What is Constitution?
Constitution describes a character’s physical fortitude; their ability to endure pain, to take damage without falling unconscious, to resist the effects of poison, disease, and other physical maladies, to hold your breath, to travel long distances without rest, and to go without sleep for extended periods.
All characters gain additional hit points from Constitution, so most player characters have at least moderately high scores, but it’s most important for characters who fight in melee combat because those characters tend to draw more attacks and suffer more damage as a result.
Constitution can also apply in other infrequent situations, such as when suffocating and when marching long distances, but actual checks are rare.
Constitution Checks and Constitution-Based Skills
There are no skills tied to Constitution, and Constitution checks are extremely rare.
