Characters have ten different statistics - five primary and five secondary.  
The primary statistics all start at 1 and can be increased through training, 
with each character having 25 additional points to split between them as he or
she wishes.  The secondary statistics are calculated entirely from the primary
statistics and cannot be directly manipulated or adjusted.

The primary statistics are STRENGTH, DEXTERITY, STAMINA, SIZE and WITS.

The secondary statistics are HEALTH, ATTACK, DEFENCE, DAMAGE and SPEED.

For more information about the various statistics, see the appropriate help 
files.
