When this spell is cast, the life energy level of the recipient creature is raised by one. This reverses any previous life energy level drain of the creature by a force or monster. Thus, if a 10th-level character had been struck by a wight and drained to 9th level, the restoration spell would bring the character up to exactly the number of experience points necessary to restore him to 10th level once again, restoring additional Hit Dice (or hit points) and level functions accordingly. Restoration is effective only if the spell is cast within one day of the recipient's loss of life energy, per experience level of the priest casting it. A restoration spell restores the intelligence of a creature affected by afeeblemind spell. It also negates all forms of insanity. Casting this spell ages both the caster and the recipient by two years.
The reverse, energy drain, draws away one life energy level (see such undead as spectre, wight, and vampire, in the Monstrous Manual). The energy drain requires the victim to be touched. Casting this form of the spell does not age the caster.
