Venomdust - Dragon

Wizard's Spell Compendium Version

The venomdust spell enables the dragon to create small amounts of highly toxic poisonous dust. The dust can then be sprinkled onto objects, where it adheres. Anyone touching an object so treated with bare skin must roll a successful saving throw vs. poison or die in one round. Even on a successful saving throw, the victim suffers 2d10 points of damage. The dust is rendered harmless by a successful casting of dispel magic or neutralize poison. The dragon can negate the dust, making it harmless, at will.

Dragons frequently use venomdust to protect the most precious parts of their hoards.
