Confirmed town is, in fact, pretty powerful. Your passive ability is at least as powerful, especially if it comes with a vote, because you become a confirmed townie who CAN'T BE KILLED. Your logic on trying to save it until endgame seems very intelligent and pro-town. However, I disagree with point 2 of this statement in ISO 31:
At that point, I was pretty much the choice for getting the Ring tonight. Nonetheless, claiming before imminent death (which, ironically, was L-1. Remember when that wasn't a big deal? Oh yeah, that was when someone ELSE was at L-1.) However, I see no scum-benefit worth making this claim. If he's lying, we'll find out quickly tomorrow, and he'll be the lynch. Additionally, there's no way for him to fake it unless this game is super-bastardly (i.e., the mod lies). And if we DO imbue him, and he becomes confirmed, that makes our statistical chance of lynching scum that much higher.In any case, since the primary function of my ability is to save myself from being mislynched, claiming it at a time when 1) I was facing imminent death and 2) we weren't really sure who to imbue seemed like a decent move.
He's played scummily, and if the two people (which should be chosen by the town, btw) do not receive a PM that says he's confirmed, then he gets rope tomorrow. However, having a confirmed townie is a very powerful asset for the town, so I think it's worth giving him the Ring tonight.
P-EDIT: Anybody else beginning to think Gandalf is a jester?
