As you move forward the stairs crumble beneath you, so either go quickly or trigger the collapse before jumping across.

At the top, various enemies, including skeletons and exploding mummies, jump up out of the chasm ahead. Destroy them and gather supplies and gems from the urns and beneath the cracked floor.

Jump onto the nearest of the rotating gears, taking care to avoid the flame jets as much as possible. Again, equipping items that confer fire resistance helps immensely. As soon as you touch down on the first gear, an archer appears on the column to the lower right. Shoot it down...

...and then ride the gear around to the left. Another archer materializes on the next column. Take it out as well. These two may drop ammo, which you can retrieve if you need it.

The flame jets here do not spin. To get past them without taking damage, hang from the edge and ride along beneath the flame as the gear turns. Once you've cleared the flame, pull up...

Hop back down onto the gear, hang from the edge once more, ride around beneath the other flame jet, and then pull up.

Jump back onto the next gear downscreen. Move carefully along its right side and jump onto the gear to the lower right.

A third archer appears on the column to the right. Shoot it, collect any goodies it drops, and then jump back to the gear with the single flame jet.
