Flameskull

Flameskulls were undead sentries fashioned from the skulls of dead spellcasters.

Abilities
A flameskull's undead transformation could grant it full access to the magic it wielded in life, letting it cast spells while ignoring the material and somatic components it could no longer employ.

Description
Flameskulls were disembodied floating skulls wreathed in green flame.

Desctruction
If destroyed, a flameskull's shattered fragments would reform unless they were splashed with holy water or subjected to a dispel magic or remove curse spell.
