SRD:Holy Devastator

Holy Devastator
In the hands of any character other than a paladin, this sword performs as a +3 holy longsword. In the hands of a paladin, this weapon functions as a +7 longsword of holy power and grants a +5 sacred bonus on the wielder’s saving throws against spells with the evil descriptor or spells cast by evil characters. If the paladin wielder smites evil with the holy devastator, he or she adds twice his or her paladin level to damage (rather than his or her paladin level).
