You amplify all positive and good aspects of your soul, giving you power to resist the attacks of undead creatures. You gain a +2 sacred bonus to Armor Class and saves against undead attacks.

Because your soul shines so brightly, undead and other creatures whose bodies are supported by negative energy can see you as clearly as a campfire on a clear night, even in normal (but not magical) darkness.

For example, a vampire on the opposite side of a 500- foot diameter cavern could see you even if the cavern were unlit and even though the vampire’s darkvision only reaches 60 feet. If the vampire had attacks that reached that far, he could see and target you normally at that distance. His dominated half-orc slave could not see you unless you entered an area of light or the range of his darkvision.
