D&D 5E Charisma 1 ...

[Lidgar]

I definitely recommend making the character completely forgettable, unable to get across his messages or intent, coming off as a total wallflower. I wouldn't go so far as to make the character stand around doing nothing (that wouldn't be fun for the player), but his every attempt at social interaction is ignored or dismissed.

Agreed. The character has zero personality, and is unable to interact socially even at the most basic levels. Basically a robot that can think and act for itself but is totally unable to relate to others and others are unable to relate to it. Almost alien in nature, but certainly evokes little reaction from others other than perhaps mild disgust/distaste or curiosity.

I wouldn't bother comparing with monster stats, because monster stats are dumb. Things like saying "he's got no personality at all" is kinda silly too. Someone who's bland is just bland. This guy is offensive. He is literally the most annoying person you have ever met or seen on tv.

He is...
jar jar binks.

Due to a Curse, character has a "1" in Charisma, until a Remove Curse can be obtained. What effects does this have in the game world, other than the obvious negative modifier to Skills, Ability Checks and CHA Saves?

Charisma is influence and likability. You can play it a myriad of ways that represent being someone uninfluential and unlikeable.

Everyone behaves as the character is an object.

A character despised every time he spoke, might turn to despicable actions such as becoming an assassin.

I'd play it as the character losing their sense of identity. You're just so bland, you get pulled along with others. You don't voice your own ideas, you don't really argue, you're a total pushover. And everyone notices this, in the way that you notice-but-don't-notice people who have no presence at all in a social situation.

you are bland. So bland your mother forgets your birthday. And you are an only child
Or if the pc comes up with an idea, the whole table thinks another pc came up with it.
The group's reward is always reduce because the npc forgets to count you.
The waitress gets your order wrong in all the taverns. And the inn keeper double books your single room.
Dogs sniff your leg and go do their business elsewhere.

I use the Loyalty option for NPCs, so if the character's former Charisma score was the highest in the party then the Loyalty scores of any NPCs with the party would drop by half the difference between the cursed character's original CHA and the next highest CHA in the party, potentially leading to the NPC failing any (houseruled) Loyalty check I may call for as DM.

While I like the idea of 1 charisma meaning that you are the ultimate wall flower (you make so little impact, negative or positive, that you might as well be invisible), I think that would be boring to play. I think he reason I would go with physically repulsive, even if that isn't based on the full meaning and utility of charisma, it at least has the potential for being interesting, for having plot impact. If the player is just a robot, totally flat effect, incapable of expressing emotion...that could be boring for everyone.

One way I could see it working is that the player is instructed to play as he normally does. He still has his INT and WIS. INSIDE he is the same, CHA is how you impact other sentient beings. But no matter how he interacts, it just has no impact. Maybe the curse is that he is "locked inside his own head" like a daytime drama representation of someone with extreme autism. The party, who know him before and would go to great lengths to draw him out and interact with him will at least be able to communicate and work enough to get basic concepts accross, but to every NPC, there is nothing there to them.

What I like about this is that the play need not role play the rain main or a try to role play a brain-dead automaton, which can be boring, awkward, or even offensive. Instead, he can play as normal, but the results of any social interactions just are not what he intends. He is ignored. He is picked on. People get offended for seemingly no reason. People feel threatened by this mentally defective but physically (or magically) powerful adventurer and believe he should not be allowed to roam free. People accuse the party of taking advantage of him.

This would be FRUSTERATING for the player, but in a way that remains interesting and impactful. It would not be boring (if the DM does his or her job well) and it would not devolve into silly "me so ugly" antics. The player--and so the character--would have a strong incentive to find a way to lift the curse but not feel like he or she has no agency in the meantime.

Depends on your take on charisma. Maybe now you're just horribly inept at speaking in a manner that garners people's attention. Maybe you're ugly as a butt. Maybe a little bit of both. From a mechanical standpoint, it means your charm-related saves suck and you should probably avoid making checks that involve talking to people.

I'd talk to your DM to see what his intentions are, maybe you're ugly and uncharismatic.

Personally, since I don't like to step on the toes of people's character's appearances without very strong reason to do so, I'd say you're like one of those pretty girls at the bar, great hair, drinking the good drinks, nice boobs then suddenly she opens her mouth and you have the strangest urge to stop drinking, get a nice job and go thank your mother for raising you right.
