When I say role, I mean name. Now that I look back at the OP, I guess it really doesn't necessarily have to be true.
Nonetheless, Roleclaim=Nameclaim here.
If someone nameclaims, they only forfeit their next chance to use the ability (if any). Not throughout the whole game.
Here's two case scenarios:
Evil hatmoza: I like to lie ... a lot in mafia. So I would definitely lie about my role since I learned how to exploit people's gullibility. I will then use my super annihilation attack that same day/night with people thinking I forfeited my attack :3
Saint hatmoza: I would genuinely roleclaim, clear myself -knowing that I can't use my super anihlation attack until the day after tomorrow :3
