Tomb Entrance: Start walking the wooden bridge, but take the wooden plank to the left of it instead of following it all the way up to the next area. Follow this to another gap, jump over, and latch on to the ice wall to climb up to the ledge above it. Take the ramp on the far left and jump over a gap into a tunnel. Following the main path of this cave, you'll take Lara and swim under a barrier into the next room. Lara winds up falling into a cave below when the ice breaks off. Upon reaching this location, players attempt to jump over to an ice wall to latch on. Precursors: The first tomb's entrance is relatively easy to find as you pass it while moving through the Glacial Cavern area during Best Laid Plains.
Reward: Ancient Abilities. Quickly shoot up to 2 successive arrows without the delay of redrawing from the quiver.
