how do new scores affect hp, after polymorphing?

The rule for Con loss - damage or drain - is that the hit point score cannot drop below 1 per hit die... not that an individual hit die cannot drop below 1.

Thanks, Hypersmurf. That is quite clear now.

There are solid, practical reasons for this method.

If I am a DM and I pull out a vanilla 8 HD monster and use average stats, it will have 36 HP (assuming a +0 Con mod). If this monster suffers -2 Con, it immediately loses exactly 8 HPs even though one could logically argue it "should" lose 8 or 7 or 6 depending on the actual hit die rolls. Since the MM does not supply hit die rolls, the DM does not want to worry over this detail. Nor would there be any particular joy in carefully tracking each hit die for a PC in the middle of combat.

No. The general rule is stated on page 9 of the PHB: that a Constitution penalty can never drop the results of any hit die below 1.

That's not what's written there. It says, that during level up, when you roll your hit die, you always gain at least 1 hit point, nothing else.

You can't just take half a sentence and say, there's the rule!

It applies to the actual roll of the hit die, a roll, that only happens during level up to increase the hit point total. It's also quite clearly written, what that rule means in the part you omit so generously: "..., that is, a character always gains at least 1 hit point each time he or she advances a level."

I don't have to extrapolate the restatement of the general rule as reagrds a specific case to another specific case - there's still nothing in the rules that says that Constitution reduction can ever drop hit points below 1 for a hit die.

Not specifically written, because basic mathematics allow for negative numbers; that's also not necessary. If the score could not drop below zero, they would have to say so, but they don't, only for three distinct cases (determination of the new hit point total during level up, Con damage and drain)!

Page 7 of the PHB.

That says, what I totally agree with as written above, that Con modifier is added to each hit die roll. Never said that this is not the case.

Right. So the modifier from Constitution is a named bonus, and follows the rules of a bonus - including that it does not stack with like bonuses and that it applies as a single monolithic number, rather than as a series of discrete differentiable units.

Yes.

So Constitution is a named bonus or penalty applied seperately to each hit die and it can't lower any individual result below 1.

No. You - again - drop half the sentence and just use part of it.

If a character's Constitution score changes enough to alter his or her Constitution modifier, the character's hit points increase or decrease accordingly.

So the modifier is recalculated every single time the modifier changes.

Actually, I understand accordingly different. Accordingly is in context to the alteration mentioned, so the hit point score is changed according to the difference in Constitution.

You are way over thinking this. You just have a series of hit die rolls from 1st level on to 20th and each of them is modified by your current Constitution. Nothing fancy - no special rules take over if you have a reduced Constitution when you go up in level, and you don't have some kind of whacky "partial Constitution modifier" ever.

That's right so far.

Now going further, you have a hit point total, which is a single number, not a series of numbers added together, altho - over the course of time - it's derived like one, because changes are applied in the way mentioned above and not by recalculating the total.

Whenever you go up a level, you add hit points to this total (as quoted above). Whenever your Constitution changes, you also change this total accordingly (as quoted above and in the glossary in the back of the PHB (also quoted above)). That's also why you add hit points multiplied with level, when your Con changes (like with Rage).

Dunno, but I think my view of the rules is heavily supported by quotes, which you say are merely mathematical shortcuts, as they don't fit into your view, like the part on page 9, which limits the application of your "general rule" to a very specific case.

Correct. This information (indivdual hit die rolls) is not memorized, it's conglomerated into the hit point total.

So if my 10th-level character suffers 2 points of Constitution damage, I don't need to remember what he rolled for hit points at level 2 through 10? Wow, what a relief. :rolleyes:

Thanee and Hyp make great arguments. It's too cumbersome to do it any other way.
 

Too cumbersome?

No. Too cumbersome is when you have to keep track of more than one complete Constitution value simultaneously as Thanee suggested.

Keeping a list of all your hit die rolls just makes sense from a book keeping situation. How many times has someone in your group forgotten whether they even rolled a hit die for their last level? Or done their math wrong, and lost track of how many hit points they should have?

If you play with a large number of people, you'll see this kind of crap fairly often - almost as often as people forgetting to add XP at the end of an evening and then trying to figure out how much they should have.

Keeping a list of each hit die in order makes sense, and it is implied by the rules. You should do it, and the rules support it.

As for generic monsters - they actually get "generic" results for each hit die. They don't have an aggregate of various hit points - they actually "roll" 4.5 hit points per die. So it's not a problem.

Whether I agree or not with Thanee is irrelevent:

Bravo, Thanee, for not responding to the personal slanders of others, and using measured, rule-based discussion to prove you point. Bravo!

Well, you have to remember the old Constitution score anyways, when polymorphing, otherwise you wouldn't know what happens, once the spell ends! ;)

And there is nothing cumbersome at all. You just apply the modifcations and that's it. This is how they do it in every example in the book, which I have seen, too (guess I have quoted enough of those already).

You still haven't come up with a plausible, rules based answer for what happens in your system when you have a Constitution of 12 and Polymorph into a creature with a Constitution of 19.

And then take 1 point of Constitution damage.

Your constitution has not changed enough to change the modifier. By the rules, you don't modify hit points at this point.

So what happens under your system? Your Constitution modifier is still 4, but with your old Constitution which you no longer have, it "would have" been reduced from +1 to +0. The rules do not support changing hit points at this time - and since your system says that we must it is both too cumbersome and against the rules as written.

Not to mention that the people who actually wrote the rules don't agree with you.
