Notes


Golem Constructor tells you, "Hello friend. I am a third generation Golem Constructor. My sole purpose is to create useful golems for those who require them. Bring me the three Empyrean Stones combined as one and I will build you a Blank Golem. See the Sigil Keeper for a list of locations where the Empyrean used to mine and imbue these stones."
