As lesser restoration, except the spell dispels all negative
energy levels afflicting the healed creature, restoring the
creature to the highest level it had previously achieved. This
reverses level drains by a force or creature. The drained levels
are restored only if the time since the creature lost the level
is no more than 1 week per caster level.
Greater restoration also dispels all magical effects
penalizing the characters abilities, cures all temporary
ability damage, and restores all points permanently drained from
all ability scores. It also removes all forms of insanity,
confusion, and similar mental effects. Greater restoration does
not restore levels or Constitution points lost due to death.
