The
condition of the remains is not a factor. So long as some small portion of the creature's body still exists, it can be resurrected, but the portion receiving the spell must have been part of the creature's body at the time of death. (The remains of a creature hit by a
disintegrate spell count as a small portion of its body.) The creature can have been dead no longer than 10 years per
caster level.
Upon completion of the spell, the creature is immediately restored to full
hit points, vigor, and health, with no loss of prepared spells. However, the subject loses one
level, or 2 points of Constitution if the subject was 1st
level. (If this reduction would bring its Con to 0 or lower, it can't be resurrected). This
level loss or Constitution loss cannot be repaired by any means.
You can resurrect someone killed by a death effect or someone who has been turned into an undead creature and then destroyed. You cannot resurrect someone who has died of old
age. Constructs, elementals, outsiders, and undead creatures can't be resurrected.
