Completing the quest to Unlock All Cleansing Beacons and Corrupted Gate Keys in Mortal Shell 2 purges dark corruption across regional pathways and opens sealed shortcuts. Purifying these light pillars cleanses toxic fog zones while key items grant passage into locked sanctums.

You need to eliminate Elite Zealots and collect key drops to progress through forbidden gates.
