The Nod from Nanny

You nod at a target and they feel emboldened in their decisions as if mom would be proud. The sensation is joyful with a knowledge of being right.

While engaged in combat the target must succeed on a wisdom check (DC16) to gain advantage on their next D20 roll. The DC decreases as you level: 14 at 5th, 12 at 11th, 10 at 17th.
