Amulet vs Undead

This prized charm is a specially blessed symbol that enables the wearer to turn undead more effectively. The amulet appears ordinary, but glows brightly when presented strongly (i.e., as if it were a holy symbol) in the presence of undead.  When Turn Undead is used, Undead have disadvantage on the Saving Throw.

Notes: Bonus: Spell Save DC, cleric or paladin, Necklace, Bane
