(Based on the Traitor's Dagger artifact from the Dark Age of Camelot MMORPG)
Deathcloud is a +3 dagger, with a curved, jagged blade. It radiates light equal to a Light spell when drawn. On a natural 17 or better to hit roll, it casts the Vampiric Mist spell against the creature it just struck. It must be a living creature, capable of bleeding,to activate the function. The Vampiric Mist spell lasts for 15 rounds, more than one can be active at a time and the wielder is healed for half the amount of damage that the Mist inflicts. Claimed by Ulayoth.
