Hang on, so does that mean it's a reasonable criticism of D&D that it allows humans to generate energy from their fingertips completely unrealistically - after all, I've decided (quite reasonably) that there's no such thing as magic, and hence Magic Missile must be describing some process of the sort that physicists study?Actually, we all get to have and share our opinions about whether something is supernatural or not.
What is this difference between a PC ability and a player ability? Where does the D&D rulebook explain what it is.Now if one wants to grant a player the ability to declare their PC taunts an enemy to physically approach and attack and so long as the enemy fails a wisdom save they do so. That’s a player ability - not a PC ability - and it’s not in fiction supernatural - it’s outside fiction authorial.
There’s a tendency in more narrative games to hide narrative/authorial mechanics on the PC sheet and talk about them as if they are PC abilities, but this kind of analysis reveals the truth - while such abilities are loosely tied to something the PC does - their actual purpose is to grant the player authorial/narrative control and not to simply have the PC try to do something in the fiction.
Here's Gygax on saving throw - so pretty core to the D&D tradition, I'd say (AD&D DMG pp 80-81):
Someone once sharply criticized the concept of the saving throw as ridiculous. Could a man chained to a rock, they asked, save himself from the blast of a red dragon's breath? Why not?, I replied. If you accept fire-breathing dragons, why doubt the chance to reduce the damage sustained from such a creature's attack? Imagine that the figure, at the last moment, of course, manages to drop beneath the licking flames, or finds a crevice in which to shield his or her body, or succeeds in finding a way to be free of the fetters. Why not? The mechanics of combat or the details of the injury caused by some horrible weapon are not the key to heroic fantasy and adventure games. It is the character, how he or she becomes involved in the combat, how he or she somehow escapes - or fails to escape - the mortal threat which is important to the enjoyment and longevity of the game.
Is he describing a PC ability or a player ability?
