如果变种人对”我是外来者“疯狂（表现得像个外来者或让别人认为你是），变种人可能会被立刻处决。
在进入第一个白天前几秒钟，变种人向其他玩家说他是变种人。说书人声明变种人被立即处决行。由于每天最多一次执行，今天无法再提名处决。
女巫私下与说书人谈话，A是一名变种人，女巫告诉说书人：A说他自己是笨蛋。说书人选择立即处决变种人。
变种人告诉其他玩家他是一个村民，但是不说是哪一个。其他玩家怀疑他是变种人，他没有反驳。经过一分钟左右的沉默，说书人处决变种人。
变种人说他是祭司，给了一些虚假的祭司信息，然后说“顺便说一下，我绝对不是变种人”附带上了几个微妙的眨眼，说书人选择立即处决变种人。
Never admit to being the Mutant. Never even admit to being an Outsider. "Admitting", of course, is a tricky thing to define. In Blood On The Clocktower, the term "mad" is used instead. What this means, is that if you try to convince anybody that you are the Mutant, the Storyteller can (and should) execute you immediately. Or, if you try to convince the group that you are an Outsider, the Storyteller can (and should) execute you immediately. This is the judgement call of the Storyteller, and the Storyteller will make their decision based on what they think you are trying to do, not just the words you use. For example, if you tell the group that "you might be the Mutant, but might not be", then the Storyteller may judge that you are trying to convince the group that you are the Mutant, and execute you. Or, if the whole group is asking what your character is, and you stay silent, refusing to say who you are, then the Storyteller may judge that your silence is a way that you are trying to convince the group that you are the Mutant, and execute you.
Be proactive. Don't stay silent. As discussed above, Mutant players that stay silent the whole game tend to get executed by the Storyteller. If you talk, pick a Townsfolk to claim to be, and do your best to convince the group that you are a character other than the Mutant, then you almost certainly won't get executed. For example, if you spend the game convincing people that you are the Oracle, and give the best, most sensible sounding information that you can, you won't be executed. And, if the Demon kills you because they think you are a threat, then that's fine too! After all, if you die at night, it means that another good player (which, statistically speaking, would have been a Townsfolk character) doesn't die instead.
Deliberately coming out as the Mutant has some benefits and some drawbacks. On the one hand, if your execution goes off, you will be confirmed as a good player, and everyone will believe you. On the other hand, that's an execution that the good team don't get to dictate themselves, and if you go off too early in the day, you can block characters like the Savant. Artist and Juggler from using their abilities. Finally, the storyteller may simply choose not to execute you, which will leave you in an ambiguous state of unconfirmed despite not satisfying the madness of your ability... which will make you look especially evil.
Come out secretly to one or two players you trust. You're going to be bluffing as a townsfolk, which can look suspicious and cause problems for you down the line (especially if your information isn't adding up with what the other players are getting). Admitting the truth early on means that the people you trust will know to discount your information and protect you from accusations. (Additionally, knowing about your presence can be particularly important for determining if there is a Fang Gu around!)
Beware the Storyteller! They will be on the watch for you fulfilling your madness, and it won't take too much for them to execute you, thus denying the good team a chance at killing the Demon! Avoid mentioning your true identity within earshot of the Storyteller, but also be wary about revealing to suspected evil players - they can tell the Storyteller what you've said, and get you killed that way!
The Mutant is an excellent fallback bluff if your more difficult/risky claim is falling apart under you. As a Mutant, it would make sense that your Oracle information doesn't add up, since you're lying to cover for yourself!
If you reveal your "identity", the Storyteller can't execute you, since you aren't actually the Mutant. Blame this on the Mutant's "might" condition - the storyteller only executes you at their discretion, and might spare a Mutant to make them look more suspicious/avoid confirming information for the town. Claim this is what is happening when you are not executed.
"Reveal" secretly to a couple of players to gain their trust. This is a good move as a regular Mutant, and if they believe you, they'll cover for you when other players become suspicious of your haphazard or confusing information claims. Because your death is an execution that takes control away from the good team, players will be compelled to protect you and your identity. This will also serve to keep them preoccupied in the meantime, which is a nice bonus for you!
The Mutant doesn't have a lot of information, and is a hard bluff to pull off logically. Try to play the 'emotional' side of the character instead. Appealing to people to help safeguard your true identity, acting nervous around the Storyteller and players suspected of evil, and trying your best to be helpful are all hallmarks of a real Mutant player!
One huge advantage of bluffing Mutant is the ability to confuse the Outsider count. Urgently whispering to good players that "that Sweetheart is lying, because I'm the real Outsider!" introduces the danger of a Fang Gu being the demon in play. At the very least, it casts doubt on existing Outsiders when they come out, since you've added yourself to their number. The secretive nature of the Mutant makes this an especially potent tactic since you can (and should) convince other players to argue about your existence for you, meaning the poor real Outsiders will have a harder time confronting you directly and tracing your terrible lies back to your evil team!
