Characters in D&D are the pinnacle of power. They are stronger, faster, and wiser than almost any other individual within a D&D world, but absolute power corrupts. Corruption points represent the fundamental idea that those who use power will be corrupted by it.
Corruption takes on many forms, from avarice to sloth to pride to greed, but its primary goal is to destroy those who try to wield it for their own purposes. Those who tap into the power of corruption often bring pain and suffering on to those who surround him, because that in turn destroys the user and causes even greater harm.
Players Tapping into Corruption
Any time a player needs a little extra help, a player may elect to take a point of corruption. The player may immediately spend the Corruption Point on the action they are attempting. Once the action is resolved, the player gives the corruption point to the Dungeon Master. A player may take as many corruption points on a single action as they see fit, there is no limit per encounter, but the limit on action points still applies.
Lisa has spent an action point on a skill check in order to avoid the final failure on a Skill Challenge. Unfortunately, after re-rolling, she still has not exceeded the Difficulty Number. She elects to take a Corruption Point re-roll her current roll and succeeds on the roll. Once the check is resolved, she hands a token to the DM, who now has a corruption point to spend against the players.
Dungeon Masters Tapping into Corruption
Once a player has completed their action using a Corruption Point, they hand the point to the DM. Corruption Points act as Action Points for the DM and his monsters. Any time the DM wishes, they may spend a point to gain the benefits of an action point for the monsters opposing the players.
The other option for the DM is to compel the player to perform a specific action. This cannot be something that will harm the player directly. It can be used to encourage the player to do something that indirectly harms himself or another character, or benefits the monsters (i.e. fall asleep on watch, forget to check the locks on the doors, etc.). This is the nature of corruption. A compelled action does not always have to be harmful in some way. It is also a tool for the DM to push players in a specific direction. The GM may want to the players to take a specific path, and this can be accomplished with a corruption point.
If the DM elects to compel a player, the character must take the action the DM compels. A player may resist the urge of corruption nagging at his mind and soul if they spend an action point to resist it. When the player does this, the action point is spent, as is the corruption point. The DM may choose to up the ante and spend a second corruption point to compel the player. The player may then elect to counter with a second action point. If the player does so, then corruption has been resisted, and the action and corruption points are spent. If the player is unable to resist the influences of corruption, because of a lack of action points or accepting the DM’s compel, then the character must take the action the DM described.
The DM does not have to spend the corruption point against the player who used corruption. In fact, it is more dramatic and thematically accurate if the corruption point is used against another player. Corruption’s influence often effects those who surround themselves with corrupted individuals, and there is only so long that a character can resist its siren call.
When a DM compels a player towards a specific action, players may vehemently disagree. Some discussion is appropriate, and the action must fit with the personality of the character. Actions decidedly out of character can be argued against. If the DM insists, then every player at the table, including the DM, may vote. If the majority say it is an unacceptable compel, the DM must change the nature of the compel until the majority rules with the DM.
DM’s must be careful with the use of corruption points. It is easy to abuse the power granted by compel. They should be careful to use them in ways which enhance the story and create better drama. The corruption points should never be used vindictively or simply to abuse the players. Corruption points are powerful tools, and while players know the risk of taking on corruption, they also expect the DM to be fair.
