This hallway has 4 pits in it. Stepping on the pressureplates will close one pit. The location of the plates are indicated on the map.
These plates are one-way plates, meaning they don't go back if you step off them, so you don't need to leave an item on them.
Stepping on each plate also opens a hidden door with enemies behind them, indicated on the map.

22 - Pit Puzzle
Throw an item on each of the pressure plates across the pits. If you don't have any projectiles, jump down in the pit, you'll find a bow and 2 arrows there, and a few mummies.
Putting weights on both plates will cause the pits to close.
When the pits are closed, stand on the left pit (south) and put an item through the grate.
Don't yet pull your items from the plates.

23 - Opened pit
This pit, once closed, but is opened by solving the Pit Puzzle
It's worth jumping down, but first, if you did not yet jump at the Pit Puzzle, do so first and flip the switch and come back here.

24 - Pressure plate puzzle
You're in a room and the door leading onward is not opened yet. Look at the other gate that has the pressure plate. This causes the door to be closed. You need to take the item off the plate again, but you cannot reach from here.
Put an item on this side of the plate as well, go back, take the item from that side, take the items from the other plates as well, and move back into this room. You can now remove the item from the plate on this side, and the door will open.

Tomb puzzle
This puzzle requires you to push all the buttons in this room to open all the doors at the end of the room. Leaving the room where you came from will close all the doors again.
You will need to use the Tombs that you used to the Tomb Keys for. The pressure plates will close the open gates and open the closed gates for all 3 gates on their respective side. I.e. triggering the northern pressure plate, it will open/close all northern pits.
Here's the big part of the puzzle: it will do the same for the pits in the large northern room at 32 as well. The western room deals with the first set, the eastern room deals with the second set. the pits open/close in the same way relative to the wind direction, not the area you're facing. I.e. the doorways are not the starting point for the main room.
Now, you need to make it so that the buttons in room 32 can all be reachable, AND you need to be able to walk across.
See 34 - Western Tomb Room and 35 - Eastern Tomb Room for the solution.

33 - Shuriken (1)

34 - Western Tomb Room
Put items on the northern, eastern and southern pressure plates. (Not on the western one).

35 - Eastern Tomb Room
Put items on the northern, eastern and southern pressure plates. (Not on the western one). This means you actually do need to put an item on the western one because otherwise you'll fall down. Put it on the western one, then put it on all the other plates, leave the room, and pick up the item on the western plate.

Tomb of the Guardian

First, in order to reach a secret room downstairs, put an item on the closed pit.

In order to cross, put an item on the pressure plate at the gate (western one), put the item as close to the gate as possible so you can take it again from the other side. Don't put it on the other pressure plate yet.
Step through the teleporter that appears, now take the item from the pressure plate through the gate to close the pit behind you.
Walk towards the door and face north. Throw an item across the pits so it lands on the other pressure plate and the door will open.
Go down the pits to find the secret room before you continue onwards.

43 - Ancient Claymore
A very powerful weapon with the right person to wield it! It's worth it to come all the way here. Initially, the table is shielded and you cannot break the shield. In order to lower the shield, step through the teleporter across the hall. This will teleport you in the large room across to fight several enemies. Once those enemies are killed, the shields are lowered and you can claim your prize.
