Larian Studiosโ Baldurโs Gate 3 may not be as moddable as Bethesdaโs Skyrim, but the beautiful and brilliant D&D adventure is home to some absolutely cracking mods. Alongside smaller mods to add features like player housing, some fans are working on absolutely massive custom campaigns that add entirely new games to Larianโs game.
One such mod is the in-development Mad Mageโs Domain, a massive adaptation of the Dungeon of the Mad Mage adventure that is being built within Baldurโs Gate 3. One of the first ever adventures designed for 5eโs level 17-20 characters, the ambitious mod is being worked on by a team of 400 volunteer fans, and itโs already shaping up well.
Speaking to FRVR, Andromeda, the Executive Director on the project, explained that the upcoming custom campaign aims to replicate the โchoice, consequence, and reactivityโ of Baldurโs Gate 3 with a whole host of new content that adapts the tabletop adventure with brilliant D&D mechanics of Larianโs game. After all, as Skyrim designer Bruce Nesmith previously told us, one of BG3โs biggest wins is how it makes the tabletop game far more accessible.
Prior to forming the mod team, Andromeda explains that she spent months familiarising herself with the Baldurโs Gate 3 Toolkit and its extended Moonglasses editor. Over the past three months, work on the project has ramped up with the modโs full scope properly outlined by its leads.
โWe plan to adapt the entirety of the DotMM campaign to Baldurโs Gate 3, including all twenty-three dungeon levels and Skullport,โ Andromeda told us. โWith a total of 10 companion characters, 500+ named characters, and an expanded level range of levels 1-20, weโve got a lot of work ahead of us, but with an expanding team of over 400 passionate and dedicated volunteers, weโre ready to face that challenge.โ

Andromeda explained that the goal of Mad Kingโs Domain is to take everything great about Baldurโs Gate 3 and inspire a new version of the Dungeon of the Mad Mage tabletop game, including adding a full story that turns the fantastic gameplay of the original into something that more players will want to play through.
โHaving a module with high mechanical depth but little development to the story and plot allows us to create something truly unique and this is the reason we chose to adapt the Dungeon of the Mad Mage to Baldurโs Gate 3,โ she explained.
With this in mind, the custom campaign aims to add 10 custom companion characters, โnot including the possibility for further temporary or camp companion charactersโ, to support the new story with an emotional core. After all, for a CRPG like Baldurโs Gate 3, strong companions are really the draw.
โOne of the struggles many players and DMs have with the DotMM campaign is that itโs so expansive with little overarching plot structure or story to carry it along,โ Andromeda said. โOne of the benefits of developing a mod adaptation of this campaign is that we get to take the time to fully develop the story, flesh out companion characters, and allow players to experience the campaign in a new way. Baldurโs Gate 3โs dialogue system in particular and structuring of the plot through acts allow us to develop a rich and expansive story that we believe will greatly enhance this infamously large campaign.โ
As with any mod of this scale, they explain that there have been a few issues getting the project running. While there are a lot of volunteers willing to help, the modโs leads have had to find ways to manage everything, and thatโs one hell of a learning experience.
โThe main challenge weโve faced is that due to this being a free, volunteer-based project, we havenโt been able to find a high-quality, free project management software to manage such a large team, so weโre having to establish workarounds and custom systems for the project, but the passion and dedication of our team has kept challenges like these from being a major roadblock,โ they told us.
At the time of writing, Andromeda explains that the Mad Mageโs Domain custom campaign is a โmulti-year projectโ and the team is โnot announcing a release window for the project or even the demo yetโ as the team wishes to hunker down and simply work on what they want to create, similar to other huge mods like Skyblivion and Fallout London.
All in all, itโs a very ambitious project, and one that shows just how dedicated the BG3 community still is as Larian moves onto pastures new. (Well, unless that Nintendo Switch 2 port ends up being real, which we hope it is!)
Additionally, if youโre an ambitious fan of Baldurโs Gate 3 and you want to help bring the Mad Mageโs Domain to help, the team is still looking for โlevel designers, visual designers, sound designers, composers, modelers, animators, and codersโ interested in volunteering.
