Sins of the Unforgotten

The Sins of the Unforgotten are a set of irreversible slits on the wrist that signify that the corresponding character has cheated in-game, or, for NPCs, has committed an act that is outside of normal parameters.The sins first appeared in Episode 6, the first, of course, being committed by Rob.

About the Sins
The Sins are signs of powerful "guardians of the realms" trying to break into the body. Each character has a limit of 5 sins, after which the guardian will take possession over the body. Each member of the Order of Chaos has committed all 5 of their sins and has been taken over by a demon themselves.

Sins in Action
The Sins can supposedly only be performed by certain people in the Unforgotten Realms, notably Schmoopy, Eluamous, and Nador. When one gains a new sin, the person gains a slit on their wrist and feels a pain in their chest reminiscent of a heart attack.

Rob

 * Blew on his dice to land a critical hit
 * Moving Roamin's piece to the party's location
 * Carelessly reading through Mike's plan book
 * Tearing up one of Timmy's character sheets, to which Timmy responded that he made photocopies, making the action useless.

Mike

 * Switched his dice with the dice being used to roll for Elizabeth Cacklebird's attacks and reflex saves, but it is considered that his sin is in using a spell that is virtually forbidden.
