how do you get mysterious spider amulet, captured Illiana & all squares (got goblin crown), but no sign of spider amulet.
It was originally thought as hidden feature so its not described. It blocks the king quest, though, so I should have made it more obvious.
Go a second time to the Insanitarium (5 Hypnotic Archivists level) and you will find it in the chest.
Thanks, got it now, needed it to let me find the burrows.
