At the beginning of the act 3, Asmodheus gave you a doll, this doll is Elder Anlokar.
She has to be cured to be a real Raanaar again.
Look at your inventory, how many dolls do you have ?
Did you meet Raan ?
Did she ask you her 3 symbols (symbol of war, symbol of honor and godly symbol).
I think that you have missed something in the catacombs but i don't know what !
