Flameskull

Basic Information:
Blazing green flames and mad, echoing laughter follow a disembodied skull as it patrols its demesne. When the undead flameskull discovers trespassers, it blasts the intruders with fiery rays from its eyes and dreadful spells called up from the dark recesses of its memory.
Flameskulls are fiery undead guardians fashioned from the skulls of dead spellcasters. Stronger varieties are known as great flameskulls. A flameskull is created from the head of a humanoid (usually human) spellcaster shortly after he or she has died.It needs to be fresh. They are made by dark-hearted spellcasters, typically a cleric or wizard using a create undead spell, but the precise rituals for creating them are very old and even long-forgotten. They can choose whether or not the resulting flameskull can cast additional spells. Flameskulls obviously can not reproduce or replicate themselves. Once the ritual is done and the transformation complete, the skull burst into green flames.
