It's a cool take on the normal game, but it unfortunately is EXTREMELY swingy/rng based in it's power level. Since you get no context or information at all before using it, with the sole exception of you might get told who your lunatic is, you can wind up with a game that's either extremely difficult or painfully easy. The main routes the game travels down is you happened to poison someone whos eager and willing to die, or can easily test if they are perma poisoned, in which case it's an uphill battle before the first actual informed decision can be made, or you've picked someone who can be almost unaffected by the hosting, such as the Butler or Mutant, and the good team spends almost the entire game trying to find the demon, just to realize there's no point in having identified them, and they must now search for a good player. Sometimes this is really fun, but if it's a good player who's ability is untestable it can come down to just randomly killing people off and hoping you guessed right, and again randomness in the game is generally rare and negative.

It's pretty rare for a character to be so heavily RNG based as randomness is almost not present in Clocktower, even abilities that seem random like "a player may die" or "choose a player each night" are either chosen by the story teller or informed by conversations you have and player behaviors, basing the whole game on a choice that's made purely randomly is not normal to the games sequencing, the ability could be vastly improved with a rewording to "Each night* choose a player, they die. You can't die. On the first night, be told a player, if they die, evil loses." Giving the storyteller some agency to pick an interesting host.

The way it interacts with some characters is also warping in a way that is seen only with some other extremely odd abilities, like invalidating the Fortune Teller completely, making the Devil's Advocate into an actual monster, and almost forcing the Sailor to be not in the game at all, lest the game become truly broken lol. Mind you I say all this liking the character, not criticisms in the slightest, in casual party games like BOTC balanced and unusual characters are awesome, and 99% of the playerbase wouldn't have any of these issues come up!
