I did look around, but haven't found a definitive answer to this question...when you swap out a monk ability, to you gain JUST ONE ki ability at the appropriate level or do you have the option of using any of those listed for that level? I'm reasonably certain it's the latter, but I would like to see an official ruling. A friend of mine is making a Qinggong Monk for a campaign we'll be starting soon, and he seems confused about how the archetype works.
You pick one.
Say you have the 4th level Ki powers, and you want either Scorching Ray or Barkskin.
You can trade Slow Fall for Scorching Ray, but if you want Barkskin later you'll need to swap out High Jump or something else for it.
It would be a BEYOND amazing archetype (not that that's a bad thing) if your latter option were true.
Oops, I meant to say I was under the impression you traded out for ONE ability. Yes, I agree it would be ridiculous to get ALL of the abilities.
Also, thank you for your speedy response!
