Do you have the lizard spear? And training with the warriors (strength increase one and they have a time with your face) that might be something since you need to go to them to find one of them.
Did you do a quest for Bartender called... More Potion I think? It's the one when you have to learn restrain potion recipe. When you know restrain potion recipe then you will have a first quest for Priestess, after the first one is done, the lost acolyte quest should be available.
