Find the Serpent’s Chest

First, you’ll need to find the Serpent’s Chest and the accompanying note atVoss' Camp in Sukhothai. The chest is in thetent at the southeast cornerof the compound, to the right of the entrance area. The chest is sitting on a table on the west side of the tent, and requires three keys to open it.

Find the Three Keys

The letter from Voss next to the chest reveals that the three keys are found in three different locations you have previously visited:The Vatican, GizehandShanghai. In order to find and collect the keys, player need to have already bought the underwater breathing device at Tongdang’s Hut in Sukhothai.

Players can return to the other locations by using the Travels tab in the journal menu. It is important that players know to return to the blue revisit pointbeforetraveling to another location, as that saves the player’s progress at the location.

Jump into the water and go towards the far wall of the room, diving under to find a small room with a wood post blocking an entrance (turn on visual assistance to highlight interactive objects).

Lift the postand move it out of the way to discover a secret room. There is a round piece of stone in the center of the room, and the key can be found in a small hole in the side of it facing the front of the room.
