Bloodstone's spectral steed

Bloodstone's spectral steed was a necromancy spell used by wizards. This spell was developed by Bloodstone.

Effects
This spell created a spectral creature resembling a vulture capable of flying the caster and their companions about. The caster needed to name all passengers at the time of casting.

The spectral steed uttered ghastly screeches while it flew. Natural creatures shunned the spectral steed and only monsters would dare attack it. The steed did not have any form of attack and would vanish if destroyed.

Components
In addition to verbal and somatic components, this spell required a hollow bone from a vulture's wing to cast. The bone needed to be carved into a whistle and blown when the spell was cast.
