The Vaulderie is a Sabbat ceremony in which all participants contribute vitae to a single vessel and all partake of it in turn. This creates something akin to the Blood Bond called the Vinculum, which has a rating of 1 to 10.

When the Vaulderie is shared, the Sabbat rolls a die representing each other vampire in the ceremony. The result of the roll is compared to their current Vinculum rating; if greater than the rating, the Vinculum score increases by one. If there is no Vinculum between the two, the die result is the Vinculum rating for that vampire.
