All creatures in the area of the spell are subject to the effects of [[SRD:Heal (Epic Spell Seed)|the ''heal'' seed]], plus the effect of an [[SRD:Atonement|''atonement'']] spell. Furthermore, any negative magical effects on the subjects, including curses, charm effects, and compulsion effects, are dispelled. Any undead creature in the area that has been undead for less than 1 month per [[SRD:Caster Level|caster level]] is instantly reverted to its pre-undead state, regaining its former alignment and personality, but losing its undead template (it regains its [[SRD:Constitution|Constitution]], [[SRD:Intelligence|Intelligence]] (if non-intelligent), and any feats, special attacks, and special qualities that it may have lost due to its template, but loses all features that it gained due to its template). An undead creature that has been undead for longer than that time is not reverted, and must make a [[SRD:Will|Will]] save (with a +15 sacred bonus if it has a soul) or be destroyed. If it makes the save, then it is freed from the control of its sire (or any spellcaster that may be commanding it through a spell or [[SRD:Turn or Rebuke Undead|clerical commanding ability]]), just as if it had been voluntarily released, and its mind is restored to its pre-undeath state; it regains its former alignment and personality (and its [[SRD:Intelligence|Intelligence]] score, if it had been a non-intelligent undead, as well as its soul if it had been soulless), and it is free to make its own decisions on how it conducts its unlife. However, it is likely to be extremely grateful to the caster of the ''purifying sanctuary'' spell for saving its soul from damnation. (Its alignment may still be threatened by the grislier details of its undeath; for example, a [[SRD:Vampire|vampire]] will still need to consume blood.) The redeemed undead is still powered by negative energy, and is affected by magical effects (especially positive and negative energy) like any other undead would be. This can make it hard, but not impossible, to get along with good-aligned characters, who may need to be very careful to avoid harming their new undead ally. In addition, the redeemed undead will remember everything that it did before being restored through ''purifying sanctuary'', as well as everything its sire made it do; if these actions were in violation of its alignment, or if it brought harm to anything or anyone that it cherishes, its redeemers should be prepared to talk it out of committing suicide. (This also applies to any undead creature restored to mortality by the spell.)
