Star Vampire CR 9
There is nothing before you but a chittering that tickles your ears, sending unwanted waves down your spine. Slowly, a swollen creature with huge talons and covered in masses of sucker-like proboscises comes into view, redly, for only where the blood inside of it sloshes around its form can you make out its shape.

Bloodless Invisibility (Ex)
A star vampire is naturally invisible at all times, even when attacking. This ability is inherent and is not subject to invisibility purge. Against foes that cannot perceive it (through blindsight or a similar ability), the star vampire gains a +20 bonus on Stealth checks when moving, or +40 when standing still—these bonuses are not included in the statistics above. A star vampire becomes visible when it uses its blood drain special attack, and remains visible until it uses its digest blood ability.
Digest Blood (Ex)
As a standard action, a star vampire can metabolize all of the drained blood in its system.
This heals the star vampire of 4d8 points of damage (regardless of how much blood it drank) and allows it to return to its normal invisible state.
Drain Magic (Su)
When a star vampire successfully uses its blood drain attack on a spellcasting creature or a creature with spell-like abilities, the creature must make a successful DC 17 Will save or have some of its magic drained away. If the creature is a spellcaster, one prepared spell or unused spell slot (randomly determined) is lost.
If the creature uses spell-like abilities, it loses the use of one spell-like ability. A creature that has both spellcasting ability and spell-like abilities loses spellcasting ability first (in the form of spell slots of prepared spells), and only loses spell-like abilities if all of its prepared spells or spell slots are used up or drained. Drained prepared spells can be prepared as normal the next time it recovers spells.
A star vampire is constantly surrounded by a disturbing, high-pitched tittering that seems to come from everywhere at once. This sound baffles attempts to pinpoint a star vampire; whenever a creature attempts to pinpoint a star vampire it must roll its Perception check twice and take the worse of the two results. This is a sonic effect.
Naturally invisible, the first sign of these creatures is typically a strange, high-pitched tittering sound that seems to come from everywhere and nowhere. As they feed upon the blood of their victims, that blood itself remains visible and gives the creatures a perceivable form. Since each star vampire is effectively covered in mouths, any part of a star vampire’s body can drain vitality and magic from its victims. One end of the creature may protrude in a sort of head-like mass, but it has no visible sense organs or emblems of its status.
Star vampires are completely invisible in the normal visible spectrum and can walk on the ether of space.
They are 10 to 16 feet in length, and gravity does not seem to affect them.
