Mafia 74. Dance of Life and Death

what are notes? I've never played with them before.

The player sends a message to the GM, similar to a forum post, with a note like "this is my note," and the GM inserts it after the newspaper. Notes are anonymous; they can be used to reveal a role and any information obtained about it, but they cannot reveal the author's identity. In some cases, the author can directly state or subtly hint at who they are targeting with their night action on the night the note is sent (depending on the rules set by the GM). However, in this game, only one role can write notes, and only after their death, and I make fairly obvious hints about the roles of the killed players, so the anonymity will be purely formal.

is this done during the day?

Yep.

will the nickname of the person whose voice was stolen be displayed?

Nope. Only the fact that the voice was stolen. "Tonight, there was a particularly strong smell of roses" or something like that.

will the person whose voice was stolen know about it?

I won't tell them, but the player will probably be able to figure it out under certain circumstances.

what is this, and how is it different from freezing?

Isolation applies for one turn; freezing lasts until the end of the game (or, of course, the death of the freezing player or their voluntary release of their victims). An isolated player cannot use their night action, but no one can use a night action on them either. It is considered protection (i.e., it can be bypassed by some killers).

to be more precise: it redirects the night action of the selected player to the selected target, right?

Yep.

in this case, should the phrase "the fact is displayed" be understood as meaning that the nicknames of both targets are not displayed?

Yep. "Today, a bunch of spiders were crawling on the ground" or something like that.

is it displayed in any case, even if healing was not needed?

Yep.
