Honor: Honor is a new score,
http://www.d20srd.org/srd/variant/campaigns/honor.htm for more info). A player’s Honor score represents how well an Immortal can follow the rules of the “Game”. You apply an Immortal’s Honor modifier to various skills, feats and powers.
Players begins with an Honor Score between 0 – 25 based on his alignment.
The Immortal's Honor score is only adjusted on how he acts by the rules of “The Game”. The Immortal is free to act anyway he wishes outside of the game without an effect on his Honor score. A DM’s review of the Immortal’s Honor score can be at anytime it seems necessary; but a good rule of thumb is to check it after the end of an adventure or story line.
Remember that is harder to gain honor than too loss honor. Honor is a set of rules that an Immortal plays and/or dies by.
A player’s Honor score can be increased or decreased based on the DM’s judgment on how well the Immortal abides the rules of the Game. This based on the DM judgment, but some violations of the “Game” have some set loses.
Some examples are as follows:
Exposing the Game to mortals, is a lose of 1 point of Honor.
Teaming up against another Immortal (i.e. two on one) is a lose of ¼ of the Honor score.
Attacking on Holy Ground is a lose of ¾ of the Honor score by the attacking Immortal, and ½ of the Honor score of the defending Immortal.
These are but a few examples to be used as guide lines, the final judgment is up to the DM.
