When creating the role list for this game, roll one die for the alignment, another for the role, and another for the modifier. Incompatible or redundant or complementary abilities are simplified (2-Shot Vanilla Townie becomes Vanilla Townie, or if you somehow pick two modifiers and get Even-Night Odd-Night Werewolf Vig, it becomes Werewolf Vig.)
Example post:
Mafia
Fruit Vendor
Odd-Night
