Path of the Deathless - More Combat on the Stairs

When you're ready to move on, go through the archway in the northeast corner where the last pair of enemies entered. Head up the steps and ready a long-range weapon like the rifle or bow.

The next 2 Deathless archers appear in the building at the top of the stairs on the left. So if you peer around the corner, you can probably shoot them without taking too much damage.

Crack open 2 salvage crates, one on the right at the bottom of the stairs...

...the other behind one of the stone pillars just ahead when Lara is facing away from the stairs.

Now head up the stairs to the platform where the archers were standing. Pick up magnesite and herbs, and loot the packs left behind when the archers vaporized. Drop down...

...and continue just to the base of the next flight of stairs to trigger the appearance of 2 more archers on the building ahead. (At this point you'll probably notice that this whole sequence is basically a retread of the Chasm Stronghold fight in the last game.)

Run back the way you came.

Then use the wall between the two flights of stairs for cover as you snipe at the two archers. It's not too difficult to get headshots from here using the rifle or bow.

You may need to change position slightly to target one, then the other.

The next brazier (3/6) for the challenge is on top of the structure where the archers were standing. Shoot the jar of Greek fire to light the signal.

Then climb up into the building where the archers were to loot their packs. There's also a salvage crate and more herbs underneath this structure.
