Weakness

The Foe is vulnerable to three specific Distractions, which are the only Distractions that can successfully fend off his attacks. These are represented by 3 Unknown Weaknesses, given when Temptation: Defiance is obtained. Each Weakness corresponds to a unique category—Environment, Quirks, or Disfavor—and can be revealed by a variety of methods.

Uncovering
There are three ways to uncover Unknown Weaknesses:
 * As a favor from a Ligeian: After catching a Ligeian in a good mood or giving her a suitable gift, you can provide her an Unknown Weakness to have her tell you what it is.
 * At a Shrine: Taking The Shattered Mysteries or The Scarred Mysteries to a Shrine will reveal a random Weakness and give you either Rage (The Lionsmith) or a Wound (The Colonel).
 * By experimentation: If you successfully defend against your Foe's attack with a Distraction matching one of the hidden Weaknesses, the Weakness will be revealed.
