After you've lined up, crouch down, place a bomb, walk to the other side of it, and whip it once to the left.

It's hard to explain but there is a gif below showing the whole technique so watch that for this part. To do this easily, simple whip to the right as your jump into the wall pieces and then fall straight down. You need to perfectly align your back to that wall and fall down on the right side while facing the right. From here, you can see the exit from the Ankh and to the left of that there are a few blocks sticking out of the ceiling. Simply go to the top right of the level and climb the ladder to the top.

You'll need 3 bombs and a rope if you don't have vlads, jetpack, spring shoes, or climbing gloves. This is the absolute fastest way to get the Ankh and requires little to no skill. The first one I'm going to go over is called the Olmec skip. I will go through each one and you can decide which one works best for your needs for not only this run, but all runs in the future, as the Ankh is a very important item for the late game achievements. While this may seem simple, there are actually many different approaches to this which all require different timings and levels of patience. Getting the Ankh requires you to fully defeat Olmec on 3-1 meaning having him crash all the way to the bottom of the level and drowning in lava while you stand on his head and walk through the entrance to the backlayer which leads to the Ankh which is at the top.
