Ghost Familiar

The Ghost Familiar is a recurring summon in the Castlevania series.

Symphony of the Night
As one of Alucard's five Familiars, the Ghost resembles a miniature Phantom Skull. It will hover over nearby enemies and damage them with magic. As it increases in levels it will begin to attack faster and eventually its attacks will heal you for 8HP per attack. If Alucard morphs into his bat form the Ghost familiar will look around, form three "?" above its head and will leave the screen and no longer assist you. Turning Alucard back to normal or into the mist or wolf form will have the Ghost return.

Circle of the Moon
A ghost resembling the top half of a small skeletal dragon floats near Nathan, attacking nearby foes one at a time.
