When you go to Beckett's go over to where Samuel is, and then glitch into the rock next to him, you should be on the lava, so once you figure out how to get up higher, just keep doing that and then you'll get up super high.
Someone Liz managed to get higher every step she took(or it seemed like every step).
If anyone wants to sky dive, PM me and we can meet and I'll show you how to do it.
