This spell functions like
lesser restoration, except that it also dispels negative levels and restores one experience
level to a creature who has had a
level drained. The drained
level is restored only if the time since the creature lost the
level is equal to or less than one day per
caster level. A character who has a level restored by r
estoration has exactly the minimum number of experience points necessary to restore him or her to his or her previous
level.
Restoration cures all temporary ability
damage, and it restores all points permanently drained from a single ability score (your choice if more than one is drained). It also eliminates any fatigue or exhaustion suffered by the target.
