When the priest casts a Sanctuary spell, it causes all of <PRO_HISHER> opponents to ignore <PRO_HISHER> existence as if <PRO_HESHE> were invisible. While protected by this spell, the subject cannot take direct offensive action without breaking the spell, but can use non-attack spells or otherwise act in any way that does not violate the prohibition against offensive action. This allows a warded priest to heal wounds, for example, or to bless <PRO_HIMHER>self. The priest cannot cast spells on other creatures without ending the spell.
