Sometimes the Tremere need to enforce a limited form of blood bond on an agent or even one of their own, so a variation on the Ascension of the Blood ritual was developed. With Brotherhood of the Cup, a Tremere can impose such a bond, but one designed to inspire loyalty to the Clan as a whole rather than an individual.

System: While no Tremere would admit it, this ritual bears a concerning similarity to the Vaulderie. In addition to the ritualist, it requires at least four other Tremere (although tradition requires a total of seven) to put their blood into a chalice. Anyone who drinks from the cup becomes blood bound, but to Clan Tremere and what they perceive to be its goals. The effect lasts for one hour for each success gained on the roll. Once the ritual wears off, so do the effects. This does not count as having drunk once from any of the Tremere who conducted the ritual.
