Constitution

Players Handbook (page 12)

Constitution is a term which encompasses the character’s physique, fitness, health, and resistance. Since constitution affects the character‘s hit dice and chances of surviving such great system shocks as being changed by magic spell or resurrected from the dead, it is of considerable importance to all classes. Constitution scores of above a certain number are necessary for becoming certain sub-classes of characters. Effects of constitution are given on the table below.
It is of utmost importance to understand that a character’s initial constitution score is also the maximum number of times the character can be raised from the dead/resurrected, and that each such revivification reduces the character’s constitution score by 1. Although a character’s constitution can be restored to its former score, or even raised above this number, by magical means, this in no way alters the initial score limitation, nor does such magical change in constitution restore to the character additional chances for revivification. Thus, if a character has an initial constitution of 15, he or she can never be brought back to life by a raise dead or resurrection spell more often than 15 times. Note that a rod of resurrection is considered the same as a spell of the same sort. The 16th death is final and irrevocable without use of some other magical means such as a wish.
