Greetings CARLAfkv,
Creating "new" Aoidos reinc requires "Aoidos Spark" and this is spent the first time you create Aoido reinc. Unfortunately, it is impossible to get one more Aoidoi Spark in the game.
But;
- You can transform another reincarnation into Aoidos through the "Hall of Change"
- Coremorpher will also allow to change race to Aoidos
