All participants must form a circle by tying themselves together with a silk cord. Inside the circle, the Helpless true Kindred must also have their hands and feet bound by a silk cord. The participants then begin draining the blood of the vampire as if to drain them of all their blood. The alchemist then makes a Resolve + Science roll vs. the target vampire's Resolve + Composure + Blood Potency. Each participant adds a +1 bonus to the alchemist's pool. Upon success, all participants gain one dot of their choice from one of the victim's in-clan Disciplines. They may not choose a Discipline they already have dots in. Gaining a Discipline dot in this way does not require the expenditure of experience points. Participants cannot learn or purchase this Discipline higher than the first dot. In all other respects, they can use it as though they were true Kindred. Similar to diablerie, all participants lose one dot of Humanity and gain black veins in their aura for 1 year, which are indistinguishable from those caused by normal diablerie. However, they do not gain generation or Blood Potency, and they remain thin-blooded. The victim dies, regardless of whether or not the challenge is successful.

The alchemist's blood, the blood of up to two more thin-blood participants, a silk cord, and a true Kindred who has been rendered Helpless.
