Specifics: This power, bestowed by the Ritual of Purification, will paralyze all undead and outsiders within 30' of the user for 3 rounds. Victims may make a Will save with a DC equal to 10 + (caster's character level/2) + (caster's INT modifier) to prevent the effects. If any target in a Web of Purity is struck by the effect of the Cleansing Nova ritual, all other victims of the same Web of Purity suffer the effects of the Cleansing Nova. Use: Selected. This feat can be used once a day.
