Unhallow Spell
D&D Description of the Unhallow Spell : unhallow makes a particular site, building, or structure an unholy site. This has three major effects.
First, the site or structure is guarded by a magic circle against good effect.
Second, all turning checks made to turn undead take a -4 penalty, and turning checks to rebuke undead gain a +4 profane bonus. Spell resistance does not apply to this effect. (This provision does not apply to the druid version of the spell.)
