You send a magical call across time to 1d2 star vampires in a nearby region of space. Each star vampire arrives under its own power by the time you finish casting the spell in a location of the GM’s choice within range. Invisible, its presence is usually first recognized by a disturbing tittering. Roll initiative for the star vampire, which has its own turns. The star vampire is generally hungry and interested in eating live humanoids or warm-blooded creatures.

With a successful DC 23 Charisma (Persuasion) or Wisdom (Yog-Sothothery) check, a star vampire can be convinced to seek out a particular creature in exchange for an immediate sacrifice to whet its appetite. If a second star vampire is present, however, it jealously attacks in response to any parley. At the GM’s discretion, a star vampire might have other interests or require other ability checks. If it isn’t convinced, it instead attacks you or other nearby creatures as it wills. However, a lured star vampire can’t attack any creature casting bind star vampire until 24 hours after its arrival.
