I got all 3 parts of the statue and a crystal. I then gave all of the pieces of the statue to the head wizard like the guide says but now I cannot continue the quest without it and the wizard will not give it back... What do I do?
You should have atleast 60 def too because when you go into the tunnels there is alot of level 60+ skeletons that hit kind of hard. Unless you don't care about wasting pots forget the defence :P But only use magic on them and use range or melee on Ahrim. I prefer range because it kills him faster.
I went from level 85 to level 92 by just getting slayer from 35 - 55. Other than that... I train on lesser demons or kill blue dragons at the Watchtower quest.
