I guess I should've specified a low magic
setting, since we're talking about the how widespread and known magic is... not the magic of your specific party
No, I meant setting as well. In tier 1, PCs are not likely to encounter anything "high magic", no powerfully magical beings, spells, or items. As they continue to adventure, the setting expands and the overall level of magic with it as the PCs travel to more remote places, encounter more rare creatures, learn more powerful spells, and discover more powerful magic.
With every encounter though? How many times do even those humanoids get in a combat where their tribal shaman is back home with the rest of the tribe?
There's a big difference between "knows healing magic exists" and "expects to run into it in every fight".
Who said anything about "with every encounter" or anything remotely like it??
You said: "
Except, even in a D&D world, many intelligent entities may have never seen a magical healer. Just because they're endemic in PC groups doesn't mean they're common."
I refuted many intelligent entities will likely have SEEN a magical healer at some point and gave examples where they might have been encountered.
So, we were never talking anything remotely like "expects to run into it in every fight", were we??? Let's keep the goalposts where you started them.
But I'm not talking about PCs here. PCs have all kinds of things present that are not, by all evidence, routine even for heavy combatants.
Neither am I. I am talking about "many intelligent entities" within the game world, which is why I mention commoners seeing a priest in a procession, a shaman in humanoid tribe, etc. where "healers" are often seen at some point BY the commoners, tribe members, etc.
I disagree its false in D&D worlds; I think you're likely overgeneralizing from limited samples and assuming those samples are typical for routine combatants.
You're free to disagree of course, but you're wrong if you look at all the published materials WotC, TSR, and probably most 3PP have created. Of course, again you shift towards combatants.
Most intelligent beings have seen magical healers, but I have no evidence they've seen them in every or even the majority of combats they've ever been in.
Ok, good, I am glad we're on the same page then.
As for any evidence about what combats they've been in, besides those with PCs which we experience first-hand often as players or DM, who can say? Frankly, they don't exist for the most part except as whatever part of the story the DM regulates them to. But given the relative cost in 5E of something as simple as a healing potion, I would imagine a number of intelligent beings have probably seen such things in a lot of battles.
Take the new gnoll warrior stat block. The gnoll as frackin' half-plate armor worth 750 gp! Chain mail would give them the same AC for 1/10th the cost--and all that other gold could easy cover the cost of a couple healing potions...
But that is besides the point. The simple fact is in most D&D games/worlds magical healers exists, most intelligent beings have seen them and know of them, so it makes sense that those intelligent creatures might take the time to double-tap or single-tap a foe to increase the chance they stay down
in case the other side has a magical healer, potion, item, or whatever that would get the foe up and back in the fight again, otherwise.
Now, in looking at the evidence we
do know about--involving PCs, how few D&D games have you played in where there was not some form of magical healing; be it potion, spell, or other item? Frankly, I can't think of a single one. I've played in D&D games without clerics or spell-healing, but in 5E not buying a simple healing potion seems crazy at least when you often have the coin for it.
