из Вики: - Make the Amnesiac’s ability guessable, so that the Amnesiac can figure out what their ability is over time. Learning a piece of information each night, or a power that affects the game in a way that the Amnesiac notices, are both good ideas. - You can make the Amnesiac’s ability slightly better than a normal Townsfolk’s ability. Not knowing what it is, the player will need to work harder to receive its full benefit.

вот еще официальные пояснения. Подчеркнул ключевые тезисы.

The Amnesiac’s ability should always be beneficial to their team – it’s important to remember the Amnesiac ability is not there to allow you to balance the game or help Evil, it’s a Townsfolk character and therefore should be overall beneficial to good (Bounty Hunter and other evil Townsfolk scenarios left aside). Even more so because the player is going to be unsure of how to use their ability for several days, so will almost certainly not be using it optimally, so it’s generally recommended to make it slightly stronger than the average Townsfolk to counteract the fact they are going to have to spend some time guessing what it is.

Their ability can be anything, from just copying another character ability in BOTC to something you’ve completely made up. They can wake every night, each night but not the first, not wake at all and instead have a fully passive effect, wake under certain conditions etc, affect setup, any of the templates for types of characters that already exist in BOTC are fair game.

In general you should bear in mind that an Amnesiac ability isn’t fun for anyone if they don’t at least work out a vague idea of what their ability was. As is demonstrated with other rule-guessing games, you’d be surprised at how hard it is to guess even a very simple ability, so if in doubt, go for an ability that you think is a little too easy to guess and then tailor your ability difficulty over time as you see how players deal with Amnesiac abilities.

It’s generally recommended to start off with each night or each night* abilities, to at least give the Amnesiac some data to work from to find out whether they get info or select players or something else – a fully passive ability, a setup affecting ability or something that has to be triggered specifically by the Amnesiac are all both very hard to guess and very boring for everyone if it never happens.

The Amnesiac’s guesses can be phrased however they like, they don’t have to guess a fully worded ability in order to get a response (though they obviously cannot get a Bingo without doing so). So, for example, asking “Does my ability relate to whether players are evil?” is perfectly legitimate, but even if the ability is the very similar “Each night, choose a player, learn if they are evil” they would need to phrase their question more specifically in order to get a Bingo or, usually, even a Hot. Please work with your Amnesiac, however, to try to make sure you’re clearly understanding the questions they’re asking! Also, no-one enjoys pickiness in this scenario, if their guess is a few words different but functionally the same as the ability, please just give them the Bingo.

You should always answer with the specified answers given above unless you have announced before the game starts to all players that you answer differently. If you use different answers to the standard and your players don’t know, it becomes impossible for someone to bluff being the Amnesiac.

последний абзац как раз про стандартность ответов СТ. Нужно говорить строго: - холодно - тепло - горячо - Бинго И только так. Чтобы за Амнезиака можно было нормально блефовать. Если говорить иначе, типа "ДА"/"НЕТ" - то нужно об этом объявить городу.

"Бинго" = "Да" при 100% угадывании?
