As lesser restoration, except the spell also dispels negative energy 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 1 day per caster level.
Restoration cures all temporary ability damage, and it restores all points permanently drained from a single ability score (caster’s choice if more than one is drained).
Restoration does not restore levels or Constitution points lost due to death.
