Crimson Tithe

Pay the altar exact tithes of 4, 8, 4 and 16, then leave an eight-strength heir in the central crypt. Select a vampire and tap a neighboring crypt to move or fuse an equal vampire. Offer sacrifices the selected vampire only when its value matches the current tithe; a new strength-2 fledgling awakens in that crypt. Feed doubles the selected vampire, spending blood equal to its current strength. The cellar holds twelve blood, and every offering also spoils one blood. Feeding, moving and offering each spend one of eighteen night actions. Do not sacrifice your whole bloodline: the final heir matters as much as the altar.
