Wait, in your world there are no laypeople of great faith that pray to the god of healing?"Praying to a god for healing" is casting a spell, so you'd need to have access to that spell by some means.
I mean, they can pray, certainly - but they're unlikely to have that prayer answered unless they fulfill some condition or other that gives them access to cure wounds or similar magic. That's literally what having that spell means (for a divine caster of whatever stripe): when you speak the holy words of your god or whatever, they work through you to perform a miracle. Or maybe it's your own faith that does it. Either way, it's not something any person can have happen at random, in the same way that hurling an exploding ball of fire or teleporting isn't something they can do just by wishing really hard.Wait, in your world there are no laypeople of great faith that pray to the god of healing?
Tactical Infinity: The freedom of the Player Characters to attempt any tactic to solve a problem, subject to the adjudication of the Game Master. Tactical Infinity is unique to games with a trad-style GM, and so is present in both Visible-Leaning and Invisible Leaning trad games, as well as D&D games, OSR games, and systemless games. It is not present in storygames (which replace it with directorial/authorial modes of play), and is typically irrelevant to theatrical forms.
The fighter's friend is hurt, even dying. The fighter prays to the gods to heal their friend. How is this action resolved? If it's a Religion or similar sort of check, what's the DC?
I like it as a philosophical gaming question because it reminds us that class acquisition, and the abilities granted by class, aren't generally diegetic even though we'd like think to they are.
Very few DMs are going to allow someone trained in the Arcana skill to cast magic missile with an Arcana check. But rationally, what's the difference in the fiction between someone trained in Arcana practicing to cast a spell and someone else multiclassing in wizard to gain that ability (and several others)? Most 5e DMs would allow the latter, but certainly not the former.
So I think this thread is a good indicator of just how veto-sensitive and adjudication-sensitive the concept of "Tactical Infinity" is.
