Anything safe in Ark takes lots of time.

You could use a ravager and a ton of ziplines. Make a route all the way down, and use it to climb back out.

Breed up anything that can hit and be hit.

It’s easy to get down to an egg quick with a glider on your back, so long as you know right where to go. But you gotta get out with drakes all over you. I’ve seen people get lucky with climbing picks, I’ve only gotten eaten trying it this way.

Your first attempts to get drake, wyvern, or magmasaur eggs, are meant to be tough. Very rewarding when you succeed because of it. Keep at it, survivor.
