This wand emits a vapor bubble that travels towards the target exploding into a deadly cloud of noxious gas that expands to fill an area roughly 20 feet in radius. The cloud will instantly kill any creature with 4 HD or less with no saving throw. Any creature within 5 to 6 HD must make a saving throw or be slain. Creatures with greater than 6 HD simply take 1-10 damage for every round that they remain within the cloud. The cloud will dissipate after approximately 1 turn."
