Constitution

From dodWiki

Constitution (CON in your 'score') represents your character's physical stamina. Among other things, it affects:

• the number of hitpoints a character gains each time it levels
• the number of hitpoints recovered or regenerated at each tick if resting or sleeping
• the number of additional moves a character receives at level
• improvement or worsening of a character's mental state, thus affecting general endurance

Constitution is the prime attribute of the Psioniscists
