Amber Temple's Oath of Secrecy

If trying to reveal a secret from the Amber Temple, a creature must succeed a DC 18 Wisdom Saving Throw.

Failing to do so will result in suffering 5d10 psychic damage, then suffering a for 1 minute.

Success will break the oath, but not without consequences.

One minute after breaking the oath, a creature must roll a DC 18 Constitution Saving Throw, the creature is disintegrated as per the Disintegrate spell on a failed save, and still instantly dies on a success but its body remains intact.

If revived by any means, they are marked for death and may be ambushed by Shadowfell creatures at any time.
