The Death Domain Reaper ability says:

you learn one necromancy cantrip of your choice from any spell list. When you cast a necromancy cantrip that normally targets only one creature, the spell can instead target two creatures within range and within 5 feet of each other.

Unfortunately as far as I can tell, there are only 3 single target offensive Necromancy cantrips:

Chill Touch, Sapping Sting, Toll the Dead

Are there any class or racial abilities in the official WotC books that might allow you to use a different cantrip with the Reaper Ability?
