Interdiction
This powerful spell affects all enemies of the spellcasting priest who enter the area of effect. The spell inflicts a -2 penalty on saving throws, a -1 penalty to armor class, and a -1 penalty to attack and damage rolls. Creatures friendly to the cleric gain corresponding bonuses - +2 to saving throws, +1 to attack and damage rolls, and a bonus of 1 to AC. Additional effects are possible, depending on the Power granting the spell; effects must correspond (or at least not conflict) with the spheres the priest normally uses. Multiple effects are possible.
The variation for the Wards Sphere requires that each hostile creature entering the area of effect make a saving throw vs. spells with a -4 penalty or suffer 4d6 points of damage. An affected creature must then flee the area; it is unable to return. The creature must make a second saving throw vs. spell with a -4 penalty as it leaves the area or be blinded until magically cured.
The variation for the Law Sphere requires that a hostile creature make a saving throw every time it wishes to change an action. Thus, if a creature wishes to stop running and draw a weapon, a successful save is needed or the creature continues to run. Actions that cannot be continued (e.g., firing an arrow if the archer has no more arrows) are repeated as empty automatisms. In addition, creatures hostile to the priest automatically fail saving throws against Enchantment/Charm spells cast by the priest.
The variation for the Chaos Sphere requires that hostile creatures make saving throws vs. spells at -4 or be affected by Confusion (as per the spell). Affected creatures have a 5% chance per round of suddenly being attacked by a Phantasmal Killer.
All creatures who enter the area of effect are subject to the effects of the spell. All effects except blindness cease 3 rounds after an affected creature leaves the area. Creatures reentering the area of effect must make new saving throws.
