Scepter of the Unsaid

Black horn banded in silver, with a shallow groove running most of the baton's length that stops short of either tip.

Only wizards and clerics may command it. Each charge unsays one sentence spoken aloud within the last minute: every creature that heard it forgets that it was said, and any oath, command, bargain, or spoken trigger it carried never took effect. Written words are untouched. No other magic can quicken a bearer who carries this.
