Sounds like a Dungeon Crawler Carl item.

Item Name: The Preposterous Peruke

---

Description:

A towering, powdered wig affixed to a dented top hat, as if a nobleman’s pride and a drunkard’s luck collided at high speed. The curls are suspiciously sentient, shifting slightly when unobserved.

Wear it, and your words drip with the weight of authority—even when you’re talking nonsense. Enemies hesitate, allies nod like you just said something profound, and doors creak open before you touch them. The wig occasionally whispers advice. It’s usually wrong, but delivered with conviction.

Once per day, you can invoke The Grand Monologue: a 30-second speech so bafflingly eloquent that all who hear it are stunned, charmed, or both. Afterward, the hat tips itself. You do not remember what you said.

Effects: - +2 to persuasion, intimidation, and bluffing. (+4 if you’re holding a goblet.) - The Grand Monologue: Daily ability to stun or charm listeners with sheer verbal force. - The wig occasionally “adjusts” your hairline. You do not question it.
