Constitution-modifier changes

[nielsk]

Hi,

I have pretty much no experience with D20-based games and we just started a Pathfinder-campaign. Now one of the characters got constitution-damage and a couple of questions came up:

If the constitution-modifier changes through something (damage, drain, magical items, level-up etc.) the max HP change, correct? I.e. a level 10-character has a const-modifier of +2 and it gets reduced to -1 his max HP decrease by 30 because the change is retroactive as far as I understood it.
But does the character also gets 30 damage or do the current HP only drop if they are right now higher than the new maximum? I.e. the character has max. HP of 90 and current HP of 50 and gets now the above mentioned const-damage. The max HP are reduced to 60 but do also the current HP get reduced to 20 or do the stay at 50 since they are lower than 60 already.

Same question for an increase. I.e. the modifier increases by +1. Are only the characters max HP getting increased by 10 (L10-character) or does the character also heal 10 HP?

yes, the changes are immediate. thats why raging barbarians can kill themselves if they end a rage at low hp.

lose con, lose hp. gain con, gain hp

Don't see it as taking damage, or healing. Your current hp are adjusted 'on the fly', so you remain at the same distance from your maximum allowance all the time.

If your level 10 character, with a +2 Con modifier, has 90hp, and takes 40 damage, he's down to 50. In case of Should the Con modifier change to -1, the new max hp is 60... which you are 40 short of, sp new hp is 20.

Likewise, a friendly Bear's Endurance, raising your Con by for (and thus, your Con modifier by +2), would set your hp max from 50 to 80 hp (and, likewise, put you at 40 hp current). Just remember that those hit points will vanish once the effect ends... which may kill you quite efficiently.

Thanks for the answers. Helped a lot.
I didn't see it really as damage or healing because there might be spells or whatever that might redirect damage or whatever ;)

His maximum hit points change and the damage he has taken doesn't, as Midnight Angel described.

A good idea is never to track hit points, only track damage taken. If you do, everything can change, you still only need to check if the current damage is above current max hp.

Similarly, if you boost your con stat, your HP gain per level is retroactive. So if you had 13 con, and increase it to 14 at level 4, then your max HP becomes 4 higher than it would have been if you'd kept the con at 13.
