I didn't know pathfinder had stamina variant rules. I haven't played any pathfinder, but the rules that I just looked up are same as starfinder but worse. I can see why it didn't catch on in pathfinder2e. It seems like easy mode, free healing after combat. And no point to the resolve in pf2e. They say it in their rules. So my first test run at it in starfinder, using the field test Soldier as an example. Hp=4, stamina=5+con. I like the idea of replacing hero points with resolve points. You get 1+your key abilitie modifier of resolve per session. You can use them to reroll a dice, To instantly recover your stamina without a rest, to lower the dieing condition by the number of resolve spent, Or to enhance your classes abilities (example as a Soldier you can spend one resolve point to make your primary target fail its check to be Suppressed). You can recover your stamina without a resolve point. You can regain one-quarter of your stamina with a 15 minutes of uninterrupted rest but after doing so can't benefit from another rest for 1 hour. That's what I got so far. The class feature is just an example I'm going to work on some more with more thought. I'll post them if people like my idea for stamina and resolve. So let me know. Thank you.
