Let's say I made an app or even a game based on dungeons and dragons that help players of the game get through their adventures. But I called it a dungeons and dragons game and used their rules and everything. And credited them on the logic and rules and originating from them. Would I get in trouble. Or how would I go about releasing it and stuff

Its a risky domain. As long as you are not using the words " dungeons and dragons " or the original game characters or graphics or anything related to game except the logic ,then you are good to go. Case in point a millions of pubg like battle royale games which does not get banned.

@curioustools but I was gonna base the rules the characters and all that type stuff. So I can use the spells and moves and logic and rules but put a different twist and and name to them

If you ask for money, or distribute any copyrighted or trademarked materials, you will be sued for copyright infringement at the very least, and potentially also charged with digital piracy, dependent on your jurisdiction.

You're better off making something logically derivative that is your work.

Use the SRD (the free as in speech version of the DnD rules). Some content is not available in the SRD, but the mechanics, most races, spells and items are the same, and you will not be sued. Then add the possibility for players to add their own items, spells etc. so they can add DnD content themselves without you risking to be sued. Just like Roll20 does.

@pipe that's the thing. I don't wanna make it seem like I'm deriving from them. It was a app/game that helped with the overall sessions of DandD

„Dungeons and Drags“

@M1sf3t who copycatting anything. If you read correctly and stop being so hype. I just want an application that'll make my d and d sessions go smoother and quicker. Not making my own game and basing it off anything. The app is a a direct application to play the game

@SonKykun Sorry bud, but this idea has been pitched like at least three times just in my circle of friendship.

Do you wanna know how many tried to make this app already? Too many!

@M1sf3t I fall under a copycat category because I wanna make an application to make d and d experiences easier? And yea. Being hype. As in thinking you know what you or I was talking about. Like I said. Ain't no one trying to make a game, base it off d and d and sell it as my own. I'm simply trying to make an application that will make playing d and d easier

@SonKykun That’s an supportive application then, but you’re talking about „basing“ right off the bat.

I’d be quiet if I was you, especially with -1 already, oof

And leave this cute dreadlock bob Marley alone @M1sf3t

@010001111 by basing I mean the application would be based off d and d period. Not based off d and d and tweeked a bit. But point blank period the application will be an application that's uses d and d to get people though their sessions. But rd. I get it. I found out about licensing products and such. Which was what I was looking for from the rip. Y'all start saying anything

@M1sf3t the first people to tell me something was saying I could do it if I changed some things a bit like names and such. So I was trying to further explain that I wasnt trying to make something and call it my own. Just wanted to make an app that would make d and d-ing more efficient. But you a programmer?

@M1sf3t oh OK. True. So at the end of the day I have to get the owners permission to drop an app that makes there product more easier and efficient. Even if I'm acknowledging and basing everything on their product. Because at the end of the day I'm using their product to make my product

@SonKykun You ask if you're risking anything by using copyrighted material in your app. The answer is yes, bluntly and simply. Yet you keep justifying your actions to people as we were the lawyers that were going to sue you.

Anyway, if you keep that app to you and your friends, you don't risk anything.

If you want a more nuanced answer, tailored to your specific situation, country ans intentions, contact your lawyer and ask him. It may be that by writing "DnD® all rights reserved" somewhere you could be left alone, but we're not the experts you're looking for to answer that.

(Edit: I've not read your last answers before writing this, don't pick on me if this comment seems contradictory with what you last said. Still, the advice given in the last paragraph still holds up if you want a real and trusted answer)
