Skull of Ydersius
Aura overwhelming all; CL 30th Slot none; Weight 150 lbs.
The skull of this impossibly huge viper seems to weep darkness from its ancient fangs in an endless, pestilent breath.
More than just a powerful artifact, the Skull of Ydersius is the actual skull of a deity, the vessel through which the much-diminished god of serpents perceives and influences existence. Ydersius's clerics still receive spells from their prayers, granted by the skull regardless of its location or ownership. There is no way a mortal can block this effect. Possession of the skull grants several abilities.
