Hitroll, Damroll and Saving Throws are some of the raw mechanics
of Dark Pawns.  A few brief definitions:

Hitroll: Your chance to hit someone during combat, as applied to
         their [AC](/help/info/ac-armor/).  Plus hitroll is good, minus hitroll is bad.

Damroll: The amount of damage you do in addition to the average
         per round damage of your weapon. Again, plus is more 
         damage, minus, less damage.

Saving Throws: How well your character is protected against 
               certain specialized attacks, like spells, breath
               weapons, and petrification. Minus saving throws
               indicates better protection against a certain 
               type.
