This is another (relatively) easy one. We'll start in the room with the giant Razia statue, after you've recalled this horizontal bar using the Power of Memory:
Leap away from it and recall this pillar in mid-flight to grab on. From there, just take a flying leap down to that shimmering beam, remembering to zap it into existence before you get there.
You'll now be face with a fork in the road. To the right is the rest of the level, so head left.
And again, don't forget to recall the platform before you pass through it. Isn't this fun?
Hang a right after you land, and you'll find yourself in another trap-filled hallway, with lots of things you'll need to recall back into existence standing between you and the next Sarcophagus. Start with the ledge in front of you.
As you leap through the hallway, you'll not only have to time your jumps to avoid the axe blades, but time your recollections of the beams in front of you to ensure that you don't fall into the pit.
Recall the final beam, and you're just one jump away from crossing off another Sarcophagus.
After going back and following that other fork, you'll soon see a hanging banner at the end of an open hallway. Jump on that bastard and slide down.
Once you hit bottom, turn around and head left toward that waterfall.
Hey, look at what's hiding down there!
Drop down and run behind the waterfall to claim your prize. When you're done, just recall that shimmery wall with the Power of Memory to climb back out.
This is probably the most complicated Sarcophagus to get to in the entire game. When you reach Rekem's Throne Room, it's hiding in plain sight, taunting you with its inaccessibility.
Ignore it for now and walk up to the throne. See those loose bricks on the wall at the far left? You're going to need to climb them.
From here, zap that horizontal pole into existence and swing across.
Keep recalling any missing chunks of scenery directly in your way; when you get to the far end of the room, run up the wall, bounce off and recall that shimmery pole.
Once you've grabbed hold of it, turn back around and leap onto that cleft in the wall.
From the cleft, wall dash left, and remember to zap the missing chunk of wall (which holds another cleft) into existence as you do so.
From that ledge, wall-dash left again, this time recalling the missing platform before you hit it.
Dash up the next couple of ledges carved into the wall above the platform...
... and then wall-run out to your left.
As the Prince's run slows, hit jump to send him sailing onto the opposite ledge.
From here, it's just a matter of shimmying over to where the Sarcophagus is, and then dropping down to the ledge just above it.
You will have to recall that platform into existence before you try to go after the Sarcophagus, though. It may seem counterproductive, but if you just drop straight down, you'll miss the platform the Sarcophagus is on.
Instead, plod out to the middle of the platform...
... and then make it disappear. The Sarcophagus is yours!
