Crimson Desert: Sanctum of Penitence Guide

Starting the Quest

Meeting the Witch of Wisdom is part of the “Black and White” Main Quest storyline, where you have to find the Witch of Wisdom. She then has the request to cleanse four sanctums:
-> Sanctum of Absolution
-> Sanctum of Temperance
-> Sanctum of Penitence
-> Sanctum of Benediction

The Witch of Wisdom is part of the Hernand: Witches Quest Section.

Quest description:
“They say witches live in hidden locations throughout Pywel.”

Liberate the Sanctum of Penitence

Description
“A place said to be imbued with spiritual power. It is known to have been created by someone in the past to restore the world and its providence, yet its power is so great that Antumbra revere it as sacred ground. The Seventh Edict declares: Should the thought of abandoning your faith arise, be penitent and purify your heart.”

The Sanctum of Penitence is southeast of Howling Hill and the Goldleaf Guildhouse. Defeat the Antumbra Order and liberate the place first.

Cleanse the Sanctum of Penitence

After the liberation, the Sanctum of Penitence has to be cleansed. The Sanctum, four pillars, and the only pillar-part you need to restore them are visible on the minimap with specific symbols. So keep your eye on it while exploring.

Enter the building and look for the top part of one of the pillars. It has a cubic shape and is in one of the top-floor rooms without a ceiling. Use Axiom Force on it and store it in the Kuku Pot.

Return to the Sanctum of Penitence and discard the Sanctum of Penitence Fusion Reactor Core from your Kuku Pot inventory. Pick it up with Axiom Force and put it on top of the damaged pillar. Then, climb the pillar and use a jump-Force Palm to lock the part in. This will cleanse the Sanctum of Penitence.
