Oh, dear, hope you can reload: There was a book in the Cursed Abbey warning you to not disturb the Dead = you did it - so no sacrifice, except by reloading <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Kiya
After reloading: Keep all 3 items in your inventory and just stand in the right circle. The left one will then contain your end item after you told the statue your choice.
