It's a fun and useful archetype, like GolGolarion mentioned, but I personally wouldn't take it unless I'm playing a campaign where I know it'll come up a lot, and/or we're playing with Free Archetype. It's just not worth the class feat slots otherwise.

Is there anyone in the party that is Trained in Medicine? If so, let them find Healer's Tools. The Treat Wounds activity can be used by anyone at least Trained in Medicine with Healer's Tools in the inventory for out-of-combat resourceless healing once per hour per healed character, more often if you take certain skill feats, and in combat (doctor's visitation & combat medic) with some others.
Pathfinder 2e that the party is going in with full HP, balance wise, so granting your party time to heal up between fights and to Refocus is important.
I use Obsidian for prep and pen and paper for play. I absolutely adore Obsidian's versatility and have a crapton of plugins that I all use.
When worldbuilding, I like to start with a loose concept of the world, pitching that to players, and then have them ask questions about the world. I'll take those questions home and try to find satisfying answers for them until I have a barebones world, detailed enough that my players could feasibly pitch characters in it. From there, I have them all pitch 3 characters so that I find what needs to be more detailed and then I write that bit of the world.
It's all play and write as needed from there.
I use Obsidian (which is free if you use Github to sync instead of paying for their syncing service) for prep and worldbuilding, as well as initiative tracking. I bought a laptop with a touch screen specifically for running games. Other than that, I'm all analog. Drawn maps, handwritten notes, physical dice and paper character sheets have my preference.
Has /r/trees said they plan to be closed indefinitely?
