Stuff of Nightmares

Whenever you make a roll to intimidate an NPC,
you may use this ability to transform your face
into a horrifying half-man, half-platypus visage.
If you do, make the roll with advantage. If the
target fails, they become horrified, and will
attempt to flee from you. While your visage is
activated, you can only speak using sounds you
believe a platypus could make.
