As two actions, you whisper a damning secret to a creature that you can touch or see within 10 meters. Only the creature can hear the whisper. The creature must make a Will saving throw. If the creature doesn’t share a language with you or if it can’t hear you, the spell has no effect on it.
On a failure, it is charmed by you for the duration. The creature interprets the whispers as a description of its most mortifying secret. You gain no knowledge of this secret, but the target is convinced you know it. The charmed creature obeys your commands for fear that you will reveal its secret. It won’t risk its life for you or fight for you, unless it was already inclined to do so. It grants you favors and gifts it would offer to a close friend.
The spell ends if you or your allies attack, damage, or attempt to negatively effect the charmed creature in any way.
When the effect ends, the creature has no understanding of why it held you in such fear.
