Gem Puzzle (Demon Cult Mission)
During the passage of GreedFall, you will receive the mission "Demonic Cult", in which you need to study rumors about an evil cult rooted in one of the villages on the island. You will come to the place where you need to follow one of the villagers to find out what he is up to. As you walk through the forest, you come across an ancient tree with a circle of stones, and the only way to go further is to light the candles in the correct order.
Before you start, walk around the circle of stones and inspect each one so you know what each one means. Once this happens, light the candles in the following order:
As soon as you do this, a passage to the cave will open under the tree and you can continue the quest.
Drum Puzzle (Mission "Face to Face with the Demon")
