Description

This pewter tankard gleams brighter than the lanternlight around it, its surface etched with crossed quills that seem to quiver when raised in a toast. Guild rumor claims it was commissioned by an arbiter who grew tired of lies drowning out justice — though many insist the tankard has ruined more friendships than it has mended disputes.

“Careful what you confess ’round that pewter cup…”
Trollskull Alley gossip

Rules

Magic Effect

  • Activation: Raise a toast (bonus action). A faint ripple of silver light rolls through the air.
  • Effect: For 1 minute, each creature that hears the toast must succeed on a DC 13 Charisma save or become unable to speak deliberate falsehoods. They may avoid answering, speak half-truths, or mislead by omission — but they cannot knowingly lie.
  • Awareness: Affected creatures know they are constrained, often leading to panic, anger, or sudden confessions.
  • Immunity: On a success, a creature is unaffected and becomes immune to the tankard’s magic for 24 hours.

Limitations

  • Charges: 1 use per dawn; the tankard regains its magic at dawn.
  • Range: Any creature that can hear the toast.
  • Counterplay: Silence, loud ambience, or magical noise can blunt its impact.

Designer Note

This item nudges stalled roleplay forward without forcing confessions. Let players feel the tension: they can deflect or stay silent — they just can’t lie.

Hooks & Usage

  • Guild Arbitration: An artisan feud ends with “the honest tankard” — and an unexpected confession that changes everything.
  • Frewn’s Brews Trap: A rival tavern owner baits the party into a manipulated honesty toast while spies listen from the next table.
  • Backfire Drama: A PC blurts out a secret they never meant to share. Instant character development.
  • The Tankard Thief: A thief mistakes it for a relic that reveals true names; their belief causes a citywide misunderstanding.

“Justice is what remains when lies are poured out.”

Old Waterdhavian proverb

DM Notes

  • Scaling: Adjust the save DC by table conditions: a hushed courtroom (+2), a rowdy tavern (−2).
  • Consequences: Priests, paladins, and nobles may consider magically induced honesty unethical or illegal — roleplay the backlash.
  • Foreshadow: Seed rumors and wall-notices: “Confess at the Quills — tankards tell no lies.”
