Re: oracle

Being a divine spontaneous caster fucks; your entire spell list is Heal if you need it, and literally anything else if you don’t. And trading a spell/day and slightly smaller repertoire for some extra durability is generally worth it in my experience.

Also Divine Access means you can pretty much pick whatever spells you want, and more as more gods come out or you and your GM make some more.

I liked the focus spells more back when battle oracles weren’t hit with the nerf bat and could literally just be the juggernaut whenever they got cursed

Not really, PF2E is its own system that is in the D20 family but no longer directly compatible with 3.X. However, since encounter balancing is easy, if you want to convert 3.X adventures to PF2E the work is pretty simple.
