Crown of the Death Dragon

Priests of Tiamat that were also members of the Cult of the Dragon created these crowns. They grant the wearer a semblance of the power of a dracolich, at the expense of spellcasting ability.
When inactive, one of these crowns looks like the skull of a Large metallic dragon. When it is donned, the wearer appears to have the head of a skeletal dragon. The wearer of a crown of the death dragon must spend 1 round exulting in the power and negative energy of the death dragon (an imagined paragon of dracoliches). At the end of this round, the wearer must proclaim, "By the prophecy of Maglas and the might of Sammaster, I command the power of the dragon of death."
Once per day, after embracing the power of the dragon of death, the wearer of a crown summons the might of the dracolich. For the following 13 rounds, he receives a +4 enhancement bonus to natural armor, a +4 deflection bonus to Armor Class, and 13 temporary hit points. He is treated as armed when making unarmed attacks, and his limbs deal damage as if they were short swords of an appropriate size. The wearer of a crown can use his off hand to attack this way, but still incurs the two-weapon fighting penalties.
The power of the death dragon prevents the wearer from casting spells with somatic, material, or focus (but not divine focus) components, but does not otherwise hinder actions or movement.
While under the, effect of the crown, the wearer can, as a standard action, project a cone of fear (Will DC 20 partial) or make a melee touch attack to use inflict critical wounds (Will DC 20 half).
