Duration 1 minute or until discharged
You understand that holding a secret is in itself a kind of power. Each target must attempt a Will save.
Success The target is unaffected.
Failure A rune symbolizing a secret the target is keeping (at the GM's discretion) appears floating in front of you. If that creature attempts a Strike or spell attack against you while you hold their secret, you can discharge the rune as a reaction to deal 7d6 mental damage to the creature.
Critical Failure As failure, but the target becomes convinced you know their secret and takes 1d6
persistent mental damage from worry. If the rune with the secret is discharged while the creature is still taking the persistent mental damage, the persistent mental damage immediately ends.
Heightened (+1) The mental damage increases by 2d6, and the persistent mental damage on a critical failure increases by 1.
