Divine interdiction interferes with a cleric's connection to his or her divine source of power, resulting in a temporary loss of the ability to turn or rebuke undead. Paladins, blackguards, and other classes capable of rebuking, turning, or otherwise commanding the undead can also suffer a temporary loss of this ability through divine interdiction.

The effects of divine interdiction include other turning-like abilities -- for example, it also applies to any divine ability to command, rebuke, or turn elementals, outsiders, lycanthropes, or other types of creatures.

Divine interdiction temporarily negates any extraordinary, spell-like, or supernatural granted powers due to access to a spell domain. Special powers from domain access (such as increased caster levels, death touch, or smiting, among others) are lost for the duration of the spell. Domain benefits that result in skill proficiency (such as Trickery’s allowance of Bluff, Disguise, and Hide as class skills) are unaffected, as the skill is already learned and committed to memory, not powered daily by divine force.

This spell creates a beam of invisible disruptive energy that streaks out from the caster’s pointed finger to strike the target(s) automatically. If a target has some way to avoid such a beam, that target benefits only from his or her size modifier, Dexterity modifier, and deflection bonus (if any); armor bonuses, shield bonuses, or natural armor bonus do not apply.

The spell can be cast on a point in space, but the effect is stationary unless cast on a mobile object. The spell can be centered on a creature, and the effect then radiates from the creature and moves as it moves. An unwilling creature can attempt a Will save to negate the spell and can use SR, if any. Should the save fail, the target’s turning abilities are immediately negated for the spell’s duration.

While under the influence of divine interdiction, the target is treated as though he or she has no divine abilites, including the ability to turn, rebuke, or command undead. Note that the spell does not prevent positive or negative energy from affecting undead within the area (it merely becomes a barrier to activating such powers).
