Flooded Archives - Greek Fire Puzzle Southwest Corner

Move past the rope-wrapped post toward the upper end of the pool.

Use a rope arrow to open the hatch, releasing a Greek fire vessel, just like you did on the other side of this area.

The vessel floats downstream but is stopped by a heap of debris.

Shoot the vessel to blow it up, burning off the debris and clearing the way.

Return to the hatch and release another jar of Greek fire.

If you let it float downstream...

...it will soon run into the burning debris leftover from your previous explosion.

This will destroy the vessel in a spectacular but unhelpful way.

Instead, after releasing a vessel from the chute...

...run back to the rope-wrapped post and wait for the vessel to float past. Then shoot it with a rope arrow to anchor it to the post.

As the vessel floats downstream, the rope causes it to tack to the left so it misses the fire. Now cut the rope...

...and let the vessel continue downstream.

Move to the wooden ledge overlooking the pool, but don't ride the zip line. Instead, as the Greek fire vessel floats toward the statue, jump across the stream and pick up a pile of Byzantine coins sitting on the stone ledge.

Only after you have the coins and anything else you need in this area, shoot the Greek fire vessel to trigger a cutscene.
