Interesting. We've been playing it that if the polymorphed character has more hit points than his usual max, then he drops to his usual max when he polymorphs back. But if his current hit point total is lower than his usual max when he changes back, it stays the same. Why does the damage remain in effect if the polymorphed form had more hit points?
Do you mean through a change in Constitution?
Assuming one allows an increase in Con in the polymorphed form to increase hit points, one must also
decrease hit points when the Con decreases at the end of the spell.
"
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."
It's why Raging can be so dangerous to a barbarian. Let's say we have an 11th level Barbarian, with a Con of 14. He's rolled 90 on his hit dice, and with his Con, he has 22 bonus hit points, for a total of 112.
During a fight, he takes 40 damage (72/112 remaining), and uses his Greater Rage ability. His Con increases by 6, which means his hit points increase accordingly - by 33. His max is now 145, and his current hit points are 105.
In the rest of the fight, he takes another hundred points of damage, leaving him on 5/145.
At this point his Greater Rage wears off, and his Con drops back to 14. His hit points decrease by 33, leaving him at -28/112, and dead.
