Weapon and Armor Proficiency: Sacred purifiers gain no proficiency with any weapons, armor, or shields.

Spells per Day/Spells Known: Beginning at 2nd level, a sacred purifier gains new spells per day (and spells known, if applicable) as if he had also gained a level in a divine spellcasting class to which he belonged before adding the prestige class level. He does not, however, gain any other benefit a character of that class would have gained (metamagic or item creation feats and so on; but see Turn Undead, below). If he had more than one divine spellcasting class before becoming a sacred purifier, he must decide to which class to add each level for the purpose of determining spells per day and spells known.

Greater Turning (Su): Once per day, a sacred purifier can perform a greater turning against an undead in place of a regular turning. The greater turning is like a normal turning, except that the undead creatures that would be turned are destroyed instead.

If the character already has this ability (such as from the Sun domain), he can use it one additional time per day.

Turn Undead (Su): Sacred purifier class levels stack with levels of all other classes that grant the ability to turn undead for the purpose of determining the character's effective cleric level for turning. See Turn or Rebuke Undead, page 159 of the Player's Handbook. For example, a 7th-level cleric/5th-level sacred purifier turns undead as a 12th-level cleric.

Sacred Strike (Su): Whenever a sacred purifier of 3rd level or higher successfully strikes an undead creature in melee, he can spend a turning attempt as a free action to deal an extra 2d6 points of damage with that attack. He can deliver such sacred strikes any number of times per round, but no more than once per attack. If the sacred purifier accidentally attempts a sacred strike against a nonundead creature, the turning attempt is lost with no effect.

Positive Energy Burst (Su): As a full-round action, a 5th-level sacred purifier can spend two turning attempts to create a positive energy burst. This energy deals 10d6 points of damage to all undead creatures within a 30-foot-radius burst centered on the sacred purifier. A successful Reflex save (DC 10 + sacred purifier's class level + sacred purifier's Cha modifier) halves this damage.
