Holy aura

Holy aura was an abjuration spell that granted protection against evil. It was the counterpart to the evil spell unholy aura.

Effect
A brilliant divine radiance surrounds the subjects, protecting them from attacks, granting them resistance to spells cast by evil creatures, and blinding evil creatures when they strike the subjects. This abjuration has four effects:

First, the warded creatures gain a +4 deflection bonus to AC and a +4 resistance bonus to saves. Unlike protection from evil, this benefit applies against all attacks, not just against attacks by evil creatures.

Second, the warded creatures gain SR 25 against evil spells and spells cast by evil creatures.

Third, the abjuration blocks possession and mental influence, just as protection from evil does.

Finally, if an evil creature succeeds at a melee attack against a warded creature, the offending attacker is blinded (Fortitude save negates, as blindness/deafness, but against holy aura's save DC).

Focus
A tiny reliquary containing some sacred relic, such as a scrap of cloth from a saint's robe or a piece of parchment from a holy text. The reliquary costs at least 500 gp.
