Kennigit:
Token non-demon.
Sprig:
Did not protect against injuries or strength reductions, only death.
bladescape:
Winston got all of his strength from bladescape.
KingMorgan:
Not a tracker as people seemed to think. Did not see where target went, and it only registered whether or not they physically left their room (which many abilities didn't). The following people physically left their rooms:
Lord Medical (healing, though this was a day ability)
Lord Scribe (sending messages)
Lord of District 3 (protecting)
Lord Protector (blocking)
Lord of District 1 (stealing)
Lord Chef (increasing strength)
Lord Financial (bribing)
Inspired by a similar role in Border of Life, and by getting tracked N1 in two simultaneous games (Takhisis' game on the org and High Society) and N2 in another around the same time (Red Dwarf). Kennigit's ability had the same "physically visit your room" qualifier.
landlubber:
Got a brief description of the target's ability without too many details (e.g. he discovered Visor was a mason, but not the specifics). Scum abilities were designed to not be incriminating, with the possible exception of spaceman' ability.
robbiecon:
Designed to be used as an item scan of sorts, though apparently robbiecon was under the (mistaken) impression that he could not return the items.
Jarrema:
Winston probably would have been lynched if Jarrema scanned him when his strength got really high.
Takhisis:
As with abilities, scum did not have incriminating personal goals, again with the possible exception of spaceman. However, a perceptive player might recognize that while town PGs only mention "town enemies," both of the Demon Coup PGs specified "Blood Mage".
Legato Endless:
Counter to the scum's strength reductions.
choxorn and Visorslash:
I still don't understand why Visor claimed vanilla and so stubbornly insisted he had no ability. This role was inspired by a very similar role in Border of Life.
Double A / Internet Flea:
I think I got the idea for this ability from somewhere, but I can't remember where. Maybe Chronomancy?
Snerk:
The only item in the game that could be used by someone else (and thus the only one that would go up for vote). This was the game's tie-breaking method.
