So the new followers come Legion are called Champions. And although I've unlocked all of them, I can't remember exactly how I unlocked them. Does someone know or can point me to a list of how to unlock them? In particular I'm interested in unlocking Sol as quickly as possible.
The other champions are:
Natalie Seline
Calia Menethil
High Priestess Ishanah
Mariella Ward
Alonsus Faol
Yalla Sagewhisper
Zabra Hexx
