How to jump to the moon in PF1e

[Rynjin]

The Mythic power Seven-League Leap would allow you to do it successively, so long as you were able to bring or create a platform in midair which would allow you to run for 1 minute after "landing" somewhere in space. Notably this also removes the "you can't jump further than your move speed" restriction entirely.

More levels in Ninja also makes things easier. Remember that at level 10 with Ninja they get the ability to halve the DC of Acrobatics checks to jump by spending a Ki point. This makes the check twice as easy, and far outweighs any static +1s or 2s you get from other classes. It's kinda hard to beat a +600,000,000 bonus to Jump.
