Sphere of security protects the priest who casts the spell and his companions within the area of effect. Enemy creatures within the area are unaffected.
The sphere grants affected creatures a +2 bonus to armor class, a +2 bonus to all saving throws vs. magic, and 50% magic resistance. Casting this portion of the spell requires 1 round.
In addition, the priest can specify as many as four additional specific protection effects from the List of Protection Scrolls in Appendix 3 of the DMG. Each additional protection lengthens casting time by 1 round. The priest may create one effect per 5 levels of his experience, to a maximum of four effects.
