This spell was created by Celestarion to be his ultimate form of protection. Whether it is or is not is left up to the individual wizard, but nonetheless it is a powerful spell.
When cast, a sphere of swirling black and white light appears to surround the wizard and all those close to him. The barrier has all of the following effects:
	It prevents any spells going through it. What happens is that the spell energy is drawn into the top of the sphere.
	The lighting effects of the sphere prevent anyone from seeing through it, although those on the inside can see out. This results in a -4 to-hit penalty.
	All magic within the sphere is unaffected. Spells cannot be cast out of it, but can be cast within it.
	No living being can pass through the sphere unless a saving throw versus spell is made with a -6 penalty. If they fail their saving throw, they are simply unable to pass through.
	No magic items of any sort can pass through.
	Normal physical objects can pass through, as can psionic attacks.
	If the barrier is not hit by a spell or a magic item or any psionic discipline, then the barrier needs energy. It draws 2d4 of the wizard's hit points for every round that it isn't hit. Should the wizard's hit points go below 10% of their maximum, he starts to lose one level per round. The spell continues for as long as his initial level in rounds. When he has lost half his levels, then he starts to lose 1 Intelligence point per round until the spell ends.
	The wizard cannot voluntarily end the spell.
Hit point and level losses are temporary and return at the rate of one per turn each, but Intelligence losses are permanent. These effects can be avoided if the wizard himself casts a spell at the barrier. He cannot dispel it when he wishes, however.
The material components of this spell are one star sapphire, and one black star opal of at least 20,000 gp value each. Both are lost in the casting.
