Wow, thinking about it a bit, they ability to effect a manner reminiscent of someone who the viewer failed is such an Ebon Dragon charm.
IIRC you can choose to voluntarily break oaths, it just causes you ironic terrible luck? I would not want to be in a position wherein the Ebon Dragon wants me to break an oath.He can see that they're lying, sure. But that doesn't mean he can get it out of them.
