Karma-Heavy Cavern (Chinese: 散发「业障」气息的洞天 "Heavenly Cavern that emits the breath of Karmic Sin") is a story domain for Alatus Chapter, Act I quest "The Purging of Evil". After it is completed it can not be re-entered.
Due to the nature of this domain, Xiao's Elemental Burst is permanently active, constantly draining a percentage of his health (down to 1 HP). Attacking enemies will regenerate health.
There are 3 chests that can be found in this domain:
- Exquisite Chest ×2 (unlocked after completing the first and second platforms, respectively)
- Precious Chest ×1 (after completing the domain)
- Character: Xiao
Unlike other Story Domains, your party is restricted to the trial character version of Xiao alone; even though you will be taken to the party selection screen before entering, your characters will not be usable.
