can't create scrion with achievement

From what i told from people and googling you just need to get the freedom achievement to unlock scrion or is there more i need to be doing because i got that achievement just about 10-20 mins ago and then tried to make one and i still can;t find her in character selection not really sure what i need to do. thank you for your time

You need to find here in Act 3 Sceptre of God. And its Scion.

"Because of her high learning curve, she's initially unavailable to new players. The player must rescue the Scion, who can be found in the final area of Act 3, just before the fight with the final boss of this act. Killing the boss is not required to free the Scion. This can be done on Normal Difficulty (in any league) to unlock her as an accessible character."
