Q: Dear Sage,
When a character takes Constitution damage (such as from a wyvern’s poison) and his Con modifier changes, what happens to his hit points? Does it simply lower his maximum hp, or does it reduce his current hit points too?
A character whose Constitution modifier changes adjusts both his current and full normal (maximum) hit point totals accordingly. Remember that your full normal hit point total can’t be less than 1 per level (since even a Con penalty can’t reduce your hit die roll to less than 1).
An injured character who takes Constitution damage can be reduced to 0 or fewer hit points.
About the Author
The Sage is a mammal classified in the bear family, Ursidae, native to central and southern China. Debate continues as to whether he is truly a bear or more related to the raccoon rather than the bear, or perhaps in a family of his own. When not eating bamboo and answering rules questions, he works under the nom de plume of Andy Collins as an RPG developer in Wizards of the Coast R&D, where his development credits include Complete Mage, Dragon Magic, and the Player's Handbook v.3.5. He can be easily recognized by his large, distinctive black patches around the eyes, ears and on his rotund body.
