CODA System

The CODA System is a role-playing game system designed by Decipher, Inc. for their Star Trek Role-playing Game and also used, in an altered form, in their Lord of the Rings Roleplaying Game. It uses six-sided dice, and a standard set of character statistics, as well as skills and edges (which are similar in function to the d20 System 'Feats'). Characters belong to a class, and can adopt more than one class as they progress.

The CODA System terms character leveling advancing and refers to characters as having N advancements rather than being of a particular level. Advancing gives the player a number of picks with which to buy upgrades to their character's statistics and abilities.

Characters have a total hit point pool segmented into health levels; each health level of damage incurred imposes a wound penalty to certain actions. Characters also have a number of 'weariness' levels; extended or intense activity can result in penalties to certain actions based on the number of weariness levels lost.
