false gem you carry before Constantine has finished his enchanting. Watch
Constantine. When he starts walking to a pedestal that is turned away from
you, you'll have a minute to get to The Eye. Walk carefully because the
sound here will carry. You may want to use a few moss arrows to help you
move more silently. Once at The Eye, switch it with the false gem, and
carefully get back to cover. Hide in the shadows so that Constantine can't
see you, and wait.The Trickster's Demise All you need to do is wait. When
Constantine finishes his spell, he'll realize that he has been tricked, the
false gem will lash out and kill him, and the mission will end.
