At the top of the ice wall, you’ll find a barrel containing some resources. Move to the end of the platform and jump across to the bowsprit of the ship wedged in the cliff on the far side of the room. From the opposite end of the bowsprit, climb up to the ship itself.
You’ll find a pulley mechanism directly ahead as you pull yourself up. Interact with this to lower a large block of ice nearby. Look on the ground to the right of the this for a scroll for Document [02/04 – Greek] and to the left for a barrel containing Herbs .
Climb up the wooden block directly behind the pulley to reach a mast above. Follow this to the end and jump across to the hanging counterweight ahead. When it reaches its lowest point, drop down onto the icy ledge below.
We’ll now be able to climb the wall at the far end of the platform to the right. At the top, interact with the wheel here. This wheel will change the position of the hanging counterweight nearby and letting it go will have said counterweight slowly return to its original position, which means a timed puzzle.
We’ll want to manipulate the wheel so that the counterweight is at its lowest possible position. Once it is in place, quickly run along the mast nearby until you reach the end. Wait for the counter weight to appear by the end and jump across to it. This will smash the ice on the nearby wall, rendering it climbable. Drop down to the room below when it is safe to do so.
Jump across to the icy platform below where we just removed the ice. Climb the ice wall to the top and leap up to the handholds above (watch for a button prompt!). Shimmy to the right and pull yourself up when you are able. Scramble up the wooden wall here to reach the main section of the ship.
As soon as you reach the top, you should see a pile of Byzantine Coins you can loot. Climb the ramp and look to the right at the top to find some quivers of Arrows , the Archivist Map on a table and on the floor below it, a scroll for Document [03/04 – Greek] . At the top of the nearby stairs you’ll find an altar of sorts containing a Codex we can interact with to complete the Challenge Tomb [01/01] .
Complete any Challenge Tomb
Return down the stairs and look to the left to find a zip line. Take this to return to the main path right beside the objective marker.
