Con Change & Overall HP - Clear Statement?

[Sigurd]

My temptation has always been to treat HP as an incremental thing that you accumulate like skill points - close reading of the rules is unclear though.

Anyone with a clear source?

Joe's the 6th level fighter gets a permanent increase to con such that his hp bonus increases by +1. Does he get 1 more hp immediately and at his future levels or 6hp immediately?

If his con drops so that he looses a bonus hp, does he lose 1hp for every character level immediately?

I'm looking for a clear reference.

PHB page 9. Constitution. Below the bullet points:
"If a character's Constitution score changes enough to alter his or her Constitution modifier, the character's hit points also increase or decrease accordingly."

I read that. I just wish it said "the character's _total_ hit points also increase or decrease accordingly"

 

[irdeggman]

PHB pg 10 under changing ability scores.

When an ability score changes, all attributes associated with that score change accordingly.

It goes on to say that Int mod with regard to skill points is not retroactive though.

PHB pg 146 under Increases in Constitution Score and Curent Hit Points.

An increase in a character's Constitution score, even a temporary one, can give her more hit points (an effective hit point increase(, but these are not temporary hit points.

DMG, page 290:

If a character’s Constitution score drops, then he loses 1 hit
point per Hit Die for every point by which his Constitution modifier
drops. For example, at 7th level, Tordek is hit by poison that
causes his Constitution to drop from 16 to 13. His Constitution
modifier falls from +3 to +1, so he loses 14 hit points (2 per level).
A minute later, the poison deals another 8 points of Constitution
damage, dropping his score to 5 and his modifier to –3. He loses
another 28 hit points—for a total of 42 hit points lost because of​

an overall 6-point drop in his Constitution modifier.
