Howl from Beyond
Description:With 10 minutes and a bit of blood, hair or bone burnt in a candle, a vampire who knows this ritual may afflict the charred body part’s owner with the power to hear the cries and moans of the netherworld.
System: This curse lasts one hour per success rolled, and the sounds of death come across as distant and distorted. Gleaning any useful information from the din rests with Storyteller discretion. Any mortal victim with a Willpower rating less than 4 finds the experience truly maddening, gaining a derangement selected by the Storyteller.
