You call on your connection with spirits and the spiritual to exude a spectral scent similar to that exuded by ghostly Undead. Until the spell ends, each Undead within 30 feet of you prefers other targets to you, unless you attacked that Undead in the last minute. In addition, if you have taken no aggressive action against an Undead within the last minute, you have advantage on Charisma checks made to influence Undead within 30 feet of you.
