Armor of darkness

Armor of darkness is an abjuration spell exclusive to clerics with the Darkness domain. It armors the subject with shadow.

Effect
The spell envelops the warded creature in a shroud of flickering shadows. The shroud can, if the caster desires, conceal the wearer's features. In any case, it grants the subject a +3 deflection bonus to Armor Class plus an additional +1 for every four caster levels (maximum bonus +8). The subject can see through the armor as if it did not exist and is also afforded darkvision with a range of 60 feet. Finally, the subject gains a +2 saving throw bonus against any holy, good, or light spells or effects.

Undead creatures that are subjects of armor of darkness also gain +4 turn resistance.
