Can anybody tell me what does it do?
I have no idea what is that item for. In case you don't remember which one is it, it is located in the entrance hall of the sanctum sanctorum, on a table to the left side of the house.
Thx in advance :carnage:
Yes, you can't talk to the Ancient One without it. The gem is placed near the top of the mirror the first time you interact with it.
That explains it :)
lol I always picked the gem without wondering why would I need it
Same here! It took several times before I realized what was going on and why.
