Unburden the Bestial Soul
Legend says that vampires are cursed by Caine’s sins, their souls blackened by the very nature of the Embrace. With this power, elders can alleviate the urges and ravages of the Beast, offering a vampire’s soul an evening of rare and blessed peace. However, such forgiveness comes at the cost of a certain amount of free will.
System
Spend 3 Blood, touch a willing target, and concentrate for one minute to remove all of that target’s Beast traits. After being consecrated in this manner, your target is incapable of taking any action that would cause her to gain Beast traits for the remainder of the evening. If your target attempts an activity that the Storyteller believes might lead to a Beast trait, the character loses her action without performing the activity.
