This mystery can be found near the centre of Hamtunscire, just west of the city of Wincestre.
Speak with the Monk and Defeat Faith
When you arrive at the location of the mystery, you’ll find a few Christians engaged in an act of prayer. As you draw near, they will beckon for you to join them. Speak with the monk to begin the mystery. The dialogue here will inevitably lead to a conflict with a large and powerful woman referred to as “Faith”. You’ll need to defeat Faith, who only uses her fists (and occasionally throws a pot) during the fight.
If you choose to use your weapons, this will be an easy fight, especially if you chose a weapon with a long reach. To make it more interesting, you could limit yourself to fighting with your fists only. In this case, you’ll need to pay close attention to Faith as she spams red rune aura attacks, which you’ll need to dodge, roll, or run out of the way from. Faith is relentless in her attack so you won’t have much time to breathe. The Brush with Death skill (Way of the Raven) will prove very useful, allowing you to slow time whenever you dodge an attack from Faith, giving you enough time to retaliate with a series of light or heavy attacks.
When Faith is dead, the mystery will complete.
