Path to Ancestry: Details & FAQ - Changing Race after Ascension
What do I need to know if I want to change my race (using a Metamorphosis Stone)?
It is possible to change race, but not:
- if units or layers are on cooldown
- if units are being recruited
As a result of changing race:
- Your current Ascension will change to match the new race automatically.
- Your units will disappear, but you receive 70% of the Blood Essence you invested.
- Your Ancestral Ruins progress remains unchanged.
