Great Good (3.5e Equipment)
From D&D Wiki
Great Good: A great good weapon functions as a holy weapon, but it also produces a burst of good energy on a critical hit. On a successful critical hit, the target is affected by the dispelling effect of dispel evil, except that 1d3 spells are dispelled rather than one.
