You know, one might suggest that this is supernatural healing.
And one might be wrong, as it's spelled out to be sheer force of will propelling Inigo up and back into the fight. There's no cleric chanting over him, nor spirits healing him. It's his hand in his gut stopping the blood, and his will to get his vengeance that restores him to effectiveness.
And, if this is the sort of "second wind" going on several times in each battle then it borders on the absurd.
It only happens once. And Second Wind in 4e is once per encounter, too, so I don't see the point in bringing that up.
If we were to assume that John from Die Hard fought day after day on his second winds -- as 4e characters can potentially do, no matter how savage the beating each day -- the Die Hard franchise would be far across the borders of absurd and into the regions of the ludicrous.
Die Hard IS pretty ludicrous, just like most American action movies are.
Sure, this is what they say, but in actual play:
So, let's just ignore what they say because... it doesn't fit the argument? What the books say is the utmost importance, because the set the standard for the game. If the book says they represent that, then they represent that, because the book would be a higher authority on the subject than someone else.
1e: Fighter with 10 hp takes 8 hp damage. He is now down to 2 hp. The player has a pretty good idea of exactly what sort of condition his character is in, and the DM has no difficulty describing the blow causing that damage within the context of the 1e paradigm.
Yeah, his condition is "unaffected by wounds at all," since being wounded doesn't have any impact on your condition until you're unconscious or dead. Being that hit point loss doesn't result in any change in fighting condition until the point of no return, the 1e fighter losing 8 hp is just the same as the 4e fighter losing hp: his skill turned a potentially lethal blow into a lesser one.
And here's a counter...
1e: Fighter with 85 hp takes 10 hp damage. He is now down to 75 hp. The cleric casts cure light wounds on him, despite the hp loss not actually representing wounds by the definition in the book, and the wound that doesn't actually exist gets healed. So, the in-game story runs into a serious conflict where one system states that the character is not actually physically wounded, while the healing effect is a magical wound closer.
So, if a Second Wind is problem with the "is it really a wound" question, then 1e has that same problem with it's "skill, luck, or magical factors" explanation for hit points, since you can't cure wounds that don't exist, right?
Neither the player nor the DM knows if it is a wound at the time it is taken because, within context of the in-world story, if the fighter recieves magical healing later it was a wound, but a second wind means that it was not.
Not true. Since hit points represent things like skill, luck, resolve, and the like, you could easily describe it as a wound, and a Second Wind represents ignoring the wound and pushing yourself beyond your normal limits... or it could represent you plugging the wound... or the classic Bruce Lee wiping the blood from his wound, licking it, then coming back in for more.
In the 1e paradigm, the in-world story is never required to change based on later PC or NPC actions. The in-world story unfolds as the story is played at the game table.
Not according to the discrepancy between the "skill, luck, or magical factors" explanation for hit points, and the fact that magical healing is described as closing and mending wounds. How can a spell to close and mend your wounds be effective when the hit point less doesn't represent wounds?
