You have a spawning pool of your own (or possibly donate heavily to the Clan’s main pool). Creating such a pool takes time, and requires regular infusions of blood, at least six blood points a week for a year.

The Merit grants its level as a dice pool bonus to the Nosferatu’s use of Animalism in their home city, but only with animals considered vermin, such as rats and cockroaches. Essentially the bonus is only available for creatures that might conceivably drink regularly from the tainted blood.

Once established, the spawning pool requires twice its level in blood points each week to it. Without proper maintenance, its level will drop by one. It can be rebuilt by maintaining it at the new level and adding four additional blood points each week for six months.

The Merit cannot be improved above its initial level, as this also represents the convenience of its location and the variety of creatures that might find it.
