AITA?
Context, this just happened a couple hours ago, I write this as fresh as posible, so let me get you all in context:
We have a little dnd group, me (artificer), wizard, artificer 2 and DM, in our group I've always been the DM, we just finished a campaign in the fallout universe, we aprticipated with a couple more player, in that campaign I did the usual DM stuff, trigger alert, talk to player, be understanding and you know, understand that DnD is a teamwork so we all can have fun, DM in that campaign was a doctor, so i created them a special system of medical actions so he could play without killing anyone, and when he wanted to engage in combat I created a special tazer for him, I'm telling this so is in context that I actually cherish my players and "friends", the few times I say no I explain myself, stablish boundaries and make agreements, so DM decides that now he wants to try being a DM, me and wizard are specially excited because she is my partner, so be able to finally play together was awesome, he prepared a oneshot, a classic medieval setting with a couple steampunk elements, the plot... was something weird, so, let's go to session 0
We get the setting... and that's it, no plot, no context, we just need to create characters, wich we all found very weird, because we could end making characters with no good reason to engage in the plot, and that same thing has happened already, so we push a little so we could have some more context, the most we could get is that an inventor lost his blueprints and we needed to found them, ok, we can work with that, we also got more info about the town, apparently was some kind of technocracy where knowledge is highly regarded, so wizard makes.... a wizard, I decide to make an artificer, artificer 2 obviously do that too, I decide to make a battle smith and they made an alchemist, now, I need to get into techincal details here
I made an Aarakocra who is a smug and lame know-it all, kinda like berdley from Deltarune, with an obvious character development, now to the tecnical details:
s: 12, d: 16, c: 14, i: 16, w: 8, c: 8
You can see that we used the point buy system, I actually was the one who suggested it, because rolling dice we have had some characters start with 20 in some stats, and I wanted him to not have issues in his campaign
As magical items I decide to create a shield+1 and a heavycrossbow +1
I grab a leather armor with 13 ac with the starting gold, so 13 plus 3 from dex and plus 3 from the shield was 19
My spells were: cantrips: guidance, mending and mage hand, level 1 spells: heal wounds, feeric fire, grease and identify magic object, from my subclass I got shield and heroism, I got gust of wind from my race and from my starting feat (rune carver) I got Comprehend Languages
As you can see all of them are basic spells from the corebook
Whye do I got so technical, well, after I showed him my character everything seemed allright, then he told me i couldn't have the robo-companion because fo lore reasons, I said okay, then the tolde me again that it was fine, but at moste he could only work with steam, ok, cool
ff a couple days DM says the session will be moved to next weekend, bum, but whatever, is fine, I get it, wizard decides to ask him directly, and apparently mi character was too OP?
He said that I was using a bunch of homebrew stuff, an unffair made up race, and, for some wild reasin he said that Aarakocras should not be artificers...... HUH?
Anyway, I know that the DM has the last word, so I'm patiently waiting for the DM to talk to me and tell me what's wrong, ff from monday to saturday, today, he told everyone but me that he was cancelling the session, again, he hasn't talked to me since I presented him my character and he said it was ok, remember that, and he told wizard that IT WAS MY FAULT?, that I made a character so I could screw him over in his first campaign, and that he showed the character to other people and he said I was an OP min-maxer who used unffair technices?
I'm not stubborn, I he would have just talked to me we could have worked something out, instead he went behind everyones backs to spil them the story, and that the one-shot wasn't happening, everyone but me, I tell wizard to please tell DM to talk to me, I¿ve been trying to talk to me, and when that finally happens he says that he is only doing that as a courtesy to wizard... HUH????
He then procced to tell me that the main reason he was backing off was my character's fault, that I "should have know better", "I showed other people you character and told me something was fishy"...... THEN WHY YOU DID NOT TALKED TO ME?, I obviously didnt yelled at him, but I was pretty pissed, he offers me no explanation and he says "you are taking this too seriously"
Bro.... like you come to my chat literally to tell me that my character is your campaigns 13 reason why, refuse to talk to me for a week and then you only come as a "courtesy fo wizards' petition" but I'm taking it too seriously?..... "Yes" he said
I'm honestly shocked, I don't know what could I have done to deserve this, like, I'm always helping, making sure everyone is having a good time "oh yeah, I know, love what you did for me", THE AUDACITY OH MY GOD
Then he said "but I'm chill, I don't want to expose you as a campaign ender", honestly that pisssed me of so much that I told him "You know, you should do it, tell everyone that the reason you are cancelling this is that you send a character sheet to some dudes, they felt that the sheet was shady and without telling anything to the characters author I cancelled everything", he said okay and send the exact thing I told him, like literally, I said my goodbyes and left the group.... AM I THE A**HOLE?
TL;DR DM decide my character is too OP, tells me nothing about it, ignores me for a week and cancel everything
