Wizard: Onomancer

Original Source: Unearthed Arcana: Cleric, Druid, and Wizard

Extract Name

2nd-level Onomancer feature
You can magically compel a creature to divulge its true name. As a Bonus Action, you target one creature you can see within 60 feet of you. The target must make a Wisdom saving throw against your spell save DC. On a successful save, you discern that this magic failed, and you can’t use this feature on the target again. On a failed save, the target is Charmed by you until the end of your next turn, and you mentally learn the charmed target’s name or the fact that the target lacks a name.

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses of it when you finish a Long Rest.
